see application notes from Texas Instruments for UC3842

I don't understand the poll.

Bulding an SMPs can be both difficult and dangerous, probablky best to buy one off the shelf.

Hero999 is verymuch correct that it is dangerous and at times FATAL. Adquate precautions are needed. It wont be a game like playing with TTL circuits.

But perhaps it won't be difficult as some of the power electronics students have to design and realize it. If it not essential that Alfons SHOULD make it, it is preferable to purchase one.
