Abstract

This paper proposes a method to reduce an electric field emission of shielded capacitive power transfer (S-CPT) at an operating frequency of 6.78 MHz by utilizing different types of dielectric materials. FEA analysis was conducted to analyze which dielectric materials had the most significant effect on reducing electric field emissions. Specifically, air, mineral oil, paper, FR4, halowax, rubber and glass are the materials used in this proposed project. Those dielectrics were placed in between the coupler and the shielded plate. It also summarizes theoretical research in capacitive coupler structure. In addition, it illustrates the essential operating concept of the capacitive power transfer (CPT) system, including the CPT technology in several fields, such as medical devices, communication consumers, and transportation. The S-CPT system's impedance matching parameters were determined through analysis using the LTspice software. The experimental findings are demonstrated to show the effectiveness of the proposed solution.
