N2 - 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.
