1. A circuit for the storage and retrieval of energy, the circuit comprising:

  • a transformer having primary and secondary turns; and

    a resonant tank comprising;

    a bidirectional switch;

    a current bias gate drive for the bidirectional switch; and

    first and second terminal nodes;

    wherein the resonant tank is coupled to the transformer at the first terminal node and the second terminal node, and wherein the current bias gate drive is determined based upon a charge held in the resonant tank.
