ABSTRACT:
A circuit having voltage regulated DC-output is provided, which may have balanced DC voltages with respect to zero, and which has only a single voltage sensing and power regulating means. The power regulator is on the input of a transformer having at least a bifilar wound secondary and a center tap. One or more pairs of balanced taps, one of each pair on either side of the center tap, are provided; and to each tap there is connected a pair of oppositely facing diodes, connected as to their polarity to provide positive or negative DC voltage with respect to zero; with similarily connected diodes from each pair of diodes at each tap being tied together at their output, facing the output of the circuit. In series with the output terminals of the circuit there are closely coupled, bifilar wound chokes, wound on a single core with isolated windings, and polarity connected to the respective outputs.
