摘要： A power supply circuit includes inductors, capacitors, and switching elements. Ports are electrically insulated from each other. Two switching elements are alternately switched, and two other switching elements are alternately switched. The inductors are wound such that a magnetic flux is generated in the same direction when a phase difference between the switchings of the switching elements is zero. Duties of the switchings of the switching elements are changed equally, and a phase difference between the switchings is changed.

摘要： A power converter includes first and second switching circuits 12 and 16, a primary winding T1 having both ends connected to the first switching circuit 12, a secondary winding T2 having both ends connected to the second switching circuit 16 and magnetically coupled with the secondary winding T2, and a reactor L having a first end connected to a center tap m of the primary winding T1. The first switching circuit 12 includes a full bridge having half bridges U and V connected in parallel, and diodes D1 and D2 each having one end connected to a common point. The diodes D1 and D2 each have the other end connected to one of two parallel connecting points of the full bridge. Input alternating-current voltage Vin is applied between a second end of the reactor L and the connecting point of the diodes D1 and D2.

摘要： There is provided an electric power conversion circuit system having a primary side electric power conversion circuit, a secondary side electric power conversion circuit, and a control circuit. The control circuit sets at least one of a half-bridge phase difference between a lower-left-arm transistor and a lower-right-arm transistor of the primary side electric power conversion circuit and a half-bridge phase difference of the secondary side electric power conversion circuit based on OFF periods of the primary side and secondary side electric power conversion circuits, dead-times of the primary side and secondary side electric power conversion circuits, and an amount of change of a power supply voltage so that a current in a non-transmission period of electric power is zero between the primary side and secondary side electric power conversion circuits.
