Study on Power Loss of High Power Three-Level Converter

Abstract: Based on studying the running elements of three-level converter, the paper proposes a simple and accurate method of computing conduction and switching loss for three-level converter system. Analyses the factor of conduction and switching loss each other，also builds the experimentation of high power three-level converter and introduces a new double-fed experiment method to validating the accuracy of model.
