【经验】浪涌保护中使用NTC热敏电阻ST系列和继电器并联
在浪涌保护一些电路中,我们可以看到一些继电器和NTC热敏电阻并联使用的电路,如下图所示:
由于NTC热敏电阻的特性是温度越高,电阻越低,正常情况下,常温下NTC热敏电阻阻值比较大,所以当电源刚开通时NTC热敏电阻具有抑制浪涌电流的作用,但当电流从NTC电阻流过后,NTC热敏电阻迅速发热,阻值急速降低,相对于传统的固定阻值限流电阻而言,电阻上的功耗因为阻值的下降随之降低了几十到上百倍, 因此这种设计非常适合对转换效率和节能有较高要求的产品。
但是NTC热敏电阻不能频繁的开关,因为电流从NTC热敏电阻流过后,NTC热敏电阻表面的温度很高,若想要NTC热敏电阻重新起作用,那必须要NTC热敏电阻从高温的低阻状态恢复到常温的高阻状态,为了解决上述问题,工程师就对电路进行了优化,在NTC热敏电阻并联一个继电器,这样产品上电瞬间NTC热敏电阻将浪涌电流抑制到一个合适的水平,然后产品正常工作后,继电器从负载电路得电后开始动作,将NTC热敏电阻从工作电路中除去。这样NTC热敏电阻只在产品启动时工作,当产品正常工作时是不接入电路的,既延长了NTC热敏电阻的使用寿命,又保证其有充分的冷却时间,能适用于需要频繁开关的应用场合。
LITTELFUSE的ST系列-浪涌电流限制器(功率型热敏电阻)是经过特别设计和加工的NTC热敏电阻,适用于在开关电源和需要避免较高的初始起动电流的其他应用中抑制较高的浪涌电流。 独特的设计使其能够处理极高的电流和电压水平。
ST系列最大连续稳态电流可达30A。最大浪涌电流下的电阻(RImax)最小进0.015Ω,最大工作环境温度为65℃。如果特定的应用要求工作环境温度超过65℃,也可提供定制设备,具体参数可以参考如下表格。
