DC-DC converters are essential to the use of elec- tric vehicles (EVs). These days, EVs need a different DC- DC converter to charge their high- and low-voltage batteries. The performance of EVs may be impacted by these variables, which have also increased output voltage ripples, switching, and device conduction losses. Furthermore, the prior multiport EV applications, converters feature a greater number of switching and energy storage components. This article suggests a multiport DC-DC converter EV charging circuit to address these problems. The suggested circuit is a single-input dual-output (SIDO) design that combines a buck converter integration with a positive output boost converter (POBCIBC). In this case, the voltage is stepped down using a buck converter and stepped up using a POBC. A basic structure made up of Cascaded Boost Super Lift Luo Converters is called the POBC. The POBCIBC design offers a number of benefits compared to the current multiport converters, such as less storage components, a compact construction, high- voltage transfer gain, proficient efficiency, decreased switching and conduction losses, and reduced output voltage ripples. By building the MATLAB/Simulpink and prototype models, the POBCIBC's performance is evaluated under various operating situations. Various output voltage levels have been created by the suggested converter according to variations in their duty cycles. The findings are displayed to demonstrate the EV application's proficient POBCIBC.
