Fuzzy Logic Controller Based Genetic Algorithm on the Step-down Converter

DC-DC converters have wide several applications in electrical industry, they can be employed for varied DC voltage usages and stabilization or the control of DC voltage of a battery or it can be a component of a complex converter to control the intermediate or output voltages. In this paper controlled DC-DC converter using several fuzzy logic control law algorithm is studied. In order to control the response of this converter PID fuzzy logic controllers was investigated. To improve the output response of DC-DC converter, genetic algorithm was used. All the analysis and simulations to duplicate on the above converter by MATLAB software were performed. The results confirm the capability of the control method in the improvement of the above-mentioned converter functioning.
