DESIGN OF A POWER PROCESSING UNIT FOR SPACE ION ELECTRIC PROPULSION SYSTEM

The power supply unit is a one of the important equipment of space electric propulsion system.It is complicated power supply that composed many power supplies;provide high output power,high output voltage,and time sequence control.This paper is take ion electric propulsion power supply unit as an example,describing electric circuit design that provide 1 kW,the screen power supply output voltage arrive at 1000V,and gave the experiment the test of the electric circuit result.
