Abstract
Electric Vehicles are a suitable solution for sustainability in transportation applications. The era of wireless power transfer in free space began with the evolution of Tesla coils being energized by microwaves. High-frequency inverters act as the electrifier for high power wireless charging. DC-DC converters play an indispensable role in converting the AC power from a high-frequency inverter to DC power to the battery or the energy storage system in the vehicle. The converter's design will be based on the battery and energy storage system's charging conditions, constant current, and constant voltage operating conditions and the State of Charge (SOC). The non-linearity in the system can be implemented with a sliding mode control. The topology of the converters with the hybridization of the energy storage systems is also discussed. The models are evaluated with simulation in MATLAB with the control system toolbox. The energy storage system includes batteries and supercapacitors. The concept of bi-directional converters for regenerative braking mode constraints is also considered for digital closed-loop implementation. The chapter comprises topologies of DC-DC converters’ roles for wireless charging of batteries, digital controls with parameter evaluation, and sliding mode controls for the system's dynamic control.
