摘要:
      为对串/串(S/S)补偿型无线电能传输(WPT)系统的输出特性、输入阻抗和系统效率进行分析,首先基于变压器T型等效电路,对系统进行建模,然后以补偿电容值为变量,分别分析其在电压源激励和电流源激励下的情况,经过分析主要得出以下结论:输出特性方面,电容补偿自感时,激励为电压源输出为电流源,激励为电流源输出为电压源,而补偿漏感时,激励为电压源输出为电压源,激励为电流源输出不具有电压源或电流源特性;输入阻抗方面,电容补偿自感时为纯阻性,补偿漏感时偏感性;系统效率方面,电容补偿自感时系统效率最优,任何补偿情况下系统均存在一个相应的效率最优负载。最后,通过实验验证了上述结论的正确性。
Abstract:
      In order to analyse the output characteristics, input impedance and system efficiency of series/series(S/S)compensated type wireless power transfer(WPT)system a model is set up based on transformer T-equivalent circuit. Then set the compensating capacitor as a variable to analyze the characteristics of system under the excitation of voltage source and current source, respectively. The conclusions are obtained from analysis. With respect to output, it is current source when input is voltage source and output is voltage source when input is current source under the condition the capacitor compensates for self-induction. But output is voltage source when input is voltage source and output is not voltage or current source when input is current source under the condition the capacitor compensates for leakage inductance. Input impedance is purely resistive when the capacitor compensates for self-induction. And input impedance is partially inductive when the capacitor compensates for leakage inductance. System efficiency is optimal when the capacitor compensates for self-induction. There is a corresponding load able to make the efficiency optimal whatever the compensation. Finally, the conclusions are verified by experiments. This work is supported by National Natural Science Foundation of China(No. 51307173).
