Features and Advantages of Desktop Power Adapters and PFC Power Adapters
Desktop power adapters are power devices that convert AC power to DC power, usually used to provide stable DC voltage for various electronic devices. Desktop power adapters are characterized by large sizes but high power, which can meet the needs of high-power devices. Desktop power adapters have two series, one is the ordinary model 36W-96W, 12V/3A/4A/5A/6A/7A/8A, and the second series is the high-power PFC power supply 96W-150W. This article will introduce the features and advantages of desktop and PFC power adapters and how to choose the correct desktop power adapter.

Features of Desktop Power Adapters
Desktop power adapters have the following features:

Efficient and stable output: Desktop power adapters use advanced switching power supply technology, which can convert AC power to constant DC voltage and adjust the output voltage and current through built-in control circuits, ensuring the stability and consistency of output power. Desktop power adapters also have protection functions such as over-voltage, over-current, short-circuit, over-temperature, etc., which can prevent damage to the device or the power supply itself.
Wide input range: Desktop power adapters can accept a wide input voltage range from 90VAC to 264VAC, which means they can be used in most countries and regions without worrying about input voltage mismatch.
Diverse output specifications: Desktop power adapters can provide different output voltage and current levels to suit different devices and applications. For example, the first series is 36W-96W, 12V/3A/4A/5A/6A/7A/8A, the second series is 96W-150W PFC power supply, 12V9A/10A/11A/12A. Depending on device specifications, desktop power adapters can also be customized with different DC output connectors and cord lengths.
Comply with safety standards: Desktop power adapters have passed various international and domestic authoritative certifications to ensure their safety and quality.

Features of PFC Power Adapters
PFC (Power Factor Correction) is a technology that improves AC input power utilization efficiency. The power factor is the ratio of input adequate power to input apparent power, reflecting how much AC input power can be converted into DC output power. Ideally, the power factor should be 1, but due to the presence of reactive power and harmonic components in the AC input power, the power factor is lower than 1. Low power factor causes the following problems:

Increase line losses: Low power factor means that apparent input power is higher than adequate power, which causes more invalid power and harmonic components in the line, resulting in increased line losses and heating.
Reduce system capacity: Low power factor means that apparent input power is higher than adequate power, which causes system capacity to be occupied by invalid power, thereby reducing system capacity.
Affect power quality: Low power factor means that apparent input power is higher than adequate power, which causes the supplier to provide more apparent power to meet user demand, thereby increasing supplier cost and burden. At the same time, invalid power and harmonic components also cause interference and pollution to other users.

To solve the problem of low power factor, PFC technology is introduced into desktop power adapters. PFC technology improves the power factor by adding a switching converter at the AC input end to adjust the input current waveform, making it in or close to phase with the input voltage waveform. PFC technology has two types:

Passive PFC: Passive PFC improves PF by filtering out harmonic components with a passive filter at the AC input end and compensating for the invalid inductive or capacitive reactive power required by invalid inductive or capacitive loads. Passive PFC is usually used in low-power applications, but its effect is limited.
Active PFC: Active PFC improves PF by adding a switching converter at the AC input end to adjust the input current waveform, and tracking the input voltage waveform with feedback control, making it in phase or close to phase with it. Active PFC is usually used in high-power applications, and its effect is best.
PFC technology can bring the following benefits:

Save energy: Improve AC input power utilization efficiency, and reduce line losses and heating.
Increase system capacity: Reduce invalid power occupying system capacity.
Improve power quality: Reduce interference and pollution to suppliers and other users.
Comply with environmental requirements: Many countries and regions have strict regulations on the minimum power factor or full harmonic content of products. For example, the EU requires products to comply with the EN61000-3-2 standard, with a minimum practical value of 0.9 or a minimum average of 0.95.
How to Choose Desktop Power Adapters
When choosing desktop power adapters, you need to consider the following factors:

