Abstract
A power supply for providing two different DC voltages from a transformer having a center tapped secondary winding is disclosed. An arrangement of diodes and capacitators forming a voltage doubler is connected to the secondary winding to provide a low DC voltage from the center tap approximately equal to one half of the RMS voltage across the secondary winding, and a higher DC voltage greater than twice the RMS value of the AC voltage across the secondary winding of the transformer.
