摘要
在全数字三相全桥弧焊电源中,晶闸管的通/断控制是整个系统的关键环节,因此晶闸管触发角的计算显得至为重要。由于非线性运算DSP直接编程难度较大,论述了如何寻找一种灵活快捷、易于编程、并且精度较高的触发角计算方法,这对于提高触发电路的精度和可靠性是非常重要的。
In the all-digital three-phase full bridge arc welding power source,the on / off control of the SCR is the key to the whole system,so it is more important to the calculate the triggering angle.And due to non-linear DSP operations is more difficult than the direct programming,it is also important to find a flexible and fast,easy programming and the high precision triggering angle calculation method to improve the accuracy and reliability of the trigger circuit.
