| 摘 要： | 就一款主、副边互感线圈均为串联谐振感应耦合的电动汽车无线充电原理电路进行了深入分析，经对电动汽车的蓄电池电压与输入交流电源电压之比的优化，得出了它在稳态工作时电路的输出功率、传输效率与电路参数的关系，并得到了与互感线圈对应的补偿电容上的电压与输入交流电源电压、蓄电池电压及互感线圈互感量间的关系。通过仿真，对以上结果进行了验证，此结果可以为电动汽车在行进中充电打下基础。

| Abstract: | The wireless charging circuit of electric vehicles , whose primary and secondary side mutual in-ductance coil are both series resonant inductive coupling , is deeply analyzed .And the relationship between the output power , the transmission efficiency and the circuit parameters is concluded when it is in the steady state . Moreover , the relationship is concluded between the voltages of the compensation capacitor corresponding to the mutual inductance coil , AC supply and battery and the mutual inductance by means of optimizing the electric ve -hicle battery voltage and AC supply voltage ratio .Furthermore , all the results are verified by simulation , which may lay a foundation for electric vehicles charging while the vehicle is moving . |
