Abstract

This paper presents a novel power distribution system for supplying multiple individually regulated outputs from a central power supply acting as a controlled current source that contains all the magnetic components. The individual output voltages are filtered by means of capacitors. The current source is realized with a buck converter. The outputs are connected to the current source on a time-shared basis and regulated individually by constant frequency PWM. The buck converter is controlled using average current control. Simulation results and experimental results from a laboratory prototype are presented.
