Abstract

Renewable energy-based electric vehicle (EV) charging systems have become increasingly popular in recent years, particularly in commercial and industrial environments. This study looks at a broad-spectrum bidirectional buck boost DC to DC converter employing solar photovoltaic (PV) technology. This combination is intended for usage in vehicle to grid (V2G) and grid to vehicle (G2V) modes for electric car applications. In both operating modes, the converter attains a high-voltage transfer gain ratio (VTGR) without any theoretical output voltage restrictions. It provides evidence on suitable nature for EV applications with versatility, redundancy, and practicality. The theoretical evaluation was verified by the development and testing of a 500 W experimental model. A peak efficiency of 97.8% and 97.4% in V2G and G2V modes is indicated by the data, confirming the usefulness and efficacy of this integrated strategy. These results show that the bidirectional buck boost DC to DC converter, when combined with the suggested integration of PV and EV, improves V2G-G2V operations in EV charging systems and is both practicable and feasible.

利用集成太阳能光伏技术的多功能双向降压升压型直流到直流转换器改进电动汽车充电系统

近年来，基于可再生能源的电动汽车（EV）充电系统越来越受欢迎，尤其是在商业和工业环境中。本研究探讨了一种采用太阳能光伏（PV）技术的广谱双向降压升压直流到直流转换器。这种组合适用于电动汽车应用中的车辆到电网（V2G）和电网到车辆（G2V）模式。在这两种工作模式下，转换器都能实现高电压传递增益比（VTGR），而不受任何理论输出电压的限制。它为电动汽车应用的多功能性、冗余性和实用性提供了证据。理论评估通过 500 W 实验模型的开发和测试得到了验证。数据显示，在 V2G 和 G2V 模式下，峰值效率分别为 97.8% 和 97.4%，证实了这一集成策略的实用性和有效性。这些结果表明，双向降压升压直流到直流转换器与建议的光伏和电动汽车集成相结合，可改善电动汽车充电系统中的 V2G-G2V 操作，并且切实可行。
