Jumping after every move only to find it was normal zig zag movements and their stoploss get hit frequently 每一次波動中跳進跳出,結(jié)果發(fā)現(xiàn)只是一個正常的價格來回運動,他們的止損總是頻繁的被打到。
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,由于采用變壓器移相多重化整流,在理論上可以實現(xiàn)曲折變壓器一次繞組中低于6m 1次諧波電流相互抵消( m為串聯(lián)單元個數(shù)) ;對于逆變電路,由于采用移相pwm控制方式,等效開關(guān)頻率提高m倍,因此輸出電壓接近正弦波,諧波含量較小。
