Abstract: In order to meet the requirement of auxiliary heating system such as electronic cyclotron 
resonance heating, lower hybrid current driving and neutral beam injection, high voltage power supplies based on 
pulse step modulate technology have been designed to provide high voltage to klystron, gyrotron and neutral 
beam ion source. A high voltage power supply for electronic cyclotron system is analyzed. Multi-winding high 
voltage isolation transformers, solid-state high voltage modulators and a control system are designed in the high 
voltage power supply. A control algorithm is obtained, which makes it easy to adjust the output of high voltage, 
the rising and falling time of high voltage. The experimental results are given to verify the power protection ability, 
the maneuverability and practicability of the power control algorithm. The high voltage power supply meets not 
only the requirements of fast protection of load, but also the design requirements such as the stability of power 
supply.
