Abstract
An object is to provide an inverter module capable of reducing installation space, and in summary, the inverter module comprises a switching element group provided in a mold package to convert a DC voltage into a three-phase pseudo AC voltage by switching, wherein resistors to detect voltages before and after a switch connected in serial to a DC power source are integrally molded into the mold package, and wherein there are provided pins to connect the resistors before and after the switch, and pins to output terminal voltages of the resistors.
