解决方案
Stringent international standards require that Server and Telecom power supplies provide higher efficiency and power density, greater robustness, increased flexibility and a set of features to ensure the power delivering system can be constantly monitored. These design challenges require engineers to identify innovative solutions when it comes to topologies and implementations with semiconductor products being key enablers. ST offers a broad product portfolio including silicon-carbide (SiC) diodes and power MOSFETs, high-voltage MDmesh™ - for PFC and DC-DC stages – and low-voltage STripFET™ power MOSFETs - for the synchronous rectification stage - STDRIVE MOSFET gate drivers as well as a comprehensive portfolio of switching controllers, and innovative solutions for direct 48 V to point-of-load (POL) post-regulation for CPUs, memories and ASICs supply to help achieve the highest overall efficiency 

以太网供电 (PoE)
Power over Ethernet (PoE) is a widely adopted technology used to transfer power and supply the powered device (PD) including wireless access points, VoIP phones and even LED bulbs over an RJ-45 cable also carrying data as described in the IEEE 802.3

服务器和电信用直流-直流供电装置
为了支持云服务、物联网和移动应用的进化发展，人们对数据中心的需求呈指数级增长（希望CPU越来越强大，存储器组的容量越来越大），使得如何确保高效率、高功率密度和高可靠性成为令人生畏的挑战。  在典型的架构中，AC-DC电源设备生成48V直流轨，然后将其转换以提供一定数量的直流电源轨，以便为服务器中各种负载和电路供电。这种转换必须满足严格的效率目标，因此需要创新型架构，如电源模块联盟（PSA）开发的架构（可以从48V电源轨进行直接转换）。
