PROBLEM TO BE SOLVED: To obtain an inverter apparatus with which a switching operation can be performed at a low cost and stably. SOLUTION: A switching signal Xa and a switching signal Yb which are generated by a microcomputer 22 and which are at a frequency f0 are input to an AND circuit 68 in a combining circuit 48. A switching signal Xb and a switching signal Ya are input to an AND circuit 70. Thereby, a switching signal U, Vg at a frequency 2f0 is output from the AND circuit 68, and a switching signal V, Ug at a frequency 2f0 is output drom the AND circuit 70. As a result, switching elements 43U, 42Ug, 42V, 42Vg are switched at a frequency which is higher than that which is output from the microcomputer. |
