Abstract

An ever-growing demand of information technology (IT) services, cloud servers and digitalization has led to an exponential increase in the demand for digital storage, power demand, and energy consumption in data centres. In this paper, a smart transformer (ST) enabled triple-active bridge (TAB) converter for modern data centres is proposed. The smart transformer delivers power from medium voltage (MV) utility grid to low voltage (LV) ac load. The triple-active bridge (TAB) converter plays a pivotal role in supplying power from LVdc bus down to various low-level dc voltages required by the data centres. This ST enabled TAB converter offers several features such as reduced conversion stages, high frequency power conversion, connection of alternate power sources, higher efficiency, power density and reliability. The proposed system provides both ac and dc powers required by the data centre loads, and this can also be operated in UPS mode to ensure the continuity of power supply. The simulation is done in PSCAD/EMTDC software and the operation of the proposed system is verified.

智能变压器支持现代数据中心的三有源桥式转换器

信息技术(IT)服务、云服务器和数字化的需求不断增长，导致数据中心对数字存储、电力需求和能源消耗的需求呈指数级增长。本文提出了一种用于现代数据中心的智能变压器(ST)三有源桥(TAB)转换器。智能变压器将电力从中压(MV)电网输送到低压(LV)交流负载。三有源桥式(TAB)转换器在从LVdc总线向数据中心所需的各种低电平直流电压供电方面起着关键作用。这种ST支持的TAB转换器提供了几个功能，如减少转换阶段，高频功率转换，连接备用电源，更高的效率，功率密度和可靠性。系统提供数据中心负载所需的交流和直流电源，并可采用UPS模式运行，以确保供电的连续性。在PSCAD/EMTDC软件中进行了仿真，验证了系统的有效性。
