Abstract: The DC-DC switched-mode boost converter is well-known for its extensive applications ranging from few watts to several megawatts in different engineering fields. In this paper, a closed-loop boost converter has been designed and implemented by using classical and particle swarm optimisation (PSO) based optimised type-II/type-III controllers. The closed-loop control for boost converter is difficult due to the presence of a right-half-plane zero, and it is problematic for the conventional PID controller to exhibit good closed-loop performance with line, load changes and parametric uncertainty. The comparative studies between the closed-loop performances of the proposed boost converter with classical and optimised type-II/type-III controllers have been produced. Simulations and experimental results are provided to demonstrate the effectiveness of proposed optimised controllers for the boost converter. It is found that the PSO optimised type-III controller exhibits better stability and closed-loop performance than the other reported controllers in this paper.
