摘　　要：基于阶梯波调制法和复合调制法,量化分析了混合级联型多电平变换器(HybridCascadeMultilevelConverter,简称HCMC)输出电压波形的谐波分布,推导出其谐波解析表达式。由此指出,阶梯波调制法和复合调制法各自的优越性,为使用少量模块单元实现尽可能多的电平数的HCMC提供了理论依据。实验结果验证了该谐波分析结论的正确性。Based on the staircase modulation method and hybrid modulation method in hybrid cascade multilevel converter,this paper analyzed the harmonic spectrum of output voltage respectively,and then derived the harmonic expressions.The advantages of two control strategies were pointed out,which are useful in designing and applying hybrid multilevel converter in future.Finally, the experimental results showed good agreement with the harmonic analysis.
