Optimal Design of Resonant Network for 800 V Class 11.1 kW Wireless Power Transfer System with Double-Sided LCC Compensation Circuit

Electronics, Journal Year: 2025, Volume and Issue: 14(9), P. 1701 - 1701

Published: April 22, 2025

This study proposes an optimal resonant network design for 11.1 kW wireless power transfer (WPT) system with a double-sided LCC compensation circuit, targeting 800 V class battery applications. Conventional WPT circuit topologies and parameters specified in existing standards, such as SAE J2954, are unsuitable systems because they impose excessive voltage current stresses on the components. To address this, proposed focuses minimizing component while ensuring compliance output requirements charging. A switched capacitor technique is integrated into to dynamically adjust capacitance, enabling seamless adaptation constant current–constant charging profile. The feasibility of validated through simulations experiments, demonstrating input 400 VDC, range 560–820 rated capacity kW. Under conditions, achieves peak efficiency 95%, underscoring its practicality high-voltage electric vehicle

Resonance Capacitance Selection Method for Minimizing Leakage Magnetic Fields and Achieving Zero Phase Angles in Wireless Power Transfer Systems

Electronics, Journal Year: 2024, Volume and Issue: 13(21), P. 4188 - 4188

Published: Oct. 25, 2024

This study proposes a novel approach for selecting the resonance capacitance of wireless power transfer systems, aiming to achieve zero phase angle (ZPA) while simultaneously minimizing leakage magnetic field. The performance method is validated across two key topologies: series–series (S–S or SS) and double-sided inductor–capacitor–capacitor (LCC, LCC–LCC) topologies. By vector phasor sum coil currents, proposed effectively mitigates field leakage. further through mathematical derivations, simulations, experimental tests. results reveal that using select capacitances reduces by up 35.2% in SS topology 42.0% LCC topology. Furthermore, improves ZPA more than 20° both cases. These outcomes affirm effectiveness tuning approach.
