摘要

本文对不同拓扑结构下线圈系统的损耗进行了解析计算。不同的系统拓扑结构一方面包括串行补偿线圈,另一方面包括并联补偿线圈。根据负载电阻、质量因数、磁耦合、设计频率和次级侧电感的不同,每侧各有一个电容的四种可能组合都有不同的效率解决方案。计算只考虑基频,从而忽略了逆变器和整流器的谐波和损耗。最后,根据不同的负载电阻对不同的拓扑结构进行了比较,并指出了效率最高的工作点。

Contactless Energy Transfer - Analytical Calculation of the Coil Systems’ Efficiencies for Different Topologies
In this paper, the losses of the coil system for different system topologies are analytically calculated. The different system topologies comprise on the one hand serial compensated coils and on the other hand parallel compensated coils. Each of the four possible combinations with one capacitor on each side has a different solution for the efficiency depending on the load resistance, the quality factor, the magnetic coupling, the design frequency and the secondary side inductance. The calculation considers only the fundamental frequency, thus harmonics as well as losses in inverter and rectifier are neglected. The paper concludes with a comparison of the different topologies based on a varying load resistance and points out the operating point with maximum efficiency.
