Claim:
1. A method comprising: initiating, via a processor, one or more tests on a motor drive comprising a rectifier and an inverter electrically coupled to each other; executing, via the processor, voltage line sensing in order to create a phase-locked loop that syncs an input power of a power grid with an output power from the inverter before the one or more tests are run; receiving, via the processor, a desired active power (P) and a desired reactive power (Q) associated with the one or more tests on the motor drive; determining, via the processor, one or more gate drive signals to provide to a first set of switches in the rectifier, a second set of switches in the inverter, or a combination thereof, based on the desired P and Q; transmitting the one or more gate drive signals from the processor to the rectifier, the inverter, or the combination thereof; and operating the rectifier, the inverter, or the combination thereof, under a simulated load that corresponds to the desired P and Q based on the gate drive signals.
