Yes, I know what the circuit is for. What I want to know is what don't *you* understand about the circuit, what have you already done on the assignment, and what are you stuck on?
We will help you understand what you need, if you show that you are putting in the effort and trying hard. However, nobody here is going to do your homework for you.
And when S1 and S2 are both closed at the same time (assuming the top half of the bridge will work properly with the NPN transistors) you've managed to create a workshop heater
Well, that and the fact that he asked for an abstract.
Oops. I guess what he really asked for was an 'apstricat'. Damn I like that word. I wonder if ElectroMaster will change my username to that? (Kidding.)
If the OP had bothered to put in some effort I wouldn't have minded helping out but I didn't want to just spoon-feed him. Let's just hope the instructor notices when the assignment is a copy-paste from Wikipedia.
Well I have made a prehistoric H-bridge using relays, but I forgot to actuate them at the same time, and the safety diode. I have spent 2 hours, one finding the fire's source, and another wondering why I got shocked every time I touched the thing.
By the way, I have a noob-newbie question. Please, dont laugh

Why does the transistor blow up? The circuit is the old paralell port trick
