A high-voltage pulse power unit is presented, which can output multiple bipolar asymmetric pulse waveforms. It is made according to the characteristics and requirements of a novel surface treatment process and on the basis of the analysis of and comparison with the existing pulse realizing circuit. With the power unit, amplitude, frequency and duty radio of pulses can be adjusted continuously within a given range. Therefore, it is very suitable for technologists to explore optimal technology parameters. The clamping action of the pulse realizing circuit can effectively relieve the voltage applied on the power switch transistor so that the reliability and service life of the pulse power unit are increased.
