Optimized design and sizing of wireless magnetic coupling stage for electric vehicle to grid V2G charging station

Inductive power transfer systems have attracted a lot of attention for wireless charging of electric vehicles due to its simplicity and ease of use. But because of the wireless transmission, it faces certain significant issues including leakage inductance and power loss. This paper offers a ground-breaking contribution to the development of inductive power transfer (IPT) systems intended for wireless electric vehicle (EV) charging by addressing the critical problem of power losses brought on by leakage inductance. This work meticulously examines the subtleties of leakage-induced losses using an advanced mathematical modeling tool, providing the groundwork for an innovative design approach. This approach yields development of output voltage formula that is stable and independent of load. This is a huge advancement that ensures EV wireless charging with dependability and efficiency never seen before. To assess the proposed methodology MATLAB/Simulink software is used and it showcase an outstanding a high DC-DC charging efficiency of up to 98%. The proposed methodology is tested for a 13 cm transmission range and is meant to allow for the transmission of 2.8 kW power.
