<p>In a modular power supply having a plurality of module slots capable of receiving power supply modules (PS1...PSN) therein, a system and method for controlling the power supply modules to regulate an overall output characteristic of the modular power supply, includes: (1) an overall control circuit (CONTROLLER) for sensing an overall output characteristic (VL) of the modular power supply and developing therefrom an overall error signal (Ve) representing a deviation of the overall output characteristic from a reference characteristic (VDPV) and (2) a separate module control circuit (Bj,Kj,M;) for each of the power supply modules, each separate module control circuit sensing an output characteristic (Ij) of an associated power supply module and developing therefrom and from the overall error signal a regulating signal (Vcj) for the associated power supply module, the regulating signal controlling the output characteristic of the associated power supply module to control the overall output characteristic of the modular power supply. <IMAGE></p> |
