补偿参数对串/串补偿型无线电能传输系统特性的影响分析
|
摘要
以串/串补偿型无线电能传输(S/S-WPT)系统为研究对象,为了给补偿电容参数的优化选择提供一定的指导,基于变压器T模型等效电路对S/S-WPT系统进行建模分析,得到了系统实现输出恒压时补偿电容参数需满足的约束条件。在该约束条件下,进一步分析补偿电容参数对输入阻抗、输出电压增益和系统效率的影响,并得出了输入阻抗为感性的条件、输出电压增益的调节方法以及系统效率的优化途径。实验结果验证了理论分析的正确性。
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.
