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), 2017This 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,

A dynamic capacitive power transfer system with reduced power pulsation
2016 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW), 2016This paper proposes a dynamic capacitive power transfer (CPT) system which utilizes electric fields to transfer power to a moving receiver. The transmitter is a long track, consisting of a pair of aluminum plates. One important property of this transmitter structure is reducing the power pulsations at the receiver.

User-Defined Power Distribution for Capacitive Wireless Power Transfer With Multiple Receivers
2024 IEEE Wireless Power Technology Conference and Expo (WPTCE)Abstract: Capacitive power transfer allows for wireless charging of multiple devices at once. In a typical system, the amount of power delivered to the different devices is determined by their position and distance to the transmitter. However, it can be beneficial to prioritize the charging of the devices.
