Equalization method of the wireless power transfer in an electronic shelf label power supply system

Abstract

Recently, the research of the wireless power transfer (WPT) technology is brought broad interests because of its convenience at connectivity and operation safety. In this paper, we proposed a new approach to equalize the magnetic flux rather than to physically adjust gaps. But compared to our previous scheme, we added a switch to the receiving coil 1 and coil 3 respectively. This switch is used to control if make the receiving coil short or connect it to the load resistant. When the receiving coil 1 and coil 3 is electronically short, the short current will be generated. It will induce a reversed magnetic flux and therefore cancel with the magnetic flux originally induced by the transmitting yoke.
