Abstract
These days wireless power transfer is the widely used technology to transmit power and information simultaneously. In this paper, the magnetic induction principle is used to transfer power and information simultaneously through a single winding arrangement. It is shown that a 7W LED lamp can be illuminated between a distance of about 5mm. Magnetic induction principle can be applied to a short-range power and information transfer only. This paper discusses the underwater LED light luminaire transmitter and receiver design components, along with it shows the mode switching of LED. The power transfer efficiency is about 65% when the transmitter and receiver are placed in-line and power efficiency decreases with the displacement of the lamp to either side.
