Abstract

The swift progression of electric vehicles (EVs) presents significant prospects for the enhanced integration of sustainable energy in the automotive industry. The installation technique and cost-effectiveness of on-board chargers (OBCs) have contributed to their increasing popularity as a feasible option for EVs. Moreover, there exists a growing demand within the automotive sector regarding bidirectional power flow solutions owing to the capacity of EVs to supply electricity to the electrical network. A crucial and integral component of the OBC is the dual active bridge (DAB) (an isolated bidirectional direct current [DC]–DC converter) satisfying the bidirectional power flow. The key aim of this work is to emphasize the essential role of the DAB within the realm of power electronic converters utilized in EVs. This paper introduces an analytical methodology for evaluating power losses and energy efficiency in a single-phase DAB. The validity of this approach is determined through a comparison between the computed energy efficiency and the empirical data obtained from a closed loop PI controlled 2.6 kW DAB model. The research article furthermore presents an analysis of leakage inductance on the efficiency and phase shift saturation in the empirical model. Subsequent comparative study evaluates the key properties of the paper, such as overall efficiency and settling time, across different loads. This inquiry offers valuable insights into the actual performance of these systems by a comparative analysis of simulation findings and real-world data obtained from hardware-based experiments.

采用单相移频调制的DAB漏感效应分析及损耗计算
电动汽车的迅速发展为汽车工业加强可持续能源的整合提供了广阔的前景。车载充电器(OBCs)的安装技术和成本效益使其越来越受欢迎,成为电动汽车的可行选择。此外,由于电动汽车向电网供电的能力,汽车行业对双向功率流解决方案的需求不断增长。OBC的一个关键和不可或缺的组成部分是双有源桥(DAB)(一个隔离的双向直流转换器),满足双向潮流。这项工作的主要目的是强调DAB在电动汽车中使用的电力电子转换器领域中的重要作用。本文介绍了一种评估单相DAB功率损耗和能效的分析方法。通过将计算的能量效率与闭环PI控制的2.6 kW DAB模型的经验数据进行比较,确定了该方法的有效性。在经验模型中进一步分析了漏感对效率和相移饱和度的影响。随后的比较研究评估了不同荷载下纸张的关键性能,如总体效率和沉降时间。通过对仿真结果和从基于硬件的实验中获得的真实世界数据的比较分析,该调查为这些系统的实际性能提供了有价值的见解。
