【产品】铭普光磁推出效率>99%的POE电源平面变压器用于5G POE电源,功率密度>30w/cm³
新一代5G技术提供了更高速度的互联网连接可能,助力实现各种IoT和大数据应用,给诸多网联产品创造新的商机。这些应用以更快的速度,推动将更多类型的受电设备(PD)连接到以太网网络的需求,包括IP监控摄像头、802.11ac和802.11ax接入点、LED灯具、5G小型基站以及其他IoT电器。
POE(Power Over Ethernet)是这些能量信号传输重要一环,它指的是以太网供电、IP电话、WLAN接入点、网络摄像头等小型网络设备,在传输数据信号的同时,直接从以太网线(4对双绞线中空闲的2对来传输)获得电力的技术。
由于PoE技术具有易维护、易安装、恢复期短、低成本等特点使得PoE市场分额在近几年一直呈大幅上涨趋势。POE市场按照终端类型来看主要分为工业、商业和住宅三种市场类型。
IEEE802.3bt新PoE标准发布之后,越来越多的高功耗终端设备开始应用到商业领域。在POE++应用的网络中,一台POE++交换机每个端口的最大输出功率为100W。如此,办公楼数字标牌展示器、销售点系统、液晶屏电视,以及电脑显示器等终端设备,就可以相互连接,构建一个POE智能系统。
另外,5G技术对智能家居概念的发展愈加深入,随之而来的是POE智能型家的出现,POE技术在家用方面的应用已经步入了新的阶段。POE智能型家指的是通过PoE技术将各类家用终端设备相连接,从而实现一种集中式管理。
何为“三高两低”?
5G网络技术的发展,对POE电源的技术要求提升明显,推动着开关器件、电路拓扑、控制技术进一步发展,对磁性元件的要求也越来越高,磁性元件发展基本呈现“三高两低”趋势。
高效率:降低损耗,参数最优化设计,提高效率。
高密度:提高频率,减小体积,集成化,实现高功率密度。
高可靠:结构简单,参数一致性好,可靠性高。
低价格:优化选材,自动化生产,降低成本。
低高度:降低元件高度,扁平化设计。
铭普光磁产品结构及优势
考虑到当前5G网络技术的发展,智能终端大量的应用,POE应用需求增大,加之磁性元件革新发展趋势,在市场与技术双边驱动下,铭普光磁开发了可应用于5G POE电源,具有低封装、高功率密度等优势的POE电源平面变压器,该变压采用高温、高频、低损耗铁氧体磁芯,绕组则采用扁平线圈、铜片和PCB进行组合。
该产品整体优势明显(型号TPEIR19-0150SG)
①功率密度>30w/cm3
②同功率体积小1/3,最大功率达150W
③损耗低,效率>99%
④耦合好,漏感小于0.5%
目前,这款POE电源平面变压器,已被广泛用于POE交换机、IP电话、监控摄像头、无线AP、物联网,以及IEEE 802.3af(PoE\POE+\POE++)应用的POE供电设备。随着人们对PoE应用需求的不断增长,PoE市场分额在未来十几年里还将持续扩大,PoE技术将为住宅、商业、工业等用户带来诸多便利。
