Abstract：For the primary-side high frequency power converting module of an electric-field coupled wireless power transfer system, a new topology combining class-E amplifier with static capacitor-inductor-capacitor(CLC) tuning circuit is proposed and calculation equations of the main parameters affecting the transmission power and efficiency are derived. Concerning about the frequency-shifting problem caused by parameter variation, a dynamic tuning control method with capacitance matrixes is proposed, with which the system resonance frequency can be stabilized and the soft-switching condition can be guaranteed consequently. Therefore, the system performance can be optimized. Simulation and experimental results verify the validity of the proposed topology and tuning control method.
