This paper proposes a control method For three-phase voltage-source PWM rectifiers using only a single current sensor in the de-link, A PWM modulation strategy for reconstructing three phase currents from the de-link current is given. When 3 empty set input currents cannot he reconstructed, a method for modifying the switching state of the PWM rectifier and a method for the predictive state observer is proposed, Compensation of the 2 sampling delays is also included, and this method is combined with all of the experiments. performance differences between the two methods in a typical voltage source PWM rectifier are investigated experimentally.
