Double Outputs Resonant-based Wireless Charger for Electric Vehicle and Robotic Applications

The work presented in this paper deals with power electronics topologies for electric vehicle chargers and more generally in mobility applications. The paper proposes a dual output wireless charger, a 120V/60Hz AC and 24V DC output, operating at a resonant frequency of 75 kHz. Considering that the targeted applications of the charger are intended to operate with a voltage of 120V/60Hz, the designed wireless charger will have to be powered from a standard 120V/60Hz outlet. The maximum current drawn by the load will be limited to 20A, a nominal apparent power of 2.4 kVA is then defined according to SAE J2954. This power belongs to class 1 as defined by this standard. All active and passive components are designed on the basis of a charger defined by the SAE J2954 standard. To validate the feasibility, the proposed topology is modelled and then simulated on MATLAB Simulink to show its performance and analyse its limits.
