Abstract This paper proposes a nonlinear current reference generation method based on peak factor(PF) to simulate various loads for AC power source burn-in test by power energy feedback load current simulator(PEFLCS). On this basis, for nonlinear load current reference riches harmonic, conventional P control could not guarantee zero steady state error in nonlinear load current reference tracking and have good dynamic characteristic of system in the same time, the compound controller contained P and repetitive controller is proposed. The difference effects to nonlinear load current between two different structures of the compound controller with P and repetitive controller in parallel connection and in series connection are compared. Simulation and experimental results on 2.2kV·A prototype testify that the compound controller in series connection in this paper can better track nonlinear load current reference and achieve the simulation of nonlinear load.

Key words： Peak factor current reference load current simulator repetition control nonlinear load
