PROBLEM TO BE SOLVED: To provide an inverter apparatus in which the switching loss of a switch is reduced by using a simple circuit. SOLUTION: A switching circuit 5a at an inverter apparatus is composed of a first switch S1 and a second switch S2 , of a first reactor L1 and a second reactor L2 , of a first capacitor C1 and a second capacitor C2 and of a first diode to a sixth diode D1 to D4 , Dx1 , Dx2 . When the first and second switches S1 , S2 are turned off, a zero-voltage switching(ZVS) operation is performed. When the first and second switches S1 , S2 are turned on so as to delay a load, the ZVS operation is performed. When the load is advanced, a zero-current switching(ZCS) operation is performed. |
