An Improved Space Vector Pulse Width Modulation Algorithm of Multilevel Inverter

Jie Ma

Abstract

The problem of voltage unbalance of neutral point affects the reliability of the inverter and its electric drive system.This paper presents an improved SVPWM algorithm,and analyzed its principle in detail.Finally,the effectiveness of proposed algorithm is confirmed by experiment results based on Matlab/simulink.
