	I'm more concerned with Prahlad's comment - I don't really know how triacs work. Since He already pointed out so I didn't comment on it. It is not the case that you can't use PWM to drive a triac, but EMI issue can't be resolved without zero crossing detection. With PWM, you can conrol the average current through load but you can't reduce the peak current unless you switch at zero crsossing.
