Abstract
Wireless energy transfer system uses separable mutual induction coil to transfer energy. According to the load characteristics of rechargeable batteries, the primary and secondary sides constitute the resonant circuit with series compensation to improve power factor and transmission capability of the system. The high frequency signal source circuit of the primary side uses frequency tracking to make the system working accurately at the resonant state. The primary side current keeps constant to make system stable. The system parameters are given optimized under the loosely coupled condition considering voltage gain, frequency bifurcation phenomena and the limit of the size of the secondary side, etc.
