【选型】Wolfspeed sic mos帮助实现LED驱动电源高效化,体积缩小1/3
LED驱动电源技术越来越成熟,市场对于电源体积价格要求也越来越高。150-200W驱动电源外壳也占有很大成本,较少外壳体积,提高驱动电源效率成为技术提升关键。WOLFSPEED公司SiC mos取代传统si mos方案,提高开关频率,减小变压器体积,从而达到电源整体成本的降低。
1、那么LED驱动电源关注系统成本应该从哪几方面入手?
(1)、更小的系统尺寸。势必要提高频率,减小无源器件体积。Wolfspeed sic mos取代传统si mos,损耗更低,散热器体积更小,整体体积可缩小1/3。
(2)、简化了设计,需要优化电路设计;
2、针对上述应用,Wolfspeed公司推出的SiC mos产品C2M0280120D,C2M0280120满足满足设计需求。
具有以下性能优势:
1)采用全新C2M SiC MOSFET技术
2)连续漏极电流最高可达10A,脉冲漏极电流可达20A
3)栅极阈值电压典型值为2.8V
4)导通阻抗典型值为280mΩ
5)最大耗散为62.5W,工作结温-55℃~+150℃,结壳热阻为1.8℃/W
6)抗闩锁效应,雪崩耐受性强

国内外做SiC mos管的厂家有哪些,都用在什么产品上?
目前国外厂商做碳化硅MOS管和碳化硅肖特基二极管比较好的有:Wolfspeed(科锐)SiC MOSFET选型,ROHM SiC MOSFET选型,Littlefuse(力特)等;国内的话现在批量生产SiC MOS的厂家还不太多,基本半导体,泰科天润等品牌世强都有代理。应用方面,碳化硅MOSFET在光伏、风电、电动汽车及轨道交通等中高功率电力系统应用上具有巨大的优势。碳化硅器件的高压高频和高效率的优势,可以突破现有电动汽车电机设计上因器件性能而受到的限制,这是目前国内外电动汽车电机领域研发的重点。

关于MOS管碳化硅的应用是否已全面成熟?
SiC MOSFET已有较多产品、也有很多成功应用。其高耐压、低损耗、高效率等特性,是相对于MOSFET的优势所在。然而,相对于以往的Si材质器件,SiC功率器件在性能与成本间的平衡以及其对高工艺的需求,仍是SiC功率器件能否全面普及的关键。世强代理WOLFSPEED(CREE POWER)的SiC MOSFET,Vincotech有集成SiC MOSFET和SiC二极管的功率模块,可在平台搜索“SiC MOSFET”或”SiC二极管“了解。
