Abstract

Environmental considerations are driving up the popularity of electric vehicles (EVs) in cars. Since the rechargeable battery powers electric vehicles, having a dependable, economical, and effective battery charger is crucial to delivering the reliable output needed for the particular EV’s battery. The proposed work presents a modified PI controller in a DC-DC converter that helps minimise the charging time by achieving the high current density and necessary output voltage with barely overshoot. The recommended method not only decreases the active switches’ power loss but also minimises the junction temperature, thus increases the converter’s lifespan. In both ideal and non-ideal circumstances, the suggested converter is analysed. To develop an effective and economical dc as well as ac side inductor, the outcome of total power dissipation and elevated temperatures has been in examined. According to the findings, the suggested converter can keep the high-density load current running at a power factor of about 90.1% and a THD of about 0.45%. Also, dc-dc converter’s dependability is examined. To ensure its practicality for EV battery charging applications, a hardware prototype has also been put into practice.
