Abstract

This paper describes an optimized digital control system of high power intelligent waveform power supply for electroplating. In order to meet the requirement of high dynamic response of each power unit outputting intelligent waveform and improve the stability of paralleled system, the optimization of the digital control system is taken into considered. By reducing the inherent delay of traditional digital control system, the dynamic response is greatly improved, and by introducing the feedforward control strategy, the rapidity and stability of the device is increased, especially in paralleled system. Based on it, an 8000A/24V intelligent waveform power supply was built by 16 power units in parallel.
