ABSTRACT:
A multiple-output DC-DC converter has an electronically controllable reactor (64,66) connected in series with each output circuit. In response to variations in voltage of the output circuits (80,82), control signals are fed back to vary the permeance of the electronically controllable reactor (64,66) in each output circuit. The voltage in any output circuit is thereby made independent of input voltage variations and load fluctuations in any other output circuit.
