The Duality of Inductive Power Transfer and Capacitive Power Transfer
2020 8th International Conference on Power Electronics Systems and Applications (PESA), 2020Both inductive and capacitive wireless power transfer can be used for the charging of electric vehicles theoretically. In this paper, the mutual-capacitance coupling model of capacitive power transfer is proposed by analogy with the mutual-inductance coupling model of inductive power transfer. In single input single output (SISO), multiple input single

Analysis of transfer power of capacitive power transfer system
2013 IEEE 10th International Conference on Power Electronics and Drive Systems (PEDS), 2013There are three method for wireless power transfer from the viewpoint of transfer field. The first is inductive power transfer (IPT) using magnetic field which is currently the most popular way to realize wireless power transfer. The second is wireless power transfer using radio wave.

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.

Effective Capacitive Power Transfer
IEEE Transactions on Power Electronics, 2012Capacitive power transfer (CPT) systems have up to date been used for very low power delivery due to a number of limitations. A fundamental treatment of the problem is carried out and a CPT system is presented that achieves many times higher power throughput into low-impedance loads than traditional systems with the same interface capacitance and ...

Design of auto-tuning capacitive power transfer system for wireless power transfer
International Journal of Electronics, 2015ABSTRACTThis paper presents the design of capacitive wireless power transfer systems based on a Class-E inverter approach. The main reason for adopting the Class-E inverter approach is because of its high efficiency, theoretically 100%. However, the operation of a Class-E inverter is highly sensitive to its circuit’s parameters. In a typical capacitive

Capacitive power transfer with impedance matching network
2016 IEEE 12th International Colloquium on Signal Processing & Its Applications (CSPA), 2016This paper presents the development of a new wireless power transfer technique using capacitive coupling. Capacitive power transfer (CPT) system has been introduced as an attractive alternative to the traditional inductive coupling method. This is due to the CPT benefits of simple topology, fewer components, better EMI performance and robustness to ...
