Abstract
A multiple output DC power supply having a single closed loop control system for two or more power amplifiers which provide matched DC outputs. The control system is responsive to the sum of the DC signals output from the power supply to derive an average error signal. A switching logic circuit compares signals representing the unregulated AC power driving the power amplifiers to a reference signal in order to generate a set of control signals for each of the amplifiers, the average error signal biasing the reference signal so as to vary the time of occurrence of the control signals and regulate the DC outputs.
