Abstract

This paper develops a new series resonant (current resonant) DC link inverter with a voltage clamped circuit. The proposed circuit has a fixed pulse frequency operation. The fixed pulse frequency at 20-50 kHz enables the system to work without audible noise, and to involve the much smaller-sized DC inductance and output capacitors compared with hard-switched current source inverters. The proposed circuit has a voltage clamped circuit which could control the voltage stress of the switches. In this paper, explanations of the new circuit configuration, the simulation, design considerations, and some experimental results are included
