Abstract

The authors propose a new hybrid control system for digital implementation of a positive buck-boost DC-DC converter, based on DSP controller, high voltage regulating, and current integral loop controller for elimination of ripple inductor. This method is predicated on the theory of integrated dynamic system in which the inputs (Vin&Iin) and high loads of positive DC-DC converter is continuous and output as a discontinuous mode in lower loads. Therefore the system of the converter is accomplished by combination of two different characteristics of a dynamic modeling: a) Proper selection of the converter state variables, b) Average of inductor current and output errors that correspond to design and implementation of experimental system. Different load and input voltage variation conditions are simulated in MATLAB/SIMULINK and implemented in DSP controller and all of the results indicate the controller to verify the suitability designed controller. The simulation and experimental result on positive buck-boost DC-DC converter is found to be satisfactory.
