Preliminary Design by Modeling S-CPT System With Inductance Consideration

Capacitive power transfer (CPT) offers power transfer between transmitter and receiver by using plates. This work purposes to model, analyze and design a CPT system for shielded capacitive power transfer (S-CPT) by inductance consideration. The inductance in S-CPT contributes to the power loss and the overall system’s size and weight. Total impedance with analytical approach is utilized to analyze the S-CPT system by using Matlab software. The proposed S-CPT topology is designed with operating frequency of 6.78 MHz for 5W. Both simulation and experimental are demonstrated for the S-CPT system.
