Abstract
A modular power supply system includes DC—DC converters connected n parallel and functioning in a PWM mode. The modular power supply system controls current sharing among the DC—DC converters using a single wire current sharing control bus that drives in parallel the inputs of all the DC—DC converters. The output of each DC—DC converter is applied to a logic OR circuit. Each converter has an identical logic circuit between its output and the single wire current sharing control bus.
