Optimization of output power and transmission efficiency of magnetically coupled resonance wireless power transfer system

Abstract: Magnetically coupled resonance (MCR) wireless power transfer (WPT) system is a promising technology in electric energy transmission. But, if its system parameters are designed unreasonably, output power and transmission efficiency will be low. Therefore, optimized parameters design of MCR WPT has important research value. In the MCR WPT system with designated coil structure, the main parameters affecting output power and transmission efficiency are the distance between the coils, the resonance frequency and th… Show more

“…According to (21), once the output power of prediction is greater than the rated value, the operating mode of the system will be switched to the working mode. Similarly, the system switches to the standby mode with known phase angle γ and measured currents I in1 , I in2 .…”

“…Actually, as shown in (18), P out should be far greater than 2P P −coil + P S −coil , so the high power system could easily reach the high-efficiency working state by LCL-type DEU-WPT. And the charging area only needs to satisfy the first two conditions in (21). The controller design of charging area identification in Section IV is based on the prediction of rated output power.…”

“…By changing the coupling between coils, the efficiency increased to 71.1% and by shifting the frequency of the source over, 40% with a 2 cm distance. Yan, Rogge et al in [101] changed the structure of the coil to two coil and four coil. The RIC WPT system improved the efficiency.…”
