200V 500A Plasma Plating Rectifier Chopper technology rectifier for plasma coating, IGBT chopper output current with high precision and good ripple coefficient, can meets the high requirements of plasma coating.
The AC input voltage is filtered by the transformer and rectifier circuit to get the high voltage DC, and the high voltage DC is chopped by the BUCK chopper circuit to get the required output voltage. The control circuit samples the output voltage and output current, and produces a pulse width modulation (PWM) signal to control the BUCK circuit after closed-loop feedback, so as to keep the output voltage or current stable.
This Plasma Coating Rectifier Project implementation demonstrates China’s advancements in precision power supply technology, particularly for surface engineering applications requiring strict control of coating thickness and quality. The robust design has been successfully applied in domestic PVD coating production lines, showing 97% operational reliability in continuous industrial environments.
