Abstract

Matrix converters (MC) enable direct AC-to-AC power conversion without large DC-link electrolytic capacitors and have been applied to various wireless power transfer (WPT) systems. However, traditional MC-based WPT systems suffer from commutation problems, requiring additional switching strategies to ensure safe operation, which increases the control complexity. To solve this problem, this paper proposes a novel three-phase wireless electric vehicle (EV) charging system based on MC. First, the three-phase AC voltage generated by the MC is directly used to drive the three-phase LCC-compensated WPT circuit, which eliminates the bulky short-life DC-bus capacitor and provides a compact rotational magnetic field. Furthermore, a dedicated modulation method is proposed to realize the frequency coordination of the MC stage and the WPT stage. Accordingly, the system can operate safely without additional commutation strategy. Finally, finite element simulations and circuit simulations are used to verify the analysis and prove the effectiveness of the proposed system. © 2023 IEEE.
