Detuned Parameter Design for LCC-S Compensated Inductively Coupled Power Transfer with Wide Coupling Variation

Li, Weijie / Mei, Weiyao / Yuan, Quan / Miao, Chunhui / Zhang, Zhijie / Diao, Lijun

The output performance of inductively coupled power transfer (ICPT) system can be influenced by the variation of coupling conditions evidently. In order to keep the constant voltage output (CVO) characteristic under the wide coupling variation condition, a detuned parameter design method is proposed and analyzed in this paper. The principle of this parameter designing process is only adjusting the compensated capacitors in transmitting side, without the change of switching frequency and the design value of other resonant elements. Then, the effectiveness of the proposed approach is verified based on a simulation model of 50 kW operating at zero current switching (ZCS) condition in MATLAB. With different combinations of detuned compensation capacitors, the output voltage can be stable under different coupling coefficients, and the amplitude fluctuation of it can be restricted into 4.76%.
