摘　　要：多重化电力变换器具有良好的输出特性,其有效开关频率高、波形质量好、动态响应快、冗余度高,在大容量电力变换器中占有优势。文章深入分析了一种变压器耦合串联型三相二重化电压源逆变器及其谐波特性,阐述了其物理意义,揭示了多重化后逆变器输出谐波的相位关系和对消规律。物理意义明确,易于理解。分析方法具有普遍性,可以应用于任意重化逆变器的谐波分析。The multiple power inverter has prefect output character. It prevailed in large capacity inverter with its inherent advantages of high efficient switching frequency, high quality output waveform, quick dynamic response and high redundancy. This paper thoroughly analyzed the harmonic character and its physical significance based on a three-phase dual series-connected voltage source inverter, analysis the phase relationships and canceUation law of the multiple inverter＇s output harmonic. The physical significance is definite and easy to understanding. With the universal analyse, the method can be applied to any multiple inverter＇s harmonic analysis.
