Inductive wireless power transmission for implantable devices
2011 International Workshop on Antenna Technology (iWAT), 2011Inductive coupling is considered as one of the main stream techniques in wireless power transmission for implantable devices. In this paper, we present a generic analysis of the different topologies for wireless power transfer and arrive at boundary frequencies that separate various topologies, thereby allowing users to identify the topology that best ...

Induction in Power Transmission Lines During Geomagnetic Disturbances
Space Science Reviews, 1980The electric field associated with geomagnetic disturbances gives rise to potential differences at the Earth's surface. Thus, currents are induced in power transmission lines which are earthed at both ends through transformers. The currents vary so slowly with time that they can be considered direct currents.

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,

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. This paper

Topology and inductance analysis for wireless power transmission system
2013 25th Chinese Control and Decision Conference (CCDC), 2013Factors that affect transmission efficiency of resonance based wireless power transmission (WPT) is discussed in this paper. Two topologies of input circuit of WTP system are analyzed; Comparison of the two topologies is given on capability of output exiting current for resonance coils with angular frequency changing from 0 to 20 MHz.
