| Abstract: | This paper presents a single ended class-E soft switch inverter with IGBT as its switching component and analyzes its work circumstances.The performance parameters of the system are given with 6kW output power at 20kHz.This inverter uses series connected IGBTs as the switch in order to raise the voltage capacity.The analysis based on this class-E is given about the problem of voltage-sharing on its series connected IGBTs when their driving signals are not in-phase and the solution is also presented.In the end the simulative and experimental results are given. |
