Single phase firing circuit for variable frequency-distorted voltage phase angle control

الملخص EN

The paper describes a simple and reliable single-phase firing circuit for phase angle control.

The input reference voltage may be of linear or distorted wave and of fixed or variable frequency and amplitude.

The output of this circuit is linearly controlled by a DC voltage over a range of 1-1000 Hz.

Another advantage of this circuit is the possibility of firing both thyristors or triac and extention to control AC converter or three-phase applications.
