提出了一种基于电流源型变流器（CSC）的V2G拓扑结构，该拓扑结构由电流源型整流器（CSR）和辅助开关网络（CSW）组成。该拓扑结构在可编程逻辑器件的帮助下，演化为五种电路结构，并可分别工作在降压充电、升压充电、降压放电、升压放电和无功补偿五种模式下。因此，它不仅可以适应更宽范围的电池电压，而且可以在必要时向电网提供电压支持。为了便于分析，建立了统一的数学模型来描述5种运行模式，并提出了基于自抗扰控制思想的统一控制方案来管理相关的充放电过程。实验结果验证了所提出的拓扑结构和控制方案的正确性和有效性。
In this paper, a topology based on current source-typed converter (CSC) is proposed for vehicle to grid (V2G) application, which consists of a current-source-type rectifier (CSR) and an auxiliary switching network (ASN). With the help of ASN, this topology is evolved into five circuit structures, and then could be operated in the corresponding five modes: buck charging, boost charging, buck discharging, boost discharging, and reactive power compensation. Therefore, it not only can adapt to a wider range of the battery voltage, but also can provide voltage support to the grid if necessary. For the ease of analysis, a unified mathematical model is established to describe the five operating modes, and a unified control scheme based on active disturbance rejection control (ADRC) idea is proposed to manage the related charging and discharging processes. Experimental results verify the correctness and effectiveness of the proposed topology and control scheme.
