The working principle of high-frequency DC adjustable electroplating power supply mainly involves the combination of high-frequency switching technology and electroplating process. Here's a quick rundown of how it works:
High-frequency switching technology: The high-frequency DC adjustable electroplating power supply adopts high-frequency switching technology to convert the input AC power supply into DC power supply through rectifier filtering. Then, the switch is manipulated by a high-frequency PWM (Pulse Width Modulation) signal to convert the DC power supply to a high-frequency AC power supply again. This high-frequency AC power supply is transformed, and then rectified and filtered to obtain the required stable DC output. The high-frequency switching technology significantly improves the power conversion efficiency while reducing the size and weight of the power supply.
Plating process: Electroplating is a process that uses the principle of electrolysis to deposit a layer of metal or alloy on the surface of a metal. The high-frequency DC adjustable plating power supply provides the required DC power supply for the electroplating process, and realizes precise control of the plating quality by adjusting the magnitude and waveform of the output voltage and current. The output of the high-frequency square wave can improve the deposition speed, gloss and hardness of the coating while reducing the loss of raw materials.
To sum up, the working principle of high-frequency DC adjustable electroplating power supply is to use high-frequency switching technology to convert the input AC power supply into a stable DC power supply, and by adjusting the size and waveform of the output voltage and current, to provide the required power supply for the electroplating process to achieve high-quality and high-efficiency plating deposition.
