A Particle Swarm Optimization (PSO)-based Tuning Method for LC/CL-compensated Capacitive Power Transfer Systems

This paper develops a capacitive power transfer (CPT) system for rotating electromechanical equipment. The compensation inductances are significantly reduced by employing the primary inductor-capacitor secondary capacitor-inductor (LC/CL) compensation network. To obtain steady output voltages even if the power transfer distance is varied, a particle swarm optimization (PSO)-based tuning method is proposed. The superiorities of the proposed tuning method is verified by simulation.
