Hi, so i have built some amps and power supplies before , even some real simple smps from a working circuit schematic but I have two high power npn transistors laying around and some old half baked circuit boards.
I am interested can I make a real simple smps out of a 555 oscillator chip, and a few transistors , I took a basic A class design (I know it's an amplifier but most smps circuits are basically certain frequency amplifiers and their load is a transformer)
I made a multisim simulation about the schematic , the ne555 chip is simulated with the bipolar voltage source in the simulation.
I want to know what you think could such a circuit work?What elements would you add to make it better?
the main push pull npn transistors I would use would be BUX98A , I used these ones in the simulation because the database didn't have any more powerful NPN's.
