Design of capacitive power transfer system with nanofarad-scale coupler and optimized compensation network

Year: 2025

Type: article

Abstract: Capacitive power transfer (CPT) do not produce eddy current effects and are concentrated between plates. To increase the capacitance of CPT coupler and satisfy the charging demands of loads, a novel coupler and its associated compensation network are proposed. The coupler elevate the equivalent capacitance to nanofarad-scale. The compensation network designed in this paper can achieve input zero phase angle (ZPA) and load-independent constant-voltage (CV) output. Experimental results demonstrate that the designed coupler's equivalent capacitance is several times greater than that of traditional structures. The compensation network successfully meets the requirements for input ZPA, CV output, and anti-misalignment performance.
