Abstract
A stable voltage converter is described. The stable voltage converter has an error amplifier, a plurality of subtraction circuits, a plurality of converter channels, and a plurality of current sensors. The error amplifier compares a reference voltage and an average output voltage to generate an error signal for stabilizing the output voltage of the converter. The subtraction circuits input the error signal and channel current signals generated by the current sensors, and then output modified error signals for controlling the converter channels to adequately output direct current power outputs.
