Abstract
The present disclosure relates wireless power transfer. In some embodiments, DC power is received through one or more inductors and switched to provide alternating current through a TX coil with a pair of power FETs coupled between opposite sides of the TX coil and ground such that current flows through one of the pair of FETs at a time. In some embodiments, the pair of FETs can be driven in adaptive resonant mode to operate at a resonance. In some embodiments, the pair of FETs are driven at a particular frequency.
