功率高达150kW的充电设备
用可扩展的直流充电，填补住宅和高速公路充电之间的空白
如今，电动汽车（EV）的车主不再仅限于城市居民或短途通勤人员。正因如此，电动汽车的充电也不再局限于住宅或办公室。尽管高达350kW的大功率直流充电器给高速公路带来了快速充电的机会，但其实在城市中，150kW的充电器才是日常会用到的理想解决方案，它填补了住宅和高速公路充电之间的空白。
考虑到150kW电动汽车快速充电器的模块化设计及其可扩展选项，它正成为城市地区和商业应用的首选。一个50kW的充电模块可实现充电48分钟左右，续航200公里，而如果通过并联三个这种50kW的充电模块或5个30kW的充电模块，使之成为一个150kW的充电设备的话，则可在大约16分钟里，经济高效地进行相同续航里程的充电。尽管不论哪种并联选项，16分钟对于稍事休息的司机而言都太久了，但这刚好够他们来购买一些杂物或用餐，同时能够便捷地完成充电。

技术趋势
额定功率在30 kW-150 kW之间的电动汽车充电系统通常依赖于两级电源转换结构，即电网侧的AC-DC电源转换级和电池侧的隔离高频DC-DC电源转换级。它将15 kW到30 kW的基本充电模块并联起来，以提供高达150 kW的功率。这些低功耗充电模块为系统增加了功能方面的模块化性能，从而实现了采用分立功率器件的变流器设计，十分经济高效。您可在此探索150 kW电动汽车充电设备的系统图：

拓扑结构和电源转换
在AC-DC转换级，AC-DC转换系统在EMI滤波器之后，发挥着受控整流器的作用。在这个级别，首选二级有源前端（AFE） 或三级Vienna整流器拓扑。这两种拓扑结构都能够根据充电器的额定功率，确保稳定的直流链路电压（最高可达900V）。特别是Vienna整流器，它以其更高的效率和更柔和的EMI特征，而被广泛使用。此外，它还支持使用600V功率器件。得益于1200 V CoolSiC™ 等元器件，具有功率因数校正（PFC）拓扑结构的二级有源前端变得越来越受欢迎，其双向操作的特点更是使之独具魅力。
在DC-DC转换级，分为两个系统：在隔离变压器初级侧，从DC电压转换为高频AC电压；在次级侧，从高频AC转换为DC电压整流。适用的拓扑结构通常为谐振式、硬开关全桥式、移相式、ZVS、全桥转换器。具有单桥（1200 V SiC）或级联桥（600 V）的谐振LLC转换器拓扑结构被广泛应用于该电源转换级。
