An LLC Based Single Stage Step Up AC to DC Resonant Converter without Boost Circuit for EV Charging With High Power Factor
Also Available Domains Electrical Vehicles
Objective
The main objective of this project is to develop a highly efficient, cost-effective, and simplified power conversion solution that integrates Power Factor Correction (PFC) and DC/DC conversion into a single stage, specifically designed for electric vehicle (EV) charging applications.
Abstract
This Project proposes a single-stage step-up ac/dc LLC resonant converter with a PFC function. The control of the LLC stage achieves PFC function and the first stage boost circuits in traditional PFCs are eliminated. As a result, boost circuit switching loss and related costs can also be eliminated. The resonant tank in the LLC stage achieves soft-switching to maintain a high conversion efficiency. A variable frequency control strategy is utilized in the LLC stage to realize the PFC function. Simulation were conducted through Matlab-Simulink to verify the feasibility of the proposed method.
Keywords: AC/DC converter, LLC resonant converter, power factor correction (PFC), zero voltage switching (ZVS).
