LITTELFUSE是一家专注于电子保护期间研发生产的企业。它生产的SIDACtor系列保护晶闸管可以应对过压工况下的电路防护。本文为读者介绍SIDACtor MC系列晶闸管推荐电路在开关电源初级保护中的应用,这款产品有着低容抗的特点,能够不影响后级防护电路宽频带的特点。

图 1 SIDACtor初级和5引脚保护器电路


上图为Littelfuse提供的初级保护方案,使用了的是装配有外部TOM和一对600R150自恢复保险丝(PTC)的P3203ACMC SIDACtor® 器件,其中如需自带过热保护机制的器件可以使用P6002ACMC SIDACtor®器件替代。虽然两种器件内部原理不同,但通过这种应用都能够为电路提供信号线和信号线、信号线与大地的防护,且都为TO-220封装,因此是可以替代的。该方案适合过电压保护工况,在过压工况下“输入”端被短路至各自的“输出”端,从而保护后级电路。

图 2 SIDACtor初级防护电路应用方法


上图2所示为Power Integrations公司提供的LinkSwitch-HP系列芯片提供的AC到DC的电源变换电路,这款电路在原设计上有着优异的性能,利用这个系列设计电源电路有高能效、高功率的特点,适合大功率电路的设计。如图所示,输入端为交流,通过整流滤波后通过控制芯片到达变压器初级,初级前端设计了红圈中所示的保护电路,在初级电压过压时二极管导通,钳位电压防止过压状况的出现。


上图是一个优秀的设计,但是在电源电路故障时,多数情况下会造成集成控制IC中的Mosfet管损坏,这种情况下就会出现过压的工况,图2中的防护电路主要应对这种状况,但是通过引入Littelfuse的SIDACtor系列晶闸管替代图2红圈处可以提高电路的防护等级。首先SIDACtor晶闸管的容抗很低,不影响原有电路的运行。其次在过压工况下可以在500μS内迅速动作,瞬态提供2.2A的通流能力,具备非常强的瞬态能量消耗能力。同时推荐电路还提供了大地接地端,为防护信号在各个防护路径上都提供了路径,在防护原理上更优。


图 3 产品外观和原理图符号(从左至右分别为P6002ACMC和P3203ACMC的原理图符号)


在此为读者提供TO-220封装MC系列的SIDACtor防护晶闸管P6002ACMC和P3203ACMC,P6002ACMC集成了两个晶闸管,P3203ACMC集成了三个晶闸管,产品通过了TIA-968、GR 1089、ITU K.20/21和YD/T标准,可以应用于多个行业,有利于产品认证。
