Abstract
This paper proposes a current-fed capacitive power transfer (CPT) system with a basic parallel-series (PS) compensation for step-down constant-voltage (CV) output. There are three main contributions. First, a resonant current source inverter (CSI) is designed at the input side to excite a parallel LC resonant tank, which generates a sinusoidal voltage and achieves zero-voltage-switching (ZVS) at both turn-on and off transients. Second, a parallel-series CPT compensation is proposed and modeled by the g-parameters of a two-port network, realizing voltage step-down and zero-phase-angle (ZPA). Third, considering parasitic resistances, the output voltage attenuation and system efficiency are studied at different loads, couplings, and quality factors. A 150W PS-compensated prototype is implemented with 150mm300mm metal plates. Experiments validate the voltage step-down property with a voltage gain of 0.4 and a peak dc-dc efficiency of 87.3%.
