Hey guys. I'm not supposed to ask about homework stuff in this forums but I'll give it a shot cause I'm really really lost in this. Also, I won't be so specific. I'm taking the power electronics course from college and I'm supposed to give a presentation on Opto triacs. I just don't know where to start, I don't get to understand what is the use of this component. Every time I search for it I just get lots of acronims and I don't know which one is really the device I'm looking for. I shall say that my experience with analog electronics wasn't really good. I know what a transistor is, what a diode is, I have some idea of how JFET transistors work, I know how to do some math as well, in fact, I don't have too much trouble with semiconductors. However, all this power things are really new to me. Any help I could get will be really apreciated.
