A very-high-power-transfer-density GaN-based capacitive wireless power transfer system

2017 IEEE 5th Workshop on Wide Bandgap Power Devices and Applications (WiPDA), 2017
This paper introduces a very-high-power-transfer-density GaN-based capacitive wireless power transfer (WPT) system, suitable as one module of a multi-modular WPT system for charging of electric forklifts. This capacitive WPT system achieves very high power transfer density by operating at a high switching frequency (6.78 MHz) using a GaN-based inverter,

Improvements of Transfer Efficiency in Capacitive Wireless Power Transfer Under Seawater

2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019
In this paper, the efficiency improvement in an electric coupler using an electric double layer was presented. High efficiency of a capacitive coupler can be achieved under seawater because the Q-factor improves when using an electric double layer. First, to reveal area characteristics of dielectric constant and Q-factor by measuring of seawater for an

30 W capacitive wireless power transfer system with 5.8 pF coupling capacitance

2015 IEEE Wireless Power Transfer Conference (WPTC), 2015
This paper presents a new capacitive wireless power transfer (WPT) system that achieves effective power transfer even with very low values of coupling capacitance between two metal plates separated by an air-gap. A prototype of the proposed capacitive WPT system has been built and shown to transfer 30 W across two 5-cm by 5-cm metal plates separated by
