| description | To provide a power conversion device capable of reducing energy loss.SOLUTION: A power conversion device according to one embodiment of the disclosure includes a first power terminal, a switching circuit including first and second switching elements connected in series through a connection node, a trans, a rectifier circuit, a filter circuit, a second power terminal, a control circuit, a voltage generation circuit, and a driving unit including a diode, a capacitor, and a driving circuit that drives the first switching element using the voltage between both ends of the capacitor as a power source voltage. The control circuit repeatedly changes the operation state of the switching circuit in the order of a first operation state in which the first and second switching elements are kept off, a second operation state in which the first switching element is kept off and the second switching element performs a switching operation, and a third operation state in which the first and second switching elements perform the switching operation.SELECTED DRAWING: Figure 10
