摘要
感应电能传输(inductive power transfer,IPT)系统的耦合机构偏移造成耦合线圈互感变化,导致输出电压偏离额定值,影响系统的可用性。为此,提出一种基于串联补偿拓扑的电路参数优化方法,来提高系统在负荷变化和耦合机构偏移情况下电压增益的平稳性。最后,搭建了实验原型机来验证该方法的有效性,结果表明:系统参数优化后,当耦合线圈偏移时互感由47.5?H变化至66.6?H,交流侧负载由15?变化至25??时,电压增益波动范围为0.52～0.64,对应波动比例为10.3%,比理论波动值高0.3%。系统效率始终高于94.2%,且最高值达95.79%。
Misalignment between coupler of inductive power transfer(IPT) system causes fluctuant output voltage deviated from rated value, decreasing the availability of IPT.Therefore, this paper proposed a series-series(SS)compensated topology based parameter optimized method to improve the stability of voltage gain under various load and misalignment conditions. Finally, a prototype was set up to validate the performance of the proposed method, and experimental results indicate that the voltage gain is ranging from 0.52 to 0.64 with fluctuant ratio of 10.3% with the mutual inductance from 47.5?H to 66.6?H and AC load resister from15? to 25?. At the same time, the DC/DC efficiency of the overall system is no less than 94.2%, while the maximum efficiency is up to 95.79%.
