电动汽车 (EV) 车主面临的挑战是，根据可用充电站，实际电动汽车车载充电器的灵活性有限。本文提出了一种基于可配置模块化多电平转换器（CMMC）的电动汽车统一转换器（UC）新概念，仅使用一个转换器进行快速充电和驱动系统。事实上，电机绕组在充电操作期间用作滤波器，并且电池组被分成子模块，以便模块化电池子系统。该概念使得车载独立快速充电器能够适应不同类型的电源（交流或直流，正常或快速）。另外，CMMC本身在与分布式发电（DG）并网过程中可以起到辅助服务的作用。此外，它的实现实际上很简单，因为它基于众所周知的三相控制[1]。然而，CMMC 需要具有公共中点的开放式交流电机。
Electric Vehicles (EVs) owners are challenged by the limited flexibility of the actual EVs on-board charger according to the available charging station. This paper proposes a new concept of a Unified Converter (UC) for EVs based on the Configurable Modular Multilevel Converter (CMMC), which uses only one converter for fast charging and for driving system. In fact, the motor winding is used as filter during charging operation and the battery pack is split into submodules in order to modularize the battery subsystem. The concept enables an adaptation of the on-board standalone fast charger for different kinds of power sources (AC or DC, normal or fast). In addition, the CMMC itself can play the role of ancillary services during the interconnection with the Distributed Generation (DG). Furthermore, its implementation is pratically simple because it is based on well-known three-phase control [1]. However, the CMMC requires an open-end AC machine with common middle points.
