There is provided an inverter circuit such that it is possible to reduce loss occurring in semiconductor elements when starting up. An inverter circuit 4 formed of a switching element Q1 and a switching element Q2 connected in series, and connected to both ends of a direct current power source series circuit 30 formed of a direct current power source Psp and a direct current power source Psn connected in series, and including an alternating current output terminal U connected to a connection point of the switching element Q1 and the switching element Q2, an alternating current output terminal V connected to a connection point of the direct current power source Psp and direct current power source Psn, a bidirectional switch element S1 of which one end is connected to the alternating current output terminal U and the other end is connected to a terminal R of an alternating current power source 1, and a bidirectional switch element S2 of which one end is connected to the alternating current output terminal U and the other end is connected to a terminal S of the alternating current power source 1, causes the bidirectional switch elements S1 and S2 to turn on and off when starting up. |
