Optimization of PI Controller using PSO for Power Electronic Converter

DC-DC converters are widely used in application such as computer peripheral power supplies, car auxiliary power supplies and medical equipment’s. Positive output elementary Luo converter performs the conversion from positive source voltage to positive load voltage. Due to the time-varying and switching nature of the power electronic converters, their dynamic behavior is highly non-linear. Conventional controllers are incapable of providing good dynamic performance and hence optimized techniques have been developed to tune the PI parameter. In this paper, Particle Swarm Optimization (PSO) is developed for PI optimization.
