The present text provides information regarding introductory concept of wireless power transfer by studying some of the existing technologies and evaluate its quality factor as well as deals with certain methods of improving the efficiency of wireless power transfer. In addition to this, calculation and analysis has also been done for its figure of merit, transfer loss, quality factor and efficiency.
Recently the information from industry shows that inductive power transfer electric vehicle chargers that use tight coupling between the inductive coupler coils were achieved. This paper includes a theoretical and experimental study on the possibilities that tight coupling offers versus loose coupling - widely used so far - in what concerns the ratio between the output transmitted power and the efficiency...
Wireless Power Transmission ( WPT) based on strongly coupled resonances can be achieved medium-range distance. In this paper, a system of wireless power transmission based on strong-coupling resonances is presented. We analyse the strongly coupled model of the system and investigate the efficiency of the resonator's receiving coils with characteristics of the distance and the extreme problems experimentally...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
