摘要：
Series/series compensation wireless power transfer (S/S-WPT) system is chosen as the study object. In order to provide some guidance for optimal selection of compensation capacitance, the S/S-WPT system is modeled and analyzed based on the equivalent circuit of transformer T-model. The constraint condition of compensation capacitance for constant output voltage is obtained from the theoretical analysis. With the constraint condition, the effects of compensation capacitance on the input impedance, output voltage gain and system efficiency are analyzed in detail. This paper obtains the condition to make input impedance inductive, the method to adjust output voltage gain and the way to optimize system efficiency. Finally, the theoretical analysis is verified by experiments. © 2019 Automation of Electric Power Systems Press.
