摘　　要：为有效解决目前数据中心供电系统投资高、设备利用率低、通用性差等问题,现提出一种嵌入式电源解决方案,即结合市电混供技术,在设备侧新增嵌入式电源,当市电电源满足要求时由市电220V转12V/48V直接给设备供电,当市电电源出现故障或电源质量不满足要求时,系统自动转由336V/240V直流电源系统降压12V/48V后,给设备供电,实现灵活供电的需求。in order to effectively solve the data center power system problem of high investment and low utilization rate of equipment,and poor generality, now put forward a kind of embedded power solutions, combined with grid technology, namely in the equipment side new embedded power, when the mains supply meet the requirements by the mains 48 v directly to turn 12 v/220 v power equipment, when the mains supply fails or when power quality does not meet the requirements, the system automatically turn by a 336 v/240 v dc power supply system after decompression for power supply equipment, realize the flexible power supply requirements.
