Abstract
A vehicle inverter device for driving an electric motor using a vehicle electric power source. The vehicle inverter device includes an input terminal, a filter circuit including a capacitor, an inverter circuit, a positive bus bar, a negative bus bar, a control circuit, an upper arm ground line, and a low voltage electric power source circuit. The control circuit causes only a lower arm switching element to be in an on-state and electrically connects the control circuit and the negative bus bar through the upper arm ground line when a direct current electric power is supplied from the low-voltage electric power source circuit under a condition where a direct current electric power is not inputted to the input terminal.
