There is a conflict between the energy transfer efficiency and maximum transferred power in conventional inductive power transfer (IPT) systems, and the energy transfer efficiency is only 50% when maximum power is transferred. To solve this problem, a new topology which is operated at switched-mode is proposed in this paper. The high frequency current of the topology is generated by the free oscillation...
Transcutaneous energy transfer (TET) is capable of supplying power across the skin to implantable devices and avoids the risk of infection associated with wires passing through the skin. These systems rely on a high frequency magnetic field to overcome the relatively low coupling between a coil located outside the body, and a coil implanted within the body. This paper introduces a new optimisation...
Electromagnetic wireless resonant energy links (WRELs) can be realized by using resonant coils coupled via their magnetic fields. By means of a simple equivalent network we investigate the efficiency of WRELs. It is demonstrated that, in order to improve the efficiency, a matching network at the input and output section should be used. In our arrangement the matching network is made by placing the...
