Abstract
Methods and apparatus provide for: a first DC bus operating to support a first DC voltage potential and for connecting to a DC input of a motor driver inverter circuit; a motor emulator circuit operating to emulate a polyphase motor and including polyphase output terminals for connecting to a polyphase output of the motor driver inverter circuit; a second DC bus operating to support a second DC voltage potential to a DC input of the motor emulator circuit; and a bi-directional DC-DC power supply coupled between the first and second DC busses, and operating to both: (i) add voltage potential to the first DC voltage potential to produce the higher, second DC voltage potential on the second DC bus, and (ii) subtract voltage potential from the second DC voltage potential to produce the lower, first DC voltage potential on the first DC bus.
