ABSTRACT:
A circuit wherein a current sensing device is incorporated in an AC input line. An AC output is taken from the output of said current sensing device and from an other AC input line. Circuitry including two bi-directional switching regulators (positive and negative) and two energy storage capacitors adds current to or subtracts current from the instantaneous output load current. The arrangement is such that the AC output is equal to the AC input with no regulation effect. Substantially one hundred percent efficiency results when very little power factor correction is required.
