Abstract

Abstract: This research explores a double-sided LCC compensation network's utilization in an inductively coupled wireless power transfer (WPT) system for electric car charging applications and its wireless power transfer tuning procedure (WPT). A wireless power transmission system is offered with a double-sided LCC compensating network. The compensation circuit is crucial because it may be used to adjust the system's resonance frequency, lower reactive power in the power electronics converter, and boost the efficiency and capability of transferred power. The proposed architecture and its tuning technique allow the system to operate at a constant switching frequency since the resonant frequency is unaffected by the coupling coefficient between the two coils and is also independent of the load status. Also, it has been discovered that the corrected receiving coil inductance is a useful tuning parameter for ensuring the primary side zero voltage switching (ZVS) operation.
