Abstract

The increasing popularity of Electric Vehicles (EVs) can be attributed to recent advancements in highly efficient power conversion technology, as well as a desire to reduce reliance on fossil fuels. As a result, bidirectional DC-DC converters have gained significant interest and importance in the field of electric vehicle applications. This paper introduces an enhanced DC-DC converter, the Bidirectional Dual-Input Single-Output (BDISO) converter for the Electrical Vehicle application, which combines multiple energy sources for efficient power delivery to a load. The converter offers versatile operational modes and employs a Passivity-Based Control (PBC) strategy for stable closed-loop control. A mathematical model is developed and analyzed to understand its behavior. In addition, rigorous evaluations of reliability and efficiency demonstrate robust performance and high operational efficiency across various conditions in comparison with exciting systems. Finally, the proposed converter with its controller is validated through simulation and experimental results.

基于无源控制策略的双向双输入单输出 DC-DC 转换器

电动汽车（EV）的日益普及可归因于高效电源转换技术的最新进展，以及减少对化石燃料依赖的愿望。因此，双向直流-直流转换器在电动汽车应用领域获得了极大的关注和重视。本文介绍了一种用于电动汽车应用的增强型直流-直流转换器--双向双输入单输出（BDISO）转换器，该转换器结合了多种能源，可高效地向负载输送电力。该转换器提供多种运行模式，并采用基于无源控制（PBC）策略进行稳定的闭环控制。为了解其行为，开发并分析了一个数学模型。此外，对可靠性和效率的严格评估表明，与令人兴奋的系统相比，该系统在各种条件下都具有稳健的性能和较高的运行效率。最后，通过仿真和实验结果验证了所提出的转换器及其控制器。
