A comprehensive evaluation of using Bio Inspired Optimization Algorithms to enhance the dynamic performance of unity power factor AC-DC Boost Converter is presented in this paper. To achieve constant output voltage and unity power factor at supply mains, Sliding Mode controller in cascade with the PID voltage loop controller is normally used to control these converters and it is highly evident that the performance of these converters is highly influenced by PID controller gains. This paper reviews the feasibility of using Bio inspired Optimization Algorithms to find an optimal PID gain that enhances the dynamic and static performance of the converter. The objective function formed for the optimization problem is framed from time domain performance parameters. From simulation results, it is deduced that the Bio Inspired optimization based PID gain results in an enhanced converter performance compared to its traditional counterpart.
