ABSTRACT:
An inverter apparatus and an inverter controlling method for judging a P-N impedance fault, a ground fault or a transistor fault by respective predetermined judging circuits according to either a voltage developed across a smoothing capacitor or the rate of change in the voltage while the smoothing capacitor is being charged. The charging of the capacitor is carried out via a resistor circuit or before the resistor circuit is short-circuited by a relay.
