A Novel Dual CC-CV Output Wireless EV Charger With Minimal Dependency on Both Coil Coupling and Load Variation

Robust and efficient wireless EV charging requires load and coupling independent CC and CV modes. Existing literature focus either on CC or CV mode. The characteristics of the schemes which cater to both the modes are affected by load and coupling coefficient. In this paper, an improved dual output charger topology is proposed that is maximally independent from variations in coil coupling and load. Relevant analysis and simulation results are shown to validate the working of the proposed topology.
