Inverter apparatus and method of controlling inverter apparatus

Provided is an inverter apparatus (20) configured to switch a current winding to an optimal winding when a rotation speed of a rotor of an AC electric motor (40) is within a hysteresis region defined by first and second switch timings for switching a state of an armature winding between a first wind...

Zusammenfassung:	Provided is an inverter apparatus (20) configured to switch a current winding to an optimal winding when a rotation speed of a rotor of an AC electric motor (40) is within a hysteresis region defined by first and second switch timings for switching a state of an armature winding between a first winding and a second winding and when the current winding differs from the optimal winding.
