Control technique with fast response for power factor correction rectifiers

This paper proposes a new control technique for single-phase boost power-factor-correction rectifiers. The proposed circuit improves the dynamic response of the converter to load steps without the need of a high crossover frequency of the voltage loop. So a low distortion of the input current is easily achieved. A 200W power-factor correction rectifier with the proposed control scheme has been designed, simulated and implemented, validating the concept.
