Abstract

The topology of three-phase three-level neutral-point-clamped inverter was presented,with the merit of the three-level inverter.Aiming at the control features of inverter analysed and the SVPWM(Space Vector Pulse Width Modulation)algorithm was chosen for the flexibility superiority and Simulink tools was used to build a simulation of SVPWM control algorithm.This algorithm was applied to the asynchronous motor.The simulation results show that AC current has a good sinusoidal wave and sound sector judgment,this novel method offers a new approach for designing and debugging.
