Abstract
The voltage type inverter is widely used in life.Aiming at shortages of traditional two-level inverter such as large switch loss and output harmonic, a set of reverse-coupled inductors is cross-connected in parallel betw een tw o arms of a conventional tw olevel full-bridge inverter, and then this paper proposes a kind of single phase three-level half-bridge inverter topology.This topology is capable of clamping out a zero level and outputting three-level by using reverse-coupled inductors in several certain operating modes.Compared w ith traditional three-level inverter circuit, this topology uses few er pow er sw itches w hich means more simple control.Therefore, the paper analyzes and discusses different operating modes of the new single-phase three-level inverter topology and establishes M ATLAB/Simulink simulation model for verification.The simulation results are consistent w ith discussion results, w hich indicates correctness and effectiveness of this new inverter topology.关键词
