Abstract

This work presents detailed small-signal-modeling and closed-loop controller design of novel Cuk-based PFC converter for on-board EV charger. Since the converter is designed to operate in discontinuous conduction mode (DCM) for attaining power factor correction (PFC) naturally on the input side. Thus, only the output voltage sensing is required as the input voltage and current sensing is not necessary. Thereby, making the operation of the converter less-costly, reliable, and intensifying the robustness towards higher frequency noise. The control strategy is straightforward requiring one control loop and sensor. This article describes the complete derivation of control-to-output transfer function along with optimal selection of control parameters. Finally, to validate the controller design, simulation and hardware results are provided.
