Abstract
An inspecting ECUand a GD substrateare connected to an inverter circuitfor converting a power to be supplied from a voltage sourceand outputting the converted power to a motor, and switch a conducting state of each of the elements in the inverter circuit. A conducting state of the element is switched in accordance with a driving condition for inspection corresponding to a whole active region of the element in a state that an inspecting loadis connected to the inverter circuit. A phase current flowing in the element and a voltage between terminals of the element through a voltage detectorand a current detectorare detected to obtain a correlation of an ON time of the element and a phase current value based on the current and the voltage which are detected.
