摘　　要：针对无线电力传输系统效率低、功率因数低的问题,设计了一款数字家电用无线电力传输电源。该电源的主电路由开关输入网络、谐振耦合网络和高频整流网络三部分组成。其中谐振耦合网络的原、副边线圈采用SP补偿法。采用互感模型法对主电路进行了分析,给出了主电路的等效电路图。推导了电压增益,并给出了电压增益随谐振网络参数变化的曲线。制作了一个额定功率为1000W的样机,采用频率查表模糊控制法对输出电压进行控制。进行了效率和功率因数随原、副边线圈位置变化的实验,实验结果验证了该设计方案及控制方法的可行性与有效性。In view of the disadvantages of the inductive power transfer, such as low efficiency and low power factor, a novel IPT power supply in household application was designed in this paper. The main circuit of the power supply contains three parts. They are the input switching network, the resonant coupling network and the high-frequency rectifier network. The SP compensation method is adopted in the primary and secondary coil of the resonant cou- pling network. The main circuit is analyzed and the equivalent circuit of the main circuit is obtained by using the mutual inductance model method. The voltage gain is deduced to get the curves of the voltage gain changing with resonant network parameters. A prototype of a 1000W power supply is implemented. To control the output voltage, frequency look-up table fuzzy control method is adopted. The experiment of efficiency and power factor changing with the primary and secondary coil is done. The experiment results verify the correctness and effectiveness of the circuit design and control method.
