Abstract: In this paper, the mathematical modelling, designing, and testing of non-isolated and isolated converters like Cuk, SEPIC, and forward converters are described. All the tests were performed to obtain the best converter which plays a major part in the charging of the EV application. This can be done by using a PI controller-based closed-loop control technique that helps Cuk, SEPIC, and forward converters make it more robust. Since finding the value of K_p and K_i is a very difficult task in nonlinear systems like converters. Various optimisation techniques (OTs) like differential evolution (DE), particle swarm optimisation (PSO), artificial bee colony (ABC), and sparrow search optimisation (SSO) are utilised in this paper to find the optimum value of PI control gain. It is said that analysing the performance of all converters and OTs shows their best performance in a specific working condition.

Keywords: artificial bee colony; ABC; DC-DC converter; differential evolution; DE; mathematical modelling; particle swarm optimisation; PSO; sparrow search optimisation; SSO.
