Honestly, people tend to think this stuff is trivial, and can be explained in a sentence or two, but with h-bridges in the 15A range, you have no idea what you're getting into.
You would do well to heed this advice.
That's why I'm asking here is someone can either explain this kind of stuff or knows of any good resources.
