摘要：
The classical four-coil magnetic resonance coupling wireless power transfer (MRC-WPT) system usually uses a SeriesSeries-Series-Series (SSSS) compensation network, while its input series resistance and load resistance are designed approximately. I It is a remarkable fact that the power loss of the input series resistance adversely affects the overall efficiency of the WPT system, but the absence of the resistance will lead to the input current surge when the four-coil system is detuned, which is not conducive to the stability of the security of the circuit system. With this aim in mind, an Inductance-CapacitanceCapacitance-Series-Series-Series (LCC-SSS) compensation network is proposed in this paper, which removes the input series resistance to improve the total efficiency on the premise of ensuring the reliability of the system. Relation between transmission efficiency, transmission power and parameters of LCC-SSS compensation network, the parametric calculation method of LCC compensation network is presented. Finally, the experimental results compare the transmission power and efficiency of the two compensation networks and verify the correctness of the LCC-SSS compensation network.
