摘　　要：多电平变换器的调制策略与其主电路拓扑密切相关.基于3种多电平变换器的拓扑特点,给出了一种混合级联多电平变换器,分析了它的几种调制策略和频谱特性,并进行了电路仿真.仿真验证了结果的正确性。Modulation techniques of multilevel converters are closely related to its main circuit topology. A new hybrid cascade multilevel converter was presented in terms of the features of three types of multilevel converters, its several modulation skills and their spectral characteristics were analyzed, and the spectrum expression of continuous modulation was given as well. Simulation results show the validity of the analysis.
