Abstract
An inverter apparatus is composed of a power MOSFET having a source/drain connected to an output terminal, and a gate drive circuit driving a gate of the power MOSFET. The gate drive circuit includes a discharging path connected with the gate of the power MOSFET. The discharging path includes a set of serially-connected diodes which are forward-connected in a direction of a discharge current from the gate of the power MOSFET.
