Claim 10:
11. The power conversion circuit according to claim 9, wherein when four of the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch and the eighth switch are turned on at a switching frequency, the power conversion circuit is equivalent to a first resonant branch and a second resonant branch, wherein a first resonant frequency of the first resonant branch, a second resonant frequency second resonant branch and the switching frequency are equal, and a current flowing through each of the first winding, the second winding and the third winding is obtained by superposing a magnetized current through an equivalent magnetized inductor of the transformer and a sinusoidal current.
