Inductive Resonant Coils for Biomedical Wireless Power Transmission
2020 IEEE Wireless Power Transfer Conference (WPTC), 2020This study analyzes wireless transmission efficiency in magnetic resonance topology. In wireless power transmission systems, the overall efficiency is limited by the power consumption of coils. To improve the efficiency of wireless power transmission systems, this study proposes a suitable design for implantable devices by studying the shapes of coils,

Inductive power transmission for untethered micro-robots
31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005A new concept for inductive power transmission is proposed to transmit constant power over a large area of interest. This concept includes a specially designed winding group at the power transmitting side, which is similar to the windings in a linear motor. The winding group generates a traveling magnetic field over the complete working area.

Design of inductive power transmission systems considering tolerances and power loss
2009 35th Annual Conference of IEEE Industrial Electronics, 2009With contactless inductive power transmission it is possible to transfer electrical energy in industrial, business or consumer electronics over an air gap and therefore avoiding sliding contacts, trailing cables or slip rings. The paper presents a concept for a computer-aided modelling and design of inductive power transmission systems.

Teaching Calculation of Inductance of Power Transmission Lines
International Journal of Electrical Engineering & Education, 2011The conventional derivation of the expression for inductance of power transmission lines given in books is more a recipe than a derivation starting from a law of physics. The serious shortcomings of the traditional approach are that the definition of flux linkage lacks strong connection to Faraday's law, and unnecessary assumptions are made.
