I have been trying to study the output characteristics of a thyristor based single phase AC voltage controller through the model in the picture attached. Could anyone tell me what I could do to achieve the output voltage(vout) characteristics by firing the thyristors at 30 degrees? I have used the pulse generator to trigger the thyristor with a supply frequency of 60 Hz.
I first set the period with respect to time base i.e; 0.0166 sec( because the frequency is 60 cycles/sec. therefore 1cycle or period=360 degrees=0.0167 sec) then I enter phase delay(ie;firing angle) as (x*0.0167)/360 where 'x' stands for your desired firing angle in degrees. if firing is required for negative cycle, then phase delay= ((x+180)*0.0167)/360.
