Abstract
A balanced, constant current power supply having two rectifying bridges coupled in parallel is energized by an AC source for generating a plurality of DC output voltages. The parallel arrangement of diode rectifying bridges permits the use of low cost, polar electrolytic capacitors in the power supply and results in a balanced circuit capable of generating a plurality of parallel DC outputs. The AC-driven, DC power supply of the present invention operates without a transformer and, in combination with a plurality of shunt regulators, is capable of providing a plurality of well-regulated DC output voltages.
