Abstract
Cascade multilevel inverter was the most suitable inverter topology for the environment in high voltage and large power capacity.In this paper,we discussed the carrier phase shifting sinusoidal pulse width modulation（CPS-SPWM） based on that topology at first.And then how the DC capacitor unbalancing effect the output of cascaded multilevel inverter based on CPS-SPWM have been researched.At last simulations and experimentations are applied to research the inverter＇s output characteristic.The results of the simulations and experiments are matched with the calculation well.This paper ends with a conclusion that the cascaded multilevel inverter based on CPS-SPWM can not only improve switch frequency but also shows good ability of resisting dc side voltage fluctuation interference.关键词
