Interleaved Capacitive Coupler for Wireless Power Transfer
IEEE Transactions on Power Electronics, 2021Capacitive 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.

A Constant Output Capacitive Wireless Power Transfer System Based on Parity-Time Symmetric
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2023In existing capacitive wireless power transfer (CPT) systems, the coupling capacitance of the traditional couplers is usually small, which will lead to a significant decrease in the power transfer capability when the transfer distance increases. Thus, it
