摘要

本文对一种实用的无串补偿电感无线输电链路(IWPTL)的输出特性进行了分析。结果表明，IWTPL的输出直流电压与负载有关，在一定范围内而不是恒定的。采用相域等效电路预测满负载情况下的输出直流电压，采用时域分析推导零负载情况下的输出直流电压。得到的两个值分别表示输出直流电压的下限和上限。通过380V, 1.2kW sn补偿IWPTL的仿真和实验验证了该方法的有效性。

Output Voltage Range of SN-Compensated Inductive WPT Link Operating in Load Independent Regime

The paper presents performs output characteristics analysis of a practical series-none (SN) compensated inductive wireless power transfer link (IWPTL), operating at load independent frequency. It is shown that the output DC voltage of the IWTPL is load dependent, residing in a certain range rather than being constant. Phasor-domain equivalent circuit is employed to predict the output DC voltage under full loading, time-domain analysis is used to derive the output DC voltage under conditions of zero-loading. The two values obtained represent lower and upper bound, respectively, of the output DC voltage. The proposed methodology is verified by simulations and experiments of a 380V, 1.2kW SN-compensated IWPTL.
