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.
