PROBLEM TO BE SOLVED: To provide a modified half-bridge type inverter device with the suppressed ripple current of an electrolytic capacitor for two inductive loads. SOLUTION: A rectifying power supply 10 which rectifies voltage of an AC power supply 11 is provided. A smoothing capacitor 20 which smoothes voltage of the rectifying power supply 10 is provided. A switching circuit to which voltage of the smoothing capacitor 20 is applied and which includes a 1st switching device 31 and a 2nd switching device 32 which are connected in forward series to each other and controlled so as to be turned on and off alternately is provided. A 1st flywheel diode 38 is connected in reverse-parallel to the 1st switching device 31 and a 2nd flywheel diode 39 is connected in reverse-parallel to the 2nd switching device 32. A 1st arm capacitor 51 is connected in parallel to the 1st switching device 31 via a 1st inductive load 41 and a 2nd arm capacitor 52 is connected in parallel to the 2nd switching device 32 via a 2nd inductive load 42. |
