This study presents an improved autonomous current-fed push??pull resonant inverter with integrated driving power from the input DC source and zero voltage switching (ZVS) signals from the resonant tank. Unlike the conventional currentfed inverters, the new inverter can increase the system operating frequency up to MHz while maintaining ZVS operation. Moreover, the primary resonant capacitance can...
High power inductively powered implantable devices (5–15 W) such as an artificial heart demand continuous power over widely varying coupling and loading conditions. An energy injection converter is suitable for driving the power transfer coil of an inductive power transfer system for this application because of its ability to control power flow over a large coupling range without any additional power...
