Hello everyone, i have a big problem with simulink... I have a Half wave controlled rectifier with RL load and i wanted to set my thyristor to a gate degree of 30º. The problem is that i dont know how to do that. I tried using a pulse generator but i cant understand it. The amplitude there is in seconds, and phase delay also is in seconds and i need to have an gate angle of 30º (((( PLEASE HELP ME!!!!

You can make a phase shift on the gate voltage with a capacitor in series with a resistor.

 

30/360=ton/T

T=1/f

 

Thank you both, yes i could calculate it dang i better start studing.. but it would be nice if they made a wt scale since most power electronic studies uses alot of sin and cos fuctions..

 

thanks for ur work
