摘要： An electric power conversion device 1 has a first operation mode and a second operation mode. The first operation mode is of converting DC power received from a first terminal 11 into DC power having a desired voltage to be output to a second terminal 12. The second operation mode is of converting DC power received from the second terminal 12 into DC power having a desired voltage to be output to the first terminal 11. A switching section 50 is configured to, in the first operation mode, be turned on to cause short-circuiting between both ends of a capacitor 52 of a rectifying circuit 5, and, in the second operation mode, be turned off. Accordingly, a first conversion part 31 is configured to, in the first operation mode, supply DC power, received from the first terminal 11, from a first winding 21 to a second conversion part 32 through a conversion circuit 4, and, in the second operation mode, output to the first terminal 11 a voltage obtained by adding an output voltage of the rectifying circuit 5 to an output voltage of the conversion circuit 4. Therefore, it is possible to bidirectionally boost electric power while using a transformer.

摘要： A switching circuit is configured to switch on/off a current that flows through a resonance circuit constituted by a primary winding of a transformer, a capacitance element, and an inductor that are connected in series. Electric power that is induced in a secondary winding of the transformer is rectified by a rectifier circuit. A switch is connected in parallel with the capacitance element. A control unit is configured to control the switching circuit and the switch. The control unit is configured to select a first operation in which an operation frequency of the switching circuit is controlled by switching off the switch, and select a second operation in which a period during which a current flows from the switching circuit to the primary winding of the transformer is controlled by switching on the switch.
