摘要

提出了一种单电池双逆变系统的电动汽车控制方法。传统的双逆变系统由一个开放式绕组电机和两个逆变器组成，每个逆变器由一个独立的电池供电。在电池发生故障的情况下，通过将故障侧平滑电容的电压控制为电池电压的一半，可以作为多级逆变器运行，从而有望提高系统效率。然而，在电动汽车的整个工作区域内，很难将电容器电压保持在电池电压的一半。因此，开发了一种根据工况在单逆变器运行和双逆变器运行之间切换，并响应运行切换过程中电容电压变化的控制方法。通过硬件环内仿真和实验车验证了所提出的控制方案。

Control Method of Dual Inverter System for EV with One Battery

A control method for electric vehicle (EV) of a dual inverter system with one battery is proposed. The conventional dual inverter system consists of an open-end winding motor and two inverters, and each inverter is powered by an independent battery. In the case of a battery failure, it can be operated as a multi-level inverter by controlling the voltage of the smoothing capacitor on the failure side to half of the battery voltage, and improvement in system efficiency can be expected. However, it is difficult to maintain the capacitor voltage at half of the battery voltage across the entire operating region of the EV. Therefore, a control method that switches between single inverter operation and dual inverter operation according to the operating conditions, and respond to changes in the capacitor voltage during operation switching is developed. The developed control scheme is demonstrated by hardware in-loop simulation and an experimental vehicle.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
