Abstract:
An apparatus for reducing ripple current comprising:an electrical network comprising input terminals A and C, and output terminals B and D, including a first inductive element and a second inductive element, each inductive element having a first terminal and a second terminal, with the second terminal of the first inductive element electrically connected with the second terminal of the second inductive element at output terminal B, with the first terminal of the first inductive element connected to input terminal A, and the first terminal of the second inductive element connected to input terminal C; and means for impressing a first source of switching potential from an external source at input terminal A and a second source of switching potential from the external source out-of-phase with the first source of switching potential at input terminal C such that a ripple current across the output terminals B and D is substantially minimal.
