Abstract

This paper presents an nonlinear load emulator for testing AC power supplies and power equipment with energy regeneration capability. The structure is based on back to back three-phase PWM voltage source inverter (VSI). To achieve power balance, an independent control strategy for both PWM VSI is proposed. Experimental results are presented to verify the emulator performance draining a linear and nonlinear current from an autotransformer and regenerating the energy to the utility grid.
