摘要：

Harmonic based phase-shifted control (HPSC) is a novel power control method for wireless power transmission, which adopts harmonics to transmit power it overcomes the poor efficiency problem of traditional phase shift control at light load condition. The mathematical model of inductive coupling power transfer (ICPT) considering the harmonics is built, the variation of output power characteristics at different switching frequency and phase angle is analyzed, and the harmonic switching method considering the inverter dead time is studied also. Harmonic current average detection method is put forward for the primary current control. At last, the primary current closed-loop control strategy based on harmonic phase-shifted control is researched and realized. Both simulation and experiment verify the effectiveness of the closed-loop control based on harmonic phase-shifted control. It can not only effectively improve the transmission efficiency of ICPT under light load, but also has better control characteristics. © 2018, Electrical Technology Press Co. Ltd.
