| Abstract: | 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 cancellation 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. |
