Abstract
A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate in near real time for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs.
