A high voltage, high power pulsed TWT power supply for space application

Abstract

The power supply presented is used to operate a pulsed TWT in a microwave experiment, which will be flown during the first Spacelab (Spaceshuttle) mission. Various high voltages up to 10 KV at a pulsed power of 9 KW are provided by the supply. The design features of power conversion, high voltage insulation, pulse generation and protection circuitry are described and test results are presented.
