These topologies of inverters are composed of two bi - boost dc / dc converters, they are symmetry. so whole circuit turn into four - quadrant converters, we can control every power mosfet on or off. then we can get sine wave with direct current polarization at the left, at the same we also can get sine wave with direct current polarization phase contrast 180 compared of the left at the right
這類逆變器由左右二個雙向boostdc / dc變換器構成,左右二邊是對稱的,所以整個電路構成了一個四象限變換器,我們可以恰當控制各功率管的開、關,使左邊的兩象限dc / dc變換器輸出一個帶直流偏置的正弦波,使右邊的兩象限dc / dc變換器輸出一個相差180度帶同樣直流偏置的正弦波形,這樣,負載zl上的電壓是左、右兩個dc / dc變換器電壓的差動輸出,正好可以消掉直流偏置,最終在負載r1上得到的就是正弦波。
