如何用二极管实现不同电压的输出?
利用二极管的单向导电性可以设计出好玩、实用的电路。分享本文,分析限幅电路和钳位电路,是如何用二极管来实现的。
限幅电路
如下图所示,当在正半周期,并且VIN大于等于0.7V,二极管正向导通。此时,VOUT会被钳位在0.7V上。而当VIN小于0.7V时二极管是截止状态,在负半周期时相当于电流反向,二极管也是截至状态,此时VOUT=VIN,VOUT波形跟随VIN变化。
限辐电路示意图
根据上面限辐电路的原理,可以设计如下双向限辐电路。
双向限辐电路示意图
然而有时候0.7V电压不能满足要求,那么,怎么产生不同大小的限幅电压?在电路中加入偏置电压VBIAS,只有当VIN大于等于VBIAS时二极管才能导通。此时VOUT被钳位,其值是0.7V+VBIAS,如下图所示。
偏压限幅电路示意图
钳位电路
下面是二极管结合电容实现的钳位电路。分析中不考虑二极管的导通压降,假设RC时间常数足够大,从而使输出波形不会失真。
钳位电路原理
当输入Vin在负半周期为负时,电流如下图中红色箭头所示。二极管导通,电容逐渐充电至V,在此过程中Vout=0。当输入Vin在正半周为正时,电流如蓝色箭头所示。二极管截止,Vout等于电容上电压加上正半周电压V,此时Vout=2V。
钳位电路原理
偏压钳位电路
跟限幅电路类似的,为了获得所需要的钳位值,要在电路中加入偏置电压,如下图所示。
偏压钳位电路
当所加的偏压与二极管导通方向一致,钳位值会提高V1,Vout=2V+V1。
双向二极管钳位电路应用举例
在某些电路中会利用两个二极管的钳位作用进行保护,如下图所示,假设0.7V为D1和D2的导通电压。
Vin大于等于Vmax,D1导通,Vout会被钳位在Vmax
Vin小于等于Vmin时,Vout被钳位在Vmin

一文详解二极管压降的定义、数值及影响因素
二极管压降是二极管在正向导通和反向截止状态下电压降低的现象。其数值取决于多种因素,包括材料、类型、工作电流和温度等。在实际应用中,了解二极管的压降特性对于电路设计和分析具有重要意义。对于需要低功耗和高效率的电路来说,选择压降较小的二极管尤为重要。

如何外观检测静电二极管的好坏?
静电二极管主要用于保护电路免受静电放电的损害。静电二极管是一种保护元件,通过在电路中提供路径引导过高的静电电流,从而保护敏感元件免受损害。然而,静电二极管在长时间使用或过度静电放电事件后可能会损坏,因此,外观检测成为了判断其是否仍然正常工作的一种简单且有效的方法。本文中辰达行来为大家介绍如何外观检测静电二极管的好坏,希望对各位工程师朋友有所帮助。

二极管有什么特性
二极管是电子元件当中一种具有两个电极的装置,只允许电流由单一方向流过,目前在电路应用中比较常用的就是它的整流功能,当然像肖特基二极管,开关二极管也是它重要的用途。二极管最普遍的功能就是只允许电流由单一方向通过(称为顺向偏压),反向时阻断 (称为逆向偏压)。因此,二极管可以想成电子版的逆止阀。本文我们主要了解一下二极管特性有哪些?

【经验】如何通过热特性正确推导二极管结温以及尽量降低结温提高产品寿命的建议
基于硅材料的二极管被广泛用作保护或者整流元件,当二极管用在大功率电路,电流达到5A 以上往往需要轴向二极管,我们常用的方法就是把轴向产品的引线进行弯脚成型,以便通过波峰焊焊到PCB板或接头处。 为了确保这些设备的安全运行,我们需要精确掌握二极管热特性。本文以首先说明二极管的热特性,然后再通所讲热特性参数来正确推导结温,最后提出如何尽可能降低结温提高产品寿命的建议并推荐德欧泰克的X系列产品。
