Wireless Power Transmission-exploring source to load inductive link performance under resonance and varying load conditions

Abstract

Recently, Wireless Power Transmission (WPT) system has been significantly crucial for the battery charging system since it is hassle free, efficient, user friendly, low cost as well as ecofriendly. Wireless power transmission (WPT) for charging up of the electronic gadgets, electric vehicles, and biomedical implants is being researched heavily these days. Researchers have been proposing the WPT technique with two categories of non-radiative and radiative. However, it had been investigated that the inductive coupling of non-radiative technique is much more efficient than the radiative technique. As wireless power transmission in configurations at many-to-one as well as one-to-many systems is concerned the selective resonant frequency has got a role to play. This dissertation explores the one-to-one and one-to-two power transmission inductive link scenarios. The technique of analysis of both of these links is based on studying the effect of the magnitude of the reflective impedance to estimate the power transfer efficiency. To evaluate the performance of both of, the scenarios the MATLAB and Pspice software analysis and simulation tools are used. The result suggests that the output efficiency has been improved for 1-to-many and many-to-one application, scenarios.
