Claim 0:
1. A motor emulator for an Inverter Under Test (IUT), comprising:
a voltage following inverter configured to cancel an output voltage of the IUT at least partially; and
an output current control unit configured to control an output current of the IUT based on the output voltage of the IUT and an estimated current of an emulation target motor,
wherein the voltage following inverter includes:
a DC terminal voltage source;
a first switching unit connected to the DC terminal voltage source in parallel and electrically connected to an output terminal of the IUT; and
a first switching control unit configured to control switching of the first switching unit based on the output voltage of the IUT and a predetermined threshold voltage.
