Abstract
It is well known that when a wireless power transfer system bifurcates, the maximum power transfer capability reduces significantly. This research proposes a dynamic zero voltage switching (ZVS) controller to track the middle ZVS operation curve so as to maintain the peak power potential the system can deliver. A prototype wireless power transfer system has been developed, and it has found that the system can deliver 10 W power required to drive an implantable heart pump with a reduced input voltage, increased coil separation and improved end-to-end power efficiency.
