【经验】对交流电感电路进行电弧抑制的几种方法
LITTELFUSE是电路保护领域的全球领先企业,提供种类最多、范围最广的电路保护产品组合,向业界提供最广泛且最尖端的电路保护产品及解决方案产品组合,本文通过其推出的SP1103C系列80A离散型双向瞬态抑制二极管来说明交流电路电弧抑制的几种方法。
使用簧片开关或簧片传感器来控制感应装置(继电器线圈、螺线管、变压器、小电机等)时,当簧片开关打开时,存储在装置中电感的能量将使开关处于高压状态。当开关触点打开时,接触间隙最初很小,在开关打开后,可以立即产生一个通过接触间隙的电弧。这可能在电阻和感应负载中发生,而感应负载会产生更高的电压,这会导致电弧增加,而电弧放电会降低开关寿命。
直流(DC)电感电路通常使用二极管来防止高电压。电路中的二极管被称为抑制二极管、反激二极管、续流二极管或捕获二极管。
图1 带抑制二极管的直流电流
然而,二极管不能在交流(AC)电路中使用。交流电弧抑制需要使用金属氧化物压敏电阻器(MOV)、双向瞬态电压抑制器(TVS)二极管或RC抑制电路(RC缓冲器)。各种电弧抑制方法各有其优缺点,如果器件有足够长的使用寿命,也可以不对电弧进行抑制,具体使用哪种方法需要综合考虑成本、接触寿命、封装等因素。
当超过阈值电压时,MOV和TVS二极管导通电流。这些器件通常与开关触点并联且可以在较低的电压下工作,例如24VAC,也可以用于120 VAC的较高感应负载。MOV器件的电容大于TVS器件。如果使用MOV,则应考虑MOV电容的影响。

Littelfuse推出的SP1103C系列80A离散型双向瞬态抑制二极管可为电路设计师提供更低的断态电压,用于保护低压电源总线免受静电放电(ESD)的损坏。这种二极管采用专有的硅雪崩制造技术以瞬态抑制二极管构成,可保护每个I/O引脚,为对破坏性ESD高度敏感的电子设备提供高水平保护。该二极管功能强大,可安全吸收±30kV的反复性ESD震击而不会造成性能减退。此外,每个二极管还可在极低的箝位电压下安全耗散80A的8/20μs波形浪涌电流。应用于汽车电子设备、工业产品、消费电子产品、开关/按钮、测试设备/仪表、销售点终端、医疗设备、笔记本电脑/台式机/服务器和电脑周边设备。
交流电弧抑制还可以使用RC抑制电路(缓冲器)。RC抑制电路的优点是,当接触间隙很小时,在开关打开时限制开关接触电压。RC抑制电路也可以用来减少电弧并提高电阻负载的使用寿命。在RC抑制电路下,串联电容和电阻网络与开关触点并联,或者,可以将电容器和电阻器放置在负载两端。将RC缓冲器放置在开关触点上是首选,但这样做的缺点是,当开关打开时,需要通过缓冲器提供通向负载的电流路径。将缓冲器放置在负载上可以消除电流,但布线和源阻抗的变化可能会改变电弧抑制的效果。
图3 跨开关触点的RC(缓冲器)抑制
在缓冲器中使用的电阻值和电容值需要进行权衡折中。当开关触点闭合时,电阻值必须足够大以限制电容放电电流,但当开关触点闭合时,电阻值必须足够小以充分限制电压。当开关触点断开时,较大的电容值降低了电压,但也付出了更高的代价,同时增加了开关触点闭合时的电容放电能量。
图4 跨负载的RC(缓冲器)抑制
要选择近似电阻值,请使用欧姆定律:
V=I*R,即R=V/I。R应在0.5*Vpk/Isw和3*Vpk/Isw之间选择,其中Vpk是AC峰值电压(VRMS*1.414),Isw是簧片开关或传感器的额定开关电流。较低的R减少了电弧放电引起的接触损耗。较高的R减小了电容性浪涌电流引起的接触损耗。
可以通过多种方式评估所选缓冲器的性能,比如计算或模拟。然而,负载的电感和电阻特性可能并不是精确已知的——机电负载的电感随机械部件位置的变化而变化。
1. 建议使用示波器评估开关触点之间的电压波形,特别是在触点断开期间。缓冲器可以减少或消除触点闭合和触点断开之间产生的电弧。触点断开后,电压升高,上升电压不会重新进行电弧接触。此外,缓冲器电容器上的最大电压不应超过电容器的额定电压。
2. 对于簧片开关,另一种评估缓冲器是否有效工作的好方法是查看开关接触间隙中电弧产生的光强度。光强较弱即电弧能量较少,表明寿命较长。
3. 最后也是最准确的评估性能的方法是进行寿命测试。接触寿命与开关周期的数量有关,而不是与供电或非供电小时的数量有关。对于电弧负载的寿命测试,建议的最大每秒操作数是5到50次(最大值,5-50Hz)。最大测试率取决于电负载与准确性之间的平衡。
当确定缓冲器的元件规格时,除了前面提到的对电弧评估、最大电容器电压和寿命的检查之外,还有其他一些方面需要考虑。当开关触点打开时,电流将流过缓冲器,所以应该验证这种“漏”电流在应用中不会引起问题,并且缓冲电阻中的功耗不会超过额定功率。此外,另一个考虑因素是RC缓冲器可以与双向TVS二极管或MOV结合使用。缓冲器更有效地限制开启触点的初始电压。TVS或MOV可以更有效地限制峰值电压。

【技术浅谈】TVS的选型计算你做对了吗?(续)
TVS的选型计算介绍。上一篇写的计算方法针对的是单次的浪涌,比如Surge test一般两次浪涌之间会有30~60 s的间隔时间,这意味着TVS有足够的时间去把吸收的浪涌能量给耗散掉,不会因为热累积而导致TVS温度过高而损坏。但是,现实中还有一些情况是会有重复浪涌的。

【应用】TVS SM712-02HTG应用于RS422通讯保护,容值低至75pF
RS422接口是采用差分方式传输数据,基于电平是±6V,AB的共模电压在±7V之间。当有浪涌冲击时,感应雷需在ns级的状态下进行吸收,故为了降低TVS容值对1.25Mhz频率信号真实度的影响,TVS的电容值选择尽量在pF级别。Littelfuse的SM712-02HTG为+12V/-7V TVS,钳位电压是专门针对RS422这类电平应用设计的电压,另外该TVS的容值低至75pF。
