| Abstract |
This paper shows that the large signal behavior of a popular family of high-power-factor ac-dc converters can be effectively controlled by a fast linear controller with periodic gains and feedforward of load power. The modeling process based on a dynamic power balance is described, together with the controller design procedure. An estimation scheme which deals with circuit parameter uncertainty is given, improving the robustness of the proposed controller. Simulations corroborating theoretical results are presented. |
