Abstract: A vehicle driving device includes an inverter which drives a motor. The inverter includes: a three-phase bridge circuit including a plurality of switching elements; a three-phase short circuit which short-circuits three phases of the motor via the three-phase bridge circuit; and a control circuit. The control circuit includes: a microprocessor which drives the three-phase bridge circuit; a malfunction notification circuit which outputs a malfunction notification signal when the microprocessor is malfunctioning; and a latch circuit which holds the malfunction notification signal outputted from the malfunction notification circuit. The control circuit outputs a three-phase short-circuit drive signal which drives the three-phase short circuit, based on the malfunction notification signal held by the latch circuit.

Abstract: An integrally-molded coil according to the present disclosure includes a coil portion and a resin portion. The resin portion is formed by molding a resin material having electrical insulation and thermal conductivity using the coil portion as an insert. The coil portion includes a coil main body and one or more pairs of leads each extending from the coil main body to an outside of the resin portion. An outer surface of the resin portion is applied with a surface treatment for imparting electrical conductivity, and is insulated from the one or more pairs of leads.
