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 (S550) corresponding to a plurality of phase voltages of an inverter for driving the AC machine. The processor is further configured to determine an actual line-to-line voltage of the inverter (S554) based on the plurality of instantaneous voltages. The processor is further configured to determine a terminal voltage feedback or current for controlling the AC machine (e.g., S558 or, S559 and S560), based on the determined actual line-to-line voltage and a terminal voltage threshold. |
