Abstract

A simple, modified, DC rail soft-switched quasi-resonant circuit is proposed for a 400 Hz voltage source inverter for aero-space application. The proposed soft-switched topology consists of two switches, a resonant inductor and two different capacitors of small size. The advantage of this topology is that the DC link voltage is clamped to the source voltage without any circulating energy. The circuit is analysed through the SABER simulator and the results from simulation have been reported. The experimental circuit is designed and tested for a simple R-L load and then connected to a voltage source inverter (VSI) operating under space vector modulation (SVM).
