optimal control wireless energy transfer decreasing frequency
In order to solve the multiple power extreme value point problem caused by system frequency splitting during wireless energy transmission at short distances, a transmission model of the system is established. With the comprehensive consideration of the resonance frequency, load parameters and the coupling between coils, the internal factors of frequency splitting and boundary conditions are discussed. The results show that under the condition of the fixed load, the higher the natural resonance frequency, the easier the frequency splitting. As the frequency splitting occurs, the frequency of the maximum power transfer is no longer with the natural resonance frequency, which can make the system unstable and the transfer power more difficult to control. Therefore, a decreasing-frequency method is proposed to avoid the system frequency splitting. And decreasing the system resonance frequency can make the system successfully withdraw the frequency splitting area at a short-distance range. Under the fixed load condition, the transmission power of the system can be increased by 400%, and the transmission efficiency is reduced by only 14%, which greatly improves the transmission performance of the system.
