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.

Key words： Electrical-field coupled wireless power transfer class-E amplifier tuning control
