Abstract
This paper proposes a new robust control technique for single-phase boost high-power-factor rectifiers. The proposed circuit significantly improves the dynamic response of the converter to load steps without the need of a high crossover frequency of the voltage loop, so that a low distortion of the input current is easily achieved. A 250-W power-factor-correction rectifier with the proposed control scheme has been designed and implemented, validating the concept both analytically and experimentally.
