Abstract: The Luo converters are used for converting positive source voltage to better load voltage in the main industrial equipment. Dynamic behaviour of these converters is highly nonlinear because of their changing time and design. By changing PI parameters using optimised techniques, the efficiency of the Luo converters is improved. Genetic algorithm (GA) is developed for PI optimization in this work and also the Modified Bacterial Foraging (MBF) algorithm. The results show that MBF-PI and GA-PI controller performance is higher to the classic ZN-PI controller performance.
Keywords: DC-DC converter, positive elementary Luo converter, Genetic algorithm, Modified bacterial algorithm.
