Local control of multiple module dc-dc converters

This paper introduces local control as applied to multiple module dc-dc converters. Local control is a form of distributed control that emphasizes each module's local information when making basic control decisions. There is no central controller or master controller. The design of simple, modular, and cooperative power converters is a primary motivating factor of this work. The challenges and opportunities of this control paradigm are placed in the context of other approaches. Simulation and experimental results for an input-series, output-parallel converter are included as an example of local control.
