Abstract
The transportation sector uses a big portion of the world’s petroleum products thus increasing the greenhouse gas (GHG) emissions. Electric vehicles (EVs) have the potential to solve GHG emissions. The requirements for EVs have brought many different problems such as the conversion of voltage level from the battery to other parts of the EV using DC–DC converters. The design and implementation of a nonisolated DC–DC buck converter with single input and dual output are presented, which is also called the single-input multiple-output (SIMO) converter. The converter is designed especially for electric cars. The battery (48[Formula: see text]V) of the electric vehicle is used as an input to the SIMO. Small-signal analysis and effective control strategy for the converter are presented in this paper. The simulation of the system is performed and compared with the experimental results.
