Abstract
A transformer emulator includes a DC bus, a first power electronics converter circuit having a DC port coupled to the DC bus, a second power electronics converter circuit having a DC port coupled to the DC bus, and a third power electronics converter circuit having DC port coupled to the DC bus. The transformer emulator further includes a control circuit configured to control the first, second and third power electronics converter circuits to emulate a transformer having a first port corresponding to an AC port of the first power electronics converter circuit and a second port corresponding to an AC port of the second power electronics converter circuit. The control circuit is configured to control the first and second power electronics converter circuits to emulate a voltage transformation of the transformer and to control the third power electronics converter circuit to emulate a loss of the transformer.
