Abstract

See full text

An inverter main circuit using high-side MOSFETS converts a power source voltage of a battery to an alternating current, and supplies the alternating current to a three-phase motor. A control circuit drives, via a high-side drive circuit and a low-side drive circuit, the MOSFETS. A charge pump circuit boosts the power source voltage to a charge pump voltage. A bootstrap circuit outputs a bootstrap voltage that is boosted by diodes and capacitors, which is then passed to a clamp circuit for clamping and outputting as a clamp voltage. Based on the supply of the charge pump voltage or the clamp voltage in response to a fluctuation of the power source voltage, a continuous circuit operation is provided while protecting the circuit in operation.
