为了增加现有电网容量，提出了将现有住宅低压电网电压从230 V提高到300 V的建议。然后使用电力电子交流-交流转换器在每个属性处提供230 V。该设备还可以改善网络和负载的电能质量。转换器位置的温升等限制因素导致转换器设计要求非常高的效率。本文介绍了不同的AC/AC转换器拓扑结构，并比较了每种转换器的功率质量效益、尺寸和效率。通过仿真验证了最适合拓扑结构的设计和控制技术，并给出了样机硬件的初步实验结果。
A proposal to increase the existing residential LV grid voltage from 230 V to 300 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. The equipment can also provide power-quality improvements to the network and load. Several constraints such as temperature rise at the converter location lead to a converter design requiring very high efficiency. In this paper different AC/AC converter topologies are presented which compares the power quality benefits, size and efficiency of each converter. The design and the control technique of the most suitable topology are verified using simulation and preliminary experimentally results of prototype hardware are also included.
