PROBLEM TO BE SOLVED: To provide an inverter in which an inverter housing chamber can be made small And which can be miniaturized. SOLUTION: An inverter is provided with a heat sink plate 11 which constitutes a heat sink, with an inverter case 62 which forms an inverter housing chamber 14, with a control circuit board 64 which is fixed to the top wall part 62a of the inverter case 62 and which outputs a pulse-width modulation signal and with a bridge circuit 18 which is housed in the inverter housing chamber 14, which is fixed to the heat sink plate 11 and which generates a phase current on the basis of the pulse-width modulation signal to be output from the control circuit board 64. Since the control circuit board 64 is fixed to the top wall part 62a of the inverter case 62, it is not required to arrange and install a bracket at the inverter housing chamber 14. Consequently, the inverter housing chamber 14 can be made small, and the inverter apparatus can be miniaturized. |
