abstract

  • Wireless Power Transfer Systems (WPTS) have emerged as a promising solution for Electric Vehicle (EV) charging, offering enhanced mobility and adaptability within microgrids. This paper proposes design considerations for ring and spiral circular coils in WPTS, addressing current issues and aiming for efficient EV charging. A detailed analytical estimation for inductive characteristics is provided for WPTS. Then, design optimization of the WPTS based on coil geometrical parameters and relative placement is proposed. COMSOL software is used to determine the inductive parameters accurately to validate theoretical analysis for our proposed 500W charging coils. Finally, the coupling coefficients of various coreless and cored charging pads are investigated with different geometric dimensions and coil alignments, with I-core being recommended to avoid bifurcation phenomena.
