随着电动汽车(EVS)数量的增加，需要有足够的充电基础设施来服务于这些车辆。新兴的极速充电(XFC)技术有可能提供类似于汽油车的加油体验。在本文中，我们回顾了最先进的电动汽车充电基础设施，并重点介绍了XFC技术，该技术将是支持当前和未来电动汽车加油需求所必需的。我们介绍了XFC站的设计考虑因素，并回顾了适合传输XFC的典型电力电子转换器拓扑结构。我们考虑了在XFC电站中使用固态变压器(SST)来取代传统的工频变压器的好处，并对XFC应用中的中压SST设计进行了全面的回顾。
With the number of electric vehicles (EVs) on the rise, there is a need for an adequate charging infrastructure to serve these vehicles. The emerging extreme fast-charging (XFC) technology has the potential to provide a refueling experience similar to that of gasoline vehicles. In this article, we review the state-of-the-art EV charging infrastructure and focus on the XFC technology, which will be necessary to support the current and future EV refueling needs. We present the design considerations of the XFC stations and review the typical power electronics converter topologies suitable to deliver XFC. We consider the benefits of using the solid-state transformers (SSTs) in the XFC stations to replace the conventional line-frequency transformers and further provide a comprehensive review of the medium-voltage SST designs for the XFC application.
