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 (48V) 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.

电动汽车单输入多输出DC-DC Buck变换器的设计与实现

运输部门使用了世界石油产品的很大一部分，从而增加了温室气体 (GHG) 的排放。电动汽车 (EV) 具有解决温室气体排放的潜力。对 EV 的要求带来了许多不同的问题，例如使用 DC-DC 转换器将电压电平从电池转换到 EV 的其他部分。介绍了一种具有单输入和双输出的非隔离式 DC-DC 降压转换器的设计和实现，该转换器也称为单输入多输出 (SIMO) 转换器。该转换器专为电动汽车设计。电池（48电动汽车的 V) 用作 SIMO 的输入。本文介绍了变流器的小信号分析和有效控制策略。对系统进行了仿真，并与实验结果进行了比较。
