Frequency Bifurcation Conditions for Capacitive Wireless Power Transfer with Multiple Receivers [PDF]
2022 Wireless Power Week (WPW), 2022 Abstract: Capacitive wireless power transfer applies the electric field to transport energy from a transmitter to a receiver. However, if the distance between transmitter and receivers varies, the efficiency or power transfer is reduced for a system with a fixed load.

User-Defined Power Distribution for Capacitive Wireless Power Transfer With Multiple Receivers [PDF]
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.
