High Frequency Electroplating Rectifier , HF Switching Power Supply 12v 100a

High frequency switching plating rectifier, also called as HF switching power supply:

Which is a new type electro plating machine plating rectifier – high frequency switching power supplies. It combines advantages of silicon rectifier waveform smoothness and silicon controlled rectifiers voltage easy adjustment, while has highest current efficiency (up to 90%), the most smallest volume, and needless to say, it is the most promising plating rectifier. Manufacturing technology has solved the power problem, thousands of amperes power switching plating rectifiers have entered a practical stage of application.

Electroplating high-frequency switching plating rectifier main conversion structure has: forward converter, half bridge, full-bridge, etc., have pulse-width modulation (PWM) “hard switch” circuitry,also have popular phase-shift control “soft switch ” power circuit.Pulse width modulation (PWM) HF switching plating power supply, its operating frequency mostly below 50 KHz, with a voltage or current feedback control.It change the drive voltage pulse width to alter output current by interrupting power flow and adjust the duty cycle method, make the device working in the “hard switching” state, ie forcing conduction (voltage is not zero) or forced shutdown (current is not zero), making the switching power transistor both exist high pressure and large current cross when switch on and off, therefor switching loss less, peak interference strong.
