Abstract:
A motor inverter includes an inverter circuit having a plurality of switching elements, a capacitor, a precharge closing an opening and closing part, a controller closing the opening and closing part in response to the “ON” operation of the operational switch, wherein when charge is accumulated in the capacitor until voltage of the capacitor reaches a predetermined voltage value capable of determining whether or not short circuiting occurs, the controller controls a switching operation of the switching elements, and a determiner determining whether or not short circuiting occurs based on at least one of current flowing in the inverter circuit and voltage of the capacitor when the controller controls the switching operation of the switching elements in a state that the electric charge is accumulated in the capacitor and the opening and closing part is opened.

Claim (Index 1):
A motor inverter comprising:\n an inverter circuit having a plurality of switching elements connected in bridge configuration, wherein the inverter circuit has an electric power input connected to a DC power supply and an output connected to multiphase windings of an electric motor, and wherein each phase winding of the electric motor is supplied with electric power by a switching operation of the switching elements to drive the electric motor; a capacitor connected to the electric power input of the inverter circuit in parallel with each other; a precharge circuit having an opening and closing part provided in a line through which electric charge is accumulated in the capacitor and connected to the DC power supply via an operational switch, wherein the precharge circuit precharges the capacitor in response an \u201cON\u201d operation of the operational switch before a main relay connected between the electric power input of the inverter circuit and the DC power supply is closed; a controller closing the opening and closing part in response to the \u201cON\u201d operation of the operational switch, wherein when charge is accumulated in the capacitor until voltage of the capacitor reaches a predetermined voltage value capable of determining whether or not short circuiting occurs, the controller controls the switching operation of the switching elements in a state that the opening and closing part is opened: and a determiner determining whether or not short circuiting occurs based on at least one of current flowing in the inverter circuit and voltage of the capacitor when the controller controls the switching operation of the switching elements in a state that the electric charge is accumulated in the capacitor and the opening and closing part is opened.
