He used a thyristor that meets spec (and is the main controller of current in the circuit (800V / 50A) vs transistor 1 (250V / 40A).
So i feel like he’s done a pretty decent job of problem solving on this one - especially for a first time poster! Who knows, it might be him helping us figure out a thorny problem not too far down the road… |
This is not the only key SCR parameters needed, e.g. have the turn-off time and current been forgotten? It's not as simple as some have indicated for reliable functionality!
