A novel integrated converter for electric vehicles (EVs) is proposed in this article. For battery-charging operation, the proposed converter system enables a complementary deployment of the utility grid and a solar photovoltaic (PV) system. Since both sources (acting one at a time) utilize the same converter, the developed charging system, therefore, has a smaller number of components. In addition, an inductor voltage detection (IVD) technique has been incorporated to correct the power factor (PF) in continuous conduction mode (CCM), which eliminates the need for a current sensor for PF correction (PFC). The proposed system operates for all the modes required for an EV, e.g., charging, propulsion (PRN), and regenerative braking (RBG). In charging mode (with either grid or solar PV), the proposed system operates as an isolated secondary ended primary inductance converter (SEPIC) converter. In PRN and RBG modes, it operates as a boost converter and a buck converter, respectively. Details of all these modes are described in the article, along with the design of the components. In addition, results of simulation and experimental studies are presented for a 1-kW setup based on the proposed configuration. A comparison with other topologies shows the technoeconomic competence of the proposed system.

一种减少组件的集成转换器，用于利用太阳能和电网电源的电动汽车

本文提出了一种用于电动汽车 (EV) 的新型集成转换器。对于电池充电操作，所提出的转换器系统可以实现公用电网和太阳能光伏 (PV) 系统的互补部署。由于两个电源（一次作用一个）使用相同的转换器，因此开发的充电系统具有较少数量的组件。此外，还采用了电感电压检测 (IVD) 技术来校正连续导通模式 (CCM) 下的功率因数 (PF)，从而无需使用电流传感器进行 PF 校正 (PFC)。所提出的系统适用于 EV 所需的所有模式，例如充电、推进 (PRN) 和再生制动 (RBG)。在充电模式下（使用电网或太阳能光伏），建议的系统作为隔离式次级端初级电感转换器 (SEPIC) 转换器运行。在 PRN 和 RBG 模式下，它分别作为升压转换器和降压转换器运行。文章中描述了所有这些模式的详细信息以及组件的设计。此外，还介绍了基于建议配置的 1 kW 设置的模拟和实验研究结果。与其他拓扑结构的比较显示了所提议系统的技术经济能力。模拟和实验研究的结果是针对基于建议配置的 1 kW 设置提出的。与其他拓扑结构的比较显示了所提议系统的技术经济能力。模拟和实验研究的结果是针对基于建议配置的 1 kW 设置提出的。与其他拓扑结构的比较显示了所提议系统的技术经济能力。
