This paper makes some research on designing and manufacturing a nanosecond pulse power supply of electrochemical micromachining, including DC power supply, waveform generation circuit, rectifier and filter circuit，power amplification and rapid protection circuit. This power supply can generate 5MHz maximum frequency and square wave of 100ns pulse width, stably. The voltage ranges from 0V to 10V, and duty ratio ranges from 0.1 to 0.5, continuously.
