Performance Investigation on Boost Converter with Non-Isolated Coupled Inductor Using PSO-DFFP Controller with Stand-Alone PV System
Abstract
The stand-alone PV system with a Partial Swarm Optimization with Distinctive Feed Forward Propagation (PSO-DFFP) controller based Boost converter is designed with coupled inductor has been simulated. The steady state / dynamic performance of the proposed system have been analyzed using MATLAB simulation. The proposed controller has been developed to decrease ripple and improve the efficiency of the system. However, the linear controllers are influenced by the system parameters of the converters; it results in reduced voltage regulation for wide variations in system parameters. Hence to over rid the limitations of analog controllers and to improve the closed-loop performance of the proposed converter, a simple PSO-DFFP controller is proposed. Consequently, its performance of the proposed controller is compared and analyzed with PID, FL (Fuzzy Logic) and PSO DFFP controller. It is observe that the invigilation of the designed system to improve the efficiency and decreases the voltage drop during the switching operation. A 200W, 100 kHz prototype model is developed and demonstrated and Experimental results are carried out to validate.
