PROBLEM TO BE SOLVED: To provide a power conversion apparatus capable of reducing switching loss.SOLUTION: A first inverter part 20 includes SW elements 21 to 26 connected to one ends of coils 11 to 13 and is driven by a first power supply source 41. A second inverter part 30 includes SW elements 31 to 36 connected to the other ends of the coils 11 to 13 and is driven by a second power supply source 42. A first control signal generation part 61 controls an on/off operation of the SW elements 21 to 26 through PWM control based on a carrier wave and a first fundamental wave F1. A second control signal generation part 62 controls, on the basis of a second fundamental wave F2 whose phase is shifted by 180° with respect to the first fundamental wave F1, an on/off operation of the SW elements 31 to 36 so that the number of times of switching of the SW elements 31 to 36 is smaller than that of the SW elements 21 to 26. This makes it possible to reduce switching loss. |
