【选型】600w车载DC-DC变换器后级整流电路中推荐肖特基整流二极管SBT60100CB,具有低功率损耗、高效率的特点
车载直流电源上接的DC/DC变换器是把高压的直流电变换为低压的直流电,用途就是将整车动力电池300VDC或者540VDC转化为12VDC或者24VDC,供整车低压用电器工作,同时具备给铅酸蓄电池充电的功能,故DC-DC是电动汽车不可或缺的一个关键零部件。
如下图1,是600W车载DC-DC常用电路拓扑,前级输入高压,经过开关管变换后,在后级整流电路中,通过整流二极管整流后可输出12V/24v给整车低压电器供电,这里主要介绍整流输出12V电路用到的肖特基二极管。
图1、600W车载DC-DC常用电路拓扑
后级整流电路中,需要选择合适电压的整流二极管,12V电压系统,需要选用反向耐压100V规格的,根据功率选用可过流60A的,这里推荐强茂的肖特基整流二极管SBT60100CB,其参数如下图2,可知在后端整流的运用中可满足应用需求。
图2
同时SBT60100CB还有几个显著特点是具有高浪涌电流能力,IFSM达到320A;正向导通压降VF=0.86v@If=30A,可降低功率损耗、提高效率,-55℃~150℃,具有宽的工作温度范围,适应整车恶劣环境。
综上描述可知在600W车载DC-DC的运用中,强茂的SBT60100CB可满足运用需求。

【选型】智能插座应用中选择肖特基整流二极管SBA520AF,具有功率损耗低、效率高等特点
市电经过变压器→整流二极管→功率电感→DCDC/LDO给主控单元供电,主控单元可以从电量检测的信息中了解到电器的使用情况,通过控制继电器的方式控制电路的通断。由于主控单元的输入电压需求较低,一般为10V以下,功耗最高也为毫安级别,因此可选220V转10V(或更低)的变压器。市电经过变压器降压后,需要整流二极管将交流电转换为直流电。因此,本文推荐PANJIT的肖特基整流二极管SBA520AF。

开关电源双管正激,输出整流二极管该如何选用
开关电源的输出二极管,一般会选择快恢复二极管或者肖特基二极管,首先需要确认电源的开关频率,频率越高,反向恢复时间则需要越短,其次是输出电压,由于肖特基二极管电压基本在200V以下,所以一般低压输出低Vf要求,推荐肖特基二极管,输出是高压,推荐快恢复二极管,世强电商平台目前代理的主要二极管品牌有Diotec,新电元和强茂,这些都是专业的二极管品牌,DIOTEC的资料参考:【选型】Diotec(德欧泰克)SMD封装的二极管/整流器 选型指南;新电元的资料参考:【选型】Shindengen(新电元)功率器件选型指南;强茂的资料参考:【选型】PANJIT(强茂)SiC肖特基二极管/整流器/MOSFET/保护组件快速选型表。

【应用】超快恢复肖特基二极管MBR6200在反激式开关电源充电器的应用
AC/DC反激式开关电源选用整流二极管应优先使用工作频率高,能承受反向脉冲3倍以上超快恢复肖特基二极管,不能使用普通整流二极管。因为开机瞬间时的峰值电流,以及反向峰值电压可能会超过你二极管的额定值。很容易击穿短路。选用强茂(PANJIT)新型MBR6200超快恢复型整流二极管。反向恢复时间短。新型肖特基在热和提升效率的问题一直保持业界领先水平,已经大量应用AC/DC充电器产品出货10KK以上 。
