Abstract

An interface circuit for, and method of, allowing first and second power converter systems to function in parallel and a power supply incorporating the controller or the method. In one embodiment, the interface circuit includes: (1) a set point selection circuit, coupled to first and second converter controllers of the first and second power converter systems, respectively, that selects one of the first and second power converter systems to provide a global set point voltage signal and (2) a bus, coupled to the set point selection circuit, that conveys the global set point voltage signal to the first and second power converter systems, the set point selection circuit isolating a nonselected one of the first and second converter controllers from the bus.
