The power chopper is designed and made, based on the ultrasonic vibration parameters detected by the high-speed micro-displacement laser sensor, the chopper pulses are given, which may turn on and turn off the micro electrical machining power, so that orderly synchronization can be fulfilled between the micro electrical machining power and the ultrasonic vibration in real-time way, and the electrical machining system is improved. Using high-frequency pulse voltage that amplitude is less than 6 V, t
