In this article, the modular three-phase ac–dc converter using single-phase isolated Ćuk rectifier modules for charging of electric vehicles is discussed. The converters are designed and analyzed for the continuous conduction mode (CCM). This article is based on a new concept of adaptive sliding-mode-based loss-free resistor (ASLFR). ASLFR is a control scheme, which allows dual aim of power factor correction along with tight voltage regulation; hence, the adopted topology serves as a fitting single-stage solution for balanced three-phase systems. Complete theory is developed for the application, and the effectiveness of the scheme is well-established. Various studies to confirm the robustness of the system to any load and line variation are carried out. Moreover, a qualitative analysis is also made to show the expediency of the proposed ASLFR. Simulation as well as experimental studies are claimed theoretically.

电动汽车充电应用中单级三相 PFC 转换器的无损耗电阻器仿真

在本文中，讨论了使用单相隔离 Ćuk 整流器模块为电动汽车充电的模块化三相 AC-DC 转换器。转换器针对连续导通模式 (CCM) 进行设计和分析。本文基于自适应滑模无损耗电阻器（ASLFR）的新概念。ASLFR 是一种控制方案，它允许功率因数校正和严格的电压调节双重目的；因此，采用的拓扑可作为平衡三相系统的合适单级解决方案。为应用开发了完整的理论，并且该方案的有效性得到了很好的证实。进行了各种研究以确认系统对任何负载和线路变化的稳健性。此外，还进行了定性分析以表明所提出的 ASLFR 的权宜之计。
