Abstract
A power supply system includes multiple power converters, each having an input and an output. The outputs of the power converters are connected together in parallel to produce a single system output. There is a shared command bus that is coupled to each one of the power converters. A control loop in (associated with) a designated one of the power converters is operable to generate a current command signal to be output onto the shared command bus. All of the parallel connected power converters in the power supply system are configured to receive the current command signal from the shared command bus and to adjust an amount of electrical current being supplied by that power converter in response to the current command signal.
