过零触发电路的应用与研究

Analyses and application of the Zero-cross-over Triggering Circuit

分析了过零触发电路的工作原理,介绍了过零触发电路在电镦机中加热电流的软硬件实现方法,并利用Labview进行了频谱分析。结果表明,过零触发电路具有对电源污染少,不含直流分量,具有一定的应用价值。

This article analyzed the principle of zero-cross-over triggering and introduced how to realize the software and hardware in the electric upsetting.Furthermore,it put up frequency spectrum analysis based on Labview.Analysis result demonstrated that the circuit made the power contaminate hardly and had some practice value without DC component.
