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.

摘要： A power supply system includes first and second DC power supplies and a power converter having first to fifth semiconductor elements and first and second reactors. The first and fourth semiconductor elements are electrically connected between a first node and a second node, and a first power line, respectively. Second and third switching elements are electrically connected between the first node and the second node, and a second power line, respectively. A fifth switching element is electrically connected between the first node and the second node. The first reactor is electrically connected in series with the first DC power supply, between the first node and the second power line. The second reactor is electrically connected in series with the second DC power supply, between the first power line and the second node.

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.
