摘      要：正In this paper,an analysis is given to the topology of cascaded seven-level *** its simulation model is set up. On the other hand,several carrier control strategies are discussed,modeled and applied for the control of this multilevel inverter respectively,including phase disposition,phase opposition disposition and alternative phase opposition *** the switching control signals are properly produced according to the working principle of this inverter ***,the simulation models of the total system are set up respectively and the demanded experiments are carried *** results have verified the feasibility and easy realization of multi-carrier control strategies for this multi-level ***,these several multi-carrier control strategies are analyzed and compared in *** some useful conclusions are obtained with spectrum analysis *** lay good foundations for future researches.
