A Self-Controlled Power Factor Correction Single-Phase Boost Pre-Regulator

This paper presents a strategy for controlling the input current of a single-phase boost PFC (power factor corrector). A sample of the input voltage is not necessary since it is naturally used as the reference current. Besides this, the model presents few simplifications, therefore, being more complete, taking better advantage of the natural characteristics of the converter and obtaining similar results, when compared to classic control, by simply using a proportional compensator. Some of the advantages of this strategy include greater robustness and simplicity, less susceptibility to noise and a smoother turn-on characteristic
