一种用于5G基站30厘米短距离供电的6.78 MHz、90%效率谐振无线供电技术及双电压/电流调谐电感

This article proposes a dual voltage/current (V/C) inductance controller, which has good impedance tracking capability without any high-voltage stress problems. Besides, the proposed dual-mode phase-locked loop (D-PLL) technique can detect the phase difference between voltage and current of the antenna by fast tracking PLL and the accuracy-improved PLL for inductive and capacitive loads, thereby i...
