An Enhanced DSP-Based Control Modeling and Implementation of Combinational Non-inverting High Step Up-Step Down Dc-Dc Converter

Abstract

The researchers suggest a novel hybrids control scheme for digitally implementing a positive buck-boost DC to DC topology focused on high voltage operation and sensing inductance current, as well as a current integral loop controller with a DSP-based controller. This technique is based on the principle of an integrating dynamic model, wherein the input (Vin& Iin) and heavy loads of a positive DC to DC topology are constant, while the outputs is intermittent in lower loads. As a result, the converter scheme is achieved through the blend of different dynamical features: a) Careful choice of the converter system parameters, and b) Normal of inductance current and output errors that relate to the formulation and construction of the experimental setup. Various load and input voltage fluctuation situations are modeled in Simulation and applied in the DSP controller, and all of the findings suggest that the controller is suitable. The modeling and experimental results on a positive buck-boost DCtoDC topology are acceptable.
