Abstract :
A large-signal average model for the controlled on-time boost power factor correction (PFC) circuit is developed and subsequently linearized resulting in a small-signal model for the PFC circuit. AC analyses are performed using the small-signal model, revealing new results on small-signal dynamics of the PFC circuit. The analysis results and model predictions are confirmed with experimental measurements on a 200 W prototype PFC circuit
