Design and Implement of a High-Power Pulse Power Supply Based on Fly-Back Charging

In order to implement a high-power pulse power supply of which the voltage and current is up to −75kV/40A, this paper adopt the method of fly-back charging. Firstly, it introduces the advantage and principle of fly-back charging. Then, gives the design scheme and calculate parameters in detail. Lastly, provides the experiment results of the pulse power supply. The results indicate that the performance of the power supply can satisfy the requirement of the pulse power supply, and the power supply has high precision and reliability. It is helpful for related engineering design as reference.
