摘要

感应耦合式无线电能传输(ICPT)的特点是短距离、大功率,适用于电动汽车无线充电。松耦合变压器作为ICPT核心器件,存在漏感大、激磁电感小的问题,需匹配补偿电容,提高输出功率和传输效率。通过改变误差系数,反映初、次级线圈漏感、激磁电感或补偿电容等电路参数变化,分析参数变化对S/SP补偿拓扑能效特性的敏感度,仿真和实验验证了分析的可行性。
        Inductively coupled wireless power transmission(ICPT)is characterized by short distance and high power,which is suitable for electric vehicles wireless charging.Loosely coupling transformer is the core of ICPT,has the problems of large leakage inductance and small magnetizing inductance.It needs to match the compensation capacitor to improve the output power and transmission efficiency.By changing the error coefficient,the changes of the circuit parameters such as the leakage inductance, the magnetizing inductance or the compensation capacitance are reflected,and the sensitivity of the parameter changes to the S/SP compensation topology is analyzed.The feasibility of the analysis is verified by simulation and experiment.
