PROBLEM TO BE SOLVED: To provide a power conversion device that allows reducing turn-off loss with a more simplified circuit configuration.SOLUTION: A series circuit of a diode Da1, capacitors Ca1 and Ca2, and a diode Da2 is connected in parallel to a series circuit of switching elements S2 and S1. A common connection point between the capacitors Ca1 and Ca2 is connected to an emitter of the switching element S2. A series circuit of a switching element Sa1 and a diode Da3 is connected between a cathode of the diode Da1 and a cathode of the diode Da2. A series circuit of a diode Da4 and a switching element Sa2 is connected between an anode of the diode Da1 and the ground. A reactor La1 is connected between a source of the switching element Sa1 and a drain of the switching element Sa2. |
