Abstract

An AC active load simulator is realized and tested which can simulate an AC load impedance excited by an AC voltage source. An interface circuit is designed to compute the simulated current waveform for the load-driver circuit according to the specified impedance network and the measured source frequency and voltage amplitude. Both inductive and capacitive loads can be simulated by adjusting the phase difference between the voltage and current waveforms. A software feedback control approach is employed to adjust the current amplitude for the purpose of maintaining the impedance value constant regardless of the variation of the source voltage amplitude
