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. The bidirectional power converter circuit is used in a proximity wireless power transmitter and a proximity wireless power receiver, such that the transmitter and receiver may be misaligned in any direction while providing power from the transmitter to the receiver without damaging any circuitry of either the bidirectional power converter transmitter or the bidirectional power converter receiver.
