As a result of employing multilevel phase - shifted method with zig zag connection in transformer secondary, in the primary the current harmonics their orders are lower than 6m 1 are eliminated ( m is the number of power cell each phase ). in the inverter side because of using pulse shifting pwm control, the equivalent switch frequency of output is m times as high as one h - bridge, so the output voltage waveform of the inverter is near sine with less harmonics
對于整流電路，由於採用變壓器移相多重化整流，在理論上可以實現曲折變壓器一次繞組中低於6m 1次諧波電流相互抵消（ m為串聯單元個數） ；對于逆變電路，由於採用移相pwm控制方式，等效開關頻率提高m倍，因此輸出電壓接近正弦波，諧波含量較小。
