Modeling, analysis and simulation results regarding a power factor correction rectifier [articol]

Abstract

This paper proposes a new control technique for single-phase boost power-factor-correction (PFC) rectifiers that 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 100W power-factor correction rectifier with the proposed control scheme has been designed, simulated and implemented, validating the concept.
