当感应功率传输系统应用于电动汽车电池充电器时，将带有DC-DC转换器的二极管桥式整流电路连接到谐振电路的二次侧，以调节电池的电流和电压。在电感功率传输系统中，通常使用补偿电容器来提高输入功率因数，并配置谐振电路。提出了一种一次侧串联、二次侧并联的电感功率传输系统中一次补偿电容的设计方法(S/P拓扑)，在接收侧通过整流电路连接升压或降压变换电路。对于S/P拓扑，一次侧补偿电容的电容影响二次侧变流器中开关的占空比，因为它影响谐振电路的输入输出电压比。此外，副边转换器的占空比影响谐振电路的效率。此外，初级补偿电容影响逆变器的输出功率因数，逆变器连接到谐振电路的初级侧。因此，原边补偿电容的大小也会影响逆变器的效率和谐振电路的效率。本文研究了一种原边电容器的设计方法。结果表明，采用降压型和升压型的最佳电容是不同的。
When an inductive power transfer system is applied to a battery charger for electric vehicles, a diode bridge rectifier with a dc–dc converter, called a secondary-side converter in this paper, is connected to the secondary side of the resonant circuit in order to regulate the current and voltage of the battery. A compensation capacitor is typically used to improve the input power factor in an inductive power transfer system, and a resonant circuit is configured. This paper presents a design method for the primary compensation capacitor in an inductive power transfer system with series compensation on the primary side and parallel compensation on the secondary side (S/P topology) to connect a boost or buck converter via a rectifier circuit on the receiving side. For the S/P topology, the capacitance of the primary-side compensation capacitor influences the duty ratio of the switch used in the secondary-side converter because it affects the input-to-output voltage ratio of the resonant circuit. Further, the duty ratio of the secondary-side converter affects the resonant-circuit efficiency. In addition, the primary compensation capacitance affects the output power factor of the inverter, which is connected to the primary side of the resonant circuit. Therefore, the capacitance of the primary-side compensation capacitor also affects the inverter efficiency and resonant-circuit efficiency. In this paper, a primary-side capacitor design method is examined. The results show that the optimum capacitance using a buck converter differs from that using a boost converter.
