Generators are buck parallel-converter controlled power sources using droop load regulation characteristic for power sharing. Zone loads are represented by three groups of parallel-connected buck converters. Each group has its own priority depending on importance of the load. Research Projects Synergetic Control Strategies for Parallel-Connected Buck Converters Research objectives: - Derive synergetic control strategies for parallel-connected converters using different method of current sharing - Explore properties of closed loop systems - Explore current sharing performance - Compare synergetic control strategies with most competitive ones. The main tool in this research is a synergetic control theory. Synergetic control theory is based on ideas of self-organization and allows designer to derive analytical control laws for nonlinear, multiconnected, high dimensional systems. As a result, a number of synergetic control based VTB converter modules will be designed. It is a hope of the researcher that these modules will facilitate design of complex DC autonomous power systems.
