【摘要】：系統(tǒng)的頻率直接影響磁耦合諧振無線電能傳輸電能質(zhì)量和傳輸效率。從新的角度對其進(jìn)行研究,通過計(jì)算由高頻逆變電路產(chǎn)生的各次諧波分別對傳輸系統(tǒng)原副邊電流的響應(yīng),來分析頻率對磁耦合諧振無線傳輸系統(tǒng)電能質(zhì)量和傳輸效率的影響。最后,設(shè)計(jì)了硬件電路并進(jìn)行了相關(guān)研究,實(shí)驗(yàn)結(jié)果與理論和仿真分析取得了較好的一致性,證明了該方法的有效性和準(zhǔn)確性。結(jié)果表明系統(tǒng)的頻率越接近諧振頻率,原副邊電流畸變率越小并且傳輸效率比較高。
[Abstract]:The frequency of the system directly affects the power quality and transmission efficiency of the magnetically coupled resonant radio. From a new point of view, the effects of frequency on the power quality and transmission efficiency of the magnetically coupled resonant wireless transmission system are analyzed by calculating the response of each harmonic generated by the high-frequency inverter circuit to the primary and secondary current of the transmission system respectively. Finally, the hardware circuit is designed and the related research is carried out. The experimental results are in good agreement with the theory and simulation analysis, and the validity and accuracy of the method are proved. The results show that the higher the frequency of the system is, the smaller the distortion rate of the primary and secondary current is and the higher the transmission efficiency is.