Output specifications: Output specifications include output voltage, output current, output connector, and other parameters. You must choose output specifications that match or are compatible with your device. For example, if your device needs 12V 5A DC power, choose a desktop power adapter that can provide at least 60W (12V x 5A) output power.
Input range refers to the AC input voltage range that desktop power adapters can accept. It would be best to choose a desktop power adapter that can adapt to different regions and countries’ input voltage. For example, if you want to use it in China, you must choose a desktop power adapter that accepts 220VAC input voltage.
PFC function refers to whether desktop power adapters have a power factor correction function. You need to choose whether you need PFC function desktop power adapters according to your device’s power and the environmental requirements of your region. For example, suppose your device’s power is high, or your region has strict regulations on the minimum power factor of products. In that case, you must choose desktop power adapters with the PFC functions.
Safety certification: Safety certification refers to whether desktop power adapters have passed relevant safety standards certification of countries and regions. It would be best if you chose desktop power adapters with corresponding safety certifications according to your device’s use and the legal regulations of your region. For example, you must choose desktop power adapters with CE certification to sell or use in the EU.
Conclusion
Desktop power adapters are helpful to power devices with features such as efficient and stable output, wide input range, diverse output specifications, and compliance with safety standards. PFC technology improves AC input power utilization efficiency by saving energy, increasing system capacity, improving power quality, and complying with environmental requirements. When choosing desktop power adapters, you must consider factors such as output specifications, input range, PFC function, safety certification, etc.

The Production Process of Power Adapter A power adapter is a product of modern power electronics technology, which uses the control of the switch tube to turn on and off the time ratio to maintain a stable output voltage. With the progress of power electronics technology, power adapter technology also advances with the times, with the advantages of high efficiency, low power consumption, small size, lightweight, etc., representing the development direction of regulated power supply. In addition to product design and development, production and manufacturing are important links to ensure the quality of power adapters. The completed power adapters can achieve the expected performance and effects only by adopting rigorous production processes and standards. The production process of the power adapter can be roughly divided into the following steps: pre-production preparation, coil making, component soldering and assembly, cleaning, inspection, potting, casing, Marking, and packaging. Each step has its standards and requirements, which need to be strictly followed by the production staff. The following is a brief introduction to each step and its key points. Pre-production preparation: Preparing in advance according to the relevant technical documents is necessary to ensure smooth and efficient production and manufacturing. This mainly includes the preparation of components, raw materials, and required equipment; the design documents, process documents, test methods, production and manufacturing operation rules, and other materials of the power adapter; some components need to be assembled in advance and their performance tested. Coil making Strictly speaking, coil making is also part of pre-production preparation, but magnetic components are critical for power adapters and directly affect product performance. Therefore, this item is listed separately, and the operators must have a magnetic component qualification certificate. Before winding the coil, determine the winding and performance parameters. According to the standard of magnetic components, determine the material list. According to the performance parameters of magnetic component winding, select enameled wire and skeleton. Cut out the size of each winding wire. Fix the skeleton on the winding machine and do a good job of winding. Special attention should be paid to: the wound coil should be tight and flat; with short inlet wire and long outlet wire; primary first and secondary later; if there are two windings in the secondary when coil turns are the same, wind at the same time; when coil turns are different, wind separately. Finally, twist each winding’s inlet and outlet wires 3-5 turns to prevent loosening. Then take down the skeleton from the winding machine. Arrange enameled wire. Scrape wire and tin. Component soldering and assembly Standard component soldering is a basic guarantee for product quality. It stipulates that there should be no missing soldering for components. Each solder joint should be soldered firmly and in good contact. There should be no wrong soldering components. In the soldering process, it is necessary to: confirm the accuracy of raw materials; preheat the soldering iron sufficiently. Hold the soldering iron in one hand and tweezers or wire in the other; solder in order. Inspect each component after soldering, from large to small or left to right. Check whether it is firm or not. Whether contact is good or not. There should be no offset. Falling off. False welding. Solder joints should be smooth and round. There should be no burrs or other bad phenomena; check for missing welding or short circuit caused by solder flow; or chips. Capacitor. Resistance should be close to the surface of the board. Cleaning refers to cleaning PCB with an ultrasonic cleaning machine to ensure no excess solder paste or impurities are inside the product. Clean twice as appropriate. During operation, ensure that cleaning equipment is installed stably. Pour water and washboard water into the machine according to the standard process. Clean for 1 minute. After cleaning. Dry at room temperature or dry in high temperature drying oven. Check cleaned PCB for false welding. Without welding. Short circuit etc. Inspection is a necessary process in any production process. It is also the last quality assurance before product shipment. Power adapter inspection mainly includes routine appearance inspection. Performance test and high-low temperature test. The routine test is to inspect the packaging and appearance of the power adapter. There should be no damage. Scratches. Dirt. Pin skew etc.; place power adapter under 1.5-10 times microscope. Ensure that the plating has no peeling or blistering. Lead has no fracture or corrosion; use a vernier caliper to measure physical size. According to the customer agreement stipulation. Test input-output parameters. When loading transient or input voltage transient occurs. Check whether output meets requirements. The high-temperature test is to place the power adapter in high temperature drying oven for baking for more than 2H, then quickly take out the product for performance test; the low-temperature test is to place the power adapter in a low-temperature storage box for freezing for more than 2H then quickly take out product for performance test. Potting Potting means slowly injecting refrigerated colloid into body colloid should not exceed components surface should be smooth and flat After potting products are placed parallel on tray at room temperature solidify for more than 48H After colloid solidifies completely can proceed next step operation After product is sealed into one shock resistance performance is improved ensuring product quality Casing Casing uses parallel seam welding machine First place product base on fixture of parallel seam welding machine then take cover plate place on product base confirm cover plate direction According to size of shell to be welded input corresponding shell length width left right electrode height on welding parameter interface after setting all parameters do spot welding work after spot welding work check whether cover plate base are spot welded together then do seam welding work After welding work check welding surface under 20 40 times microscope Welding should meet following requirements: welding surface should be well welded no pores cracks unsealed cover plate deviation other bad phenomena; welding surface should be flat no unevenness wheel marks; welding surface should not be overburned scratched Marking Marking is last step before product shipment mark product make product model pin function easy identify avoid wrong connection misuse Marking uses laser engraving machine input corresponding information on computer control engraving machine engrave information on shell.

