Abstract

The emergence of wireless energy transfer (WPT) technology provides another option for power transmission, which has the advantages of not being bound by cables, no electric sparks, and high mobility. Currently, wireless energy transfer systems are most widely used in SS-type compensated resonant circuits. With the coupling mechanism configuration determined, the relative position offset between the transmitting and receiving coils will affect the coupling coefficient and thus change the transmission efficiency of the system, so it is necessary to do further research on its coil position. In this paper, a SS-type topology-compensated magnetically coupled resonant wireless energy transfer (MCR-WPT) system based on an E-core magnetically coupled mechanism is analyzed and optimized in terms of the winding method of the receiving coils and the distribution position of the transmitting coils, and then a simulation comparison of the transmission efficiency is carried out according to the basic principle of the SS-type wireless energy transfer system. The simulation results show that the optimized coil position effectively improves the transmission efficiency of the system while taking into account the transmission power.
