METHOD AND APPARATUS FOR CONTROLLING AN ALTERNATING CURRENT MACHINE

摘要

In one example embodiment, a device for controlling an alternating current (AC) machine is disclosed. The device includes a processor configured to determine a plurality of instantaneous voltages corresponding to a plurality of phase voltages of an inverter, the inverter driving the AC machine. The processor is further configured to determine an actual line-to-line voltage of the inverter based on the plurality of instantaneous voltages. The processor is further configured to determine a terminal voltage feedback for controlling the AC machine, based on the determined actual line-to-line voltage and a terminal voltage threshold.
