Wireless power transfer system employing parallel buck converters as primary-side inverter

This paper presents a composite inverter circuit for Wireless Power Transfer (WPT) systems, addressing the limitations of reconfigurability in traditional inverters, and catering to the evolving demands of multi-port power converters. The proposed circuit consists of parallel-connected Buck converters, demonstrates versatility by seamlessly functioning as a DC source, or an inverter power source at the primary side of WPT systems. Simulation results conducted using PLECS software validate the proposed inverter's suitability for WPT systems. The circuit demonstrates comparable output performance to a multi-level bridge inverter capable of both voltage reduction and boost, also allowing for DC-DC module reuse in multi-port power electronic converters.
