| Abstract: | The modulating strategies of multilevel converters are closely related to its main circuit topology. In this paper, the topology characteristics of several multilevel converters are compared and discussed, and a hybrid multilevel converter are recommended. Several modulating strategies and spectrum characteristics are analyzed. The spectrum expression of continuous modulation is given. Simulation results are presented to discuss their advantages and disadvantages, to certify the validity of the result. In the end, several useful conclusions are summarized |
