here is your answer.
double click on pulse generator block.
then first set the period with respect to time base ie; 0.02 sec( because in india frequency is 50 cycles/sec. therefore 1cycle or period=360 degrees=0.02 sec)
then enter phase delay(ie;firing angle) as
(x*0.02)/360 where 'x' stands for your desired firing angle in degrees.
if firing is required for negative cycle, then
phase delay= ((x+180)*0.02)/360.
hope it will help.

Hi,i want to know how to set the firing angle in case of pulse generators..
