Light electric vehicles (LEV) necessitate power electronic converters that have a high-power density and a high efficiency in order to accommodate the limited space available. The input voltage of a four-switch buck-boost converter can be increased or decreased across a wide range, allowing for energy to be transferred in either direction. This type of converter topology is particularly efficient. In this study, an algorithm is presented that proposes two different designs for a four-switch buck-boost converter within both efficiency and cost constraints. Two 96-12-5 V, 500 W converter that is powered by a 48 V battery have been developed for the purpose of determining whether or not the proposed algorithm is effective. The proposed algorithm chose the switches, inductance, and capacitance based on a previously created database.
