Abstract

The design and development of a 550 W non-isolated single-phase two-stage level-1 bidirectional on-board battery charger (OBC) for electric vehicles (EVs) have been discussed in this article, which is also capable of supplying the utility grid's reactive power needs. There are two stages in this topology. The first stage consists of a full bridge bidirectional AC to DC converter, and the second stage consists of a half-bridge bidirectional DC to DC converter with enhanced vehicle-to-vehicle (V2V) capabilities for emergency roadside charging assistance scenarios. In an emergency, if there is not a charging station nearby and the battery is dead, EVs can use this feature to charge from other EVs. It can also work like a regular vehicle-to-grid (V2G) or grid-to-vehicle (G2V) system. The suggested charging topology has a maximum efficiency of 99.09%, a power factor of 0.99, and a total harmonic distortion (THD) of 6.31%. MATLAB/Simulink is used to develop and simulate the suggested EV charger, and simulation results are compared with the other on-board chargers in the literature.

用于电动汽车的高性能单相双向新型车载充电器

本文讨论了用于电动汽车（EV）的 550 W 非隔离单相两级一级双向车载电池充电器（OBC）的设计和开发，该充电器还能满足公用电网的无功功率需求。该拓扑结构分为两个阶段。第一阶段由全桥双向交流到直流转换器组成，第二阶段由半桥双向直流到直流转换器组成，具有增强的车对车（V2V）功能，适用于紧急路边充电援助场景。在紧急情况下，如果附近没有充电站，而电池又没电了，电动汽车可以利用这一功能从其他电动汽车上充电。它也可以像普通的车对网（V2G）或网对车（G2V）系统一样工作。建议的充电拓扑结构的最高效率为 99.09%，功率因数为 0.99，总谐波失真 (THD) 为 6.31%。我们使用 MATLAB/Simulink 对建议的电动汽车充电器进行了开发和仿真，并将仿真结果与文献中的其他车载充电器进行了比较。
