Abstract
A DC power supply capable of providing a number of output voltages, including a balanced positive and negative voltage supply for integrated circuit applications, includes a transformer having primary and secondary windings. A diode bridge rectifier circuit is connected across the secondary winding end terminals for providing a DC output voltage of one polarity with respect to ground. Another DC output voltage of opposite polarity is developed by AC coupling a voltage multiplier circuit between one of the secondary winding terminals and ground. DC regulator circuits are included for regulation of the DC output voltages under load conditions.
