Abstract
The specific harmonic analysis of bidirectional LCL-IPT system is presented in the paper. A mathematical model is built to obtain both current and power harmonic contents. The converter loss, devices properties, charging performance and harmonic power flow have been investigated to discuss the effect of harmonics on the system performance. Simulation and experiment results reveal that there are high harmonic currents in the system, which results in efficiency reduction and devices damage. The harmonic power flow is negligibly low compared to the fundamental.
