技术问答

在电源设计中将380V的三相电经过整流和滤波转换为650V的直流电压，本文推荐在半桥电源拓扑设计中，可以经过副边SMC的肖特基整流器 MBR60200W整流和调理电路输出固定功率的直流电源，满足一些工业特种设备的电源需求，如工业电炉，电解电镀装置等。如图一半桥式电源拓扑设计常用于上千瓦的电源系统应用中。

根据MBR60200W的引脚图显示，该肖特基整流器在封装方面保持了TO-247两脚设计，与现在主流的TO-247三脚封装相比能满足了不同设计需求。内部集成了单个二极管，PN结工作温度可达150℃。同时设计时为满足过大电流需求插接引脚末端做了加宽处理。推荐MBR60200W的指标优势如下：

1、 TO-247AC封装便于安装替换；

2、平均正向整流电流达75A，满足大功率输出;

3、正向压降低至1V，具有更小的功耗，使用寿命更长。

综上所述，SMC的肖特基二极管MBR60200W采用TO-247AC的两引脚设计便于安装替换，且满足大功率输出，适合用于半桥电源拓扑设计。