As a frequently used electronic device in our daily life, the power adapter is mainly used to adjust the power voltage and current to a suitable range for various electronic devices. As a professional company specializing in power adapters, Oushangmei Technology has always been trusted by consumers for its product quality and performance. Generally speaking, alternating current is a sinusoidal waveform of voltage and current that changes with time. Alternating current has many advantages, such as changing its size through a transformer, transmitting over long distances with low loss through transmission lines, using engines or generators easily generate it, and so on. Therefore, alternating current is the most common form of electric energy daily. However, not all devices can directly use alternating current. Some devices need to use a constant or stable direct current to work. Direct current is a constant or square waveform of voltage and current that does not change with time. Direct current has many advantages, such as it can be stored and released by batteries, switches can control it, and it can change its size by rectifier bridge or switch mode regulator. Therefore, direct current is the most common form of energy used daily. The working principle of a power adapter is to use power electronic technology to convert alternating current to direct current. Power electronic technology is a technology that uses semiconductor devices, such as transistors, diodes, thyristors, and so on, to control and convert electric energy. The main components of the power adapter are as follows: Input filter: used to filter out the noise and interference in the input alternating current and protect the power adapter and the subsequent devices. Rectifier bridge: rectifying the input alternating current into pulsed direct current, providing direct current power for the subsequent devices. Voltage feedback: used to detect the size and stability of the direct output voltage, connected with the control chip, adjust the switching frequency and duty cycle of the switch tube, and achieve the stability and regulation of the direct output voltage. Control chip: used to control the switching state of the switch tube, according to the change of input alternating current and the demand of direct output current, to achieve high efficiency and low loss AC-DC conversion. Switch tube: used to switch the pulsed direct current into high-frequency alternating current, improve the working efficiency and reduce the size and weight of the transformer. Transformer: used to reduce or increase the high frequency alternating current, according to different output voltage requirements, design different turns ratio and the number of turns. Output rectifier filter: used to rectify the transformer output high-frequency alternating current into smooth direct current and remove the high-frequency ripple by filter capacitor, improving the quality of direct output current. Output protection: used to protect the output direct circuit and load device and prevent overload, overvoltage, short circuits, and other faults. The production process of the power adapter can be roughly divided into the following steps: Choose a suitable power adapter scheme according to different output voltage, current, power, efficiency, safety, and other requirements; design a circuit diagram and schematic diagram. Select suitable components and materials. Make the PCB board of the power adapter, convert the circuit diagram into a PCB drawing, then make the PCB board by cutting, drilling, copper plating, etching, and other processes. Assemble the components of the power adapter, solder resistors, capacitors, diodes, transistors, and other components according to the position of the schematic diagram on the PCB board and form the main board of the power adapter. Test the performance of the power adapter, use special test instruments and software, test and debug the output voltage, current, ripple, efficiency, temperature rise, protection function, and so on of the power adapter, and ensure that they meet the design requirements and standard specifications. Encapsulate the shell of the power adapter, put the tested main board into a plastic or metal shell, fix the wiring and plug, then encapsulate and label, and complete the production of the power adapter. High efficiency: Oushangmei Technology uses advanced switch mode regulation technology, which makes its products have an efficiency of more than 90%, much higher than the traditional linear regulation technology. Low loss: Oushangmei Technology uses high-quality components and materials, which makes its products have a loss reduction of more than 50%, saving energy consumption.
