Abstract

This paper proposes a novel dual-frequency dual-channel wireless power transfer (WPT) system that enables closed-loop power control without communication devices or parameter estimation. A third-harmonic resonant channel is incorporated into the traditional Series- Series (S-S) compensation WPT to achieve power regulation and wide-range zero-voltage switching (ZVS) by the third-harmonic current phase information feedback control strategy. The third-harmonic current simultaneously contributes to partial power transmission, phase information feedback, and the enhancement of soft-switching performance across all switches, particularly under medium-low power condition (30 %–70 % rated power). A synchronization control method is introduced, allowing the primary and secondary sides to achieve coordinated regulation without signal synchronization hardware. Experimental results from a 1.6 kW prototype demonstrate a wide ZVS range of D = 0.1–0.5 and closed-loop power control. The system achieves a peak efficiency of 95.68 %, while maintaining above 93 % efficiency when the transmission power is within 40 %–100 % of the rated power.
