Description

无级调压模块
技术领域
本实用新型涉及一种调压模块，特别是一种无级调压模块。 
背景技术
调压模块具有体积小、性能稳定、外围接线少、使用方便等优点，目前已广泛应用在许多电路控制系统中。如图2为目前家用电器上普遍应用的一种无级调压模块内部的电路原理图。由于普通无级调压模块电路中只有一级RC触发电路，工作时，只要电容C1损坏，整个产品就报废。因此，其可靠性较差。 
发明内容
本实用新型为解决上述现有技术产品可靠性较差的问题，提供一种新的无级调压模块，使其可靠性高。 
本实用新型所述无级调压模块，包括含有双向可控硅TRIAC的主电路，和连接于双向可控硅TRIAC的触发电路，其特征是：所述触发电路包括由DB3与电阻R1、电容C1组成的一级触发电路和R3、C2组成的二级触发电路组成。 
本实用新型所述无级调压模块，包括一双向可控硅TRIAC和双向二极管DB3，以及由电阻R1和电容C1组成的一级触发电路，其特征是：所述无级调压模块电路中还设有由电阻R3和电容C2组成的二级触发电路，其中R3接信号输入端1，且串接电阻R1和电容C2，而电容C2一端接电阻R1输入端，另一端接电压输出端3。 
本实用新型的有益技术效果是：所述无级调压模块内部电路设有由R1、C1和R3、C2组成的两级RC触发电路，在电路正常工作时两级RC触发电路可共同作用完成触发；如果C1或C2有一只损坏，导致一级RC触发电路不能工作，但另一级RC触发电路还可单独继续工作，从而保证产品能够继续正常使用。因此，本实用新型可靠性高。 
附图说明
图1为本实用新型电路原理图。 
图2为现有技术产品电路原理图。 
具体实施方式
如图1所示，一种无级调压模块，包括一双向可控硅TRIAC和双向二极管DB3，以及由电阻R1和电容C1组成的一级触发电路，其特征是：所述无级调压模块电路中还设有由电阻R3和电容C2组成的二级触发电路，其中R3接信号输入端1，且串接电阻R1和电容C2，而电容C2一端接电阻R1输入端，另一端接电压输出端3。 
本实用新型内部电路设有由R1、C1和R3、C2组成的两级RC触发电路，其R3按常规可设为可调电阻。主电路中的双向可控硅TRIAC分别接电压输出两端2、3，双向可控硅TRIAC控制极通过双向二极管DB3接两级RC触发电路。 
在电路正常工作时，信号输入端1输入信息，并且通过R3对C2充电，当C2两端电压上升到一定值时通过R1对C1通电；当C1两端的电压上升到双向二极管DB3的触发电压时，双向二极管DB3导通触发双向可控硅TRIAC导通，从而使电压输出两端2、3导通输出电压。当C1或C2都正常工作时，两级RC触发电路可共同作用完成触发；当C1或C2有一只损坏，导致一级RC触发电路不能工作时，而另一级RC触发电路还可单独工作，从而保证产品能够继续正常使用。因此，本实用新型可靠性高。 
应该理解到的是：上述实施例只是对本实用新型的说明，任何不超出本实用新型实质精神范围内的发明创造，均落入本实用新型的保护范围之内。
