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

High Power Wireless Power Transfer with Inductive Coupling
ECS Transactions, 2020This paper describes the design of a high power wireless power transfer with a coupled series resonant circuit. Coils distance is 600 mm and a nominal power is 20 kW. The transfer is provided by the inductive coupling of the resonant circuit with 800 mm diameter coils.

Inductive Power Transfer for 100W battery charging
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013Today, Inductive Power Transfer (IPT) is widely investigated to provide wireless battery charge. Potential applications range from a few Watts of handheld devices to kWatts of automotive applications. Despite of comfort and safety options, wireless charging features relatively poor power conversion efficiency.

A high power coaxial inductive power transfer pickup
2008 IEEE Power Electronics Specialists Conference, 2008A new pickup termed the "coaxial pickup" is presented in this paper, specifically designed to meet increased power demands by industry. The pick-up is designed for inductive power transfer applications where high power is delivered to a load, which operates on an essentially straight monorail section (such as a lift).

Magnetostimulation by inductive power transfer systems
2013 IEEE Radio and Wireless Symposium, 2013Inductive wireless power transfer (IPT) necessarily involves intense time-varying magnetic fields. As predicted by Faraday's law, the time-varying magnetic flux due to the primary-side coupler of an IPT system induces electric field and hence current in all conductive materials which enter its field, intentionally or inadvertently. Thus, we examine the

A ring inductive power transfer system
2010 IEEE International Conference on Industrial Technology, 2010Inductive Power Transfer (IPT) is an efficient and well established technique for contactless or wireless power transfer, and has numerous applications over a wide power range. Although the demand for high power IPT systems is growing, the implementation of such IPT systems is severely hampered by the limitations of voltage and current ratings of ...

A Fundamental-Harmonic Hybrid Power Transfer Strategy for Bidirectional Inductive Power Transfer
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021For bidirectional inductive power transfer (BIPT) system, transmission efficiency optimization and widen zero voltage switching (ZVS) is important. In the BIPT system, to optimize the above issues, the dual-phase-shift (DPS) and triple- phase-shift (TPS) with the fundamental component are adopted.

Interphase Mutual Inductance in Polyphase Inductive Power Transfer Systems
IEEE Transactions on Industrial Electronics, 2009Roadway powered electric vehicles with minimal or no onboard energy storage have been proposed for many years, but the concept has only recently become feasible via three-phase inductive power transfer (IPT) systems. A wide zone can be created over which power transfer is relatively constant.
