为了增加现有网络容量，已经提出了将现有住宅低压电网电压从230 V提高的建议。然后使用电力电子AC-AC转换器在每个属性处提供230 V。诸如转换器位置处的温度上升的若干约束导致转换器设计需要非常高的效率。在本文中，沿着一个基于SiC的1 kW AC/AC原型模块的设计和测试，该模块构成了一个大得多的15 kW多模块转换器的基础，并介绍了一项关于LV网络容量增加的最新可行性研究结果。
A proposal to increase the existing residential LV grid voltage from 230 V has been made in order to increase existing network capacity. A power-electronic AC-AC converter is then used to provide 230 V at each property. Several constraints such as temperature rise at the converter location lead to a converter design requiring very high efficiency. In this paper results from a recent feasibility study in terms of LV network capacity increase are presented along with the design and testing of a SiC based 1 kW, AC/AC prototype module, which forms the basis of a much larger 15 kW multi-module converter.
