Role of Dielectrics in the Capacitive Wireless Power Transfer System

2020 IEEE International Conference on Industrial Technology (ICIT), 2020
Wireless power transfer through capacitive coupling interface is being investigated widely as a dual of inductive coupling interface for low to medium air-gap (~1 mm – 100 mm) applications. The value of coupling capacitance is generally dependent on the dielectric material used, area of the plates in the interface and distance between the plates.

Interleaved Capacitive Coupler for Wireless Power Transfer

IEEE Transactions on Power Electronics, 2021
Capacitive power transfer is becoming an attractive alternate for wireless chargers. A coupler with large self- and mutual capacitance is desirable from the power and efficiency perspective. However, state-of-the-art couplers suffer from the tradeoff design issue between these two types of capacitance.
