Complete Boost PFC Design and Analysis

In this tutorial video, we convert a dc-dc boost converter into a closed-loop boost PFC. Two control loops are used, average current control is performed on the inner loop with an outer voltage loop. The loop is closed in the analog, s-domain, along with a digital implementation in the z-domain. After the loops are closed the input impedance is determined. You will learn to use PSIM for the analysis of the converter and to use SmartCtrl to determine the controller parameters.
