Pulse power supply is widely used in areas of industrial production. A high efficiency high power  power supply is badly needed in mass production. And the parameter of a power supply  such as: efficiency, power volume ,power factor ,and reliability is very important. In this paper a 20Kw pulse power supply is proposed, designed ,and implemented. The system is made up of two stages. First stage is dual ZVT-Buck converter controlled by DSP. Second stage is Full Bridge DC/DC converter controlled by analog devices. Both stage is voltage closed-loop control with over current protection .And output pulse frequency is 20-50Khz,voltage level is 200-1000V,and pulse width is 0-100% changeable. Stability and efficiency of the system is proven by the experimental results.
