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.

Systems and methods for electrical power conversion include the provision of a full-bridge tunnel diode inverter topology which provides a balanced push-pull drive voltage and current across the entire transformer primary. Moreover, the full-bridge tunnel diode inverter may avoid operating its tunnel diodes in a high-current/high-voltage state at light loads, unlike a single-diode inverter. The disclosed principles also allow a full-bridge tunnel diode inverter topology that may avoid RF chirps in the tunnel diodes during rising or falling device ramp currents since the primary current passes through two tunnel diodes in series.
