Inverter device and motor driving device provided with inrush current prevention circuit

摘要

An inverter device and a motor driving device are arranged to have an inrush current prevention circuit for preventing an inrush current from flowing into a smoothing circuit when the power is turned on. The inrush current prevention circuit includes a current limiter for limiting the inrush current, a plurality of semiconductor switching elements, and an inrush current prevention circuit driving-circuit for driving the plurality of semiconductor switching elements, the semiconductor switching elements being connected together.
