碩士 === 輔仁大學 === 電子工程學系 === 92 === A high voltage power supply applied to the traveling wave tube (TWT) is proposed in this paper. A Buck current-fed full bridge converter is used to reduce the effect of leakage inductances of high voltage transformer for improving the performance. The switching frequency of the converter is chosen at 100 kHz to reduce the size and weight of power supply. The transformer windings utilize 19 kV insulation wire. The high voltage output rectifier and double voltage multiplier provided the need for multiple high voltage outputs for cathode, collector-1, collector-2 of the TWT, respectively. This paper mentioned the simply scheme to develop and design the high voltage power supply. Finally, computer simulation and experimental results of laboratory prototype with 100 kHz、10 kV and 1 kW output are presented to demonstrate the feasibility of circuit topology.
