PROBLEM TO BE SOLVED: To reduce the current flowing out to the outside further effectively in a power conversion device.SOLUTION: In a power conversion device, there is provided a push pull circuit (81) through which a compensation current (Ic) cancelling a leakage current (Ia) flows. In the push pull circuit (81), a first transistor (Tr1) and a second transistor (Tr2) are connected in series, and there are provided a first diode (D1) connected in reverse-parallel with the first transistor (Tr1), a second diode (D2) connected in reverse-parallel with the second transistor (Tr2), a third diode (D3) for preventing the current from flowing to a converter circuit (10), and a fourth diode (D4) for preventing the current from flowing toward a middle point (M2) between two transistors (Tr1, Tr2).SELECTED DRAWING: Figure 1 |
