In this project, a novel optimization model based on the Particle Swarm Optimization (PSO) algorithm for the closed loop controller design of a converter is designed to obtain the static and dynamic characteristics at all operating points. To test the methodology, the smallsignal model of a boost type DC-DC converter is used to evaluate the objective function to yield a robust closed-loop controller structure that is subjected to internal and external disturbances. Design equations are derived and the system is modeled in MATLAB. The project objective is derived from the experts work on pos& researches. Main objective of project is to delivering max output using PSO algorithm & to obtain optimum solution for PWM injection. In this project the max optimal efficiency is obtain from the proposal and also output simulated and monitored.
