The article presents the design and experimental results of a isolating 80 kV high-voltage high-power switching power supply.This power supply isolates DC80 kV voltage,responses less than 3 ms,and has the maximum output power of 90 kW.In order to meet the requirements of rapid response and small tipple,the main circuit topology is optimized.Highfrequency transformer is used to isolate the DC80 kV high-voltage.After analyzing the relationship between the transformer leakage inductance and duty cycle loss,the transformer DC equivalent circuit is given.Experiment shows that the power supply works stable with good performance.
