Abstract

In order to reduce harmonic component of inductively coupled power transfer (ICPT) system, this work proposes a two-channel ICPT system based on the harmonic of inverse injection which detects the harmonic component of fundamental wave channel by controlling the harmonic of inverse injection from harmonic channel. First, based on the transfer admittance model, each harmonic component in the fundamental wave channel is analyzed to determine the size and ordinal number of harmonic which needs to be eliminated. Then, the principle block diagram of the system is given. Accordingly, the harmonic channel should possess good constant current and frequency-selecting property. The resonance compensation topology of the harmonic channel is determined by making the comparative analysis of frequency-selecting property of LCCL and LCL. Finally, conditions of the selected harmonic elimination can be derived by optimizing the whole system parameter. Experiment shows that when parameter optimization is achieved, the novel ICPT system can offset the selected harmonic of output current of high-frequency inverter in the fundamental wave channel, achieving high-quality electric power transmission.
