Check out the rest of his videos as well. It’s because you want to learn something. Quibbling over circuit designs isn’t why you’re watching this video, though. (We would toss in a linear regulator somewhere.)

The output voltage of this circuit will depend on the average current drawn, but for basically static loads this circuit should work well enough, and the simplicity of just tossing gigantic capacitors at the problem is alluring. The end result is a very simple unregulated power supply - just a diode bridge with some capacitors on the output - but by using really big capacitors he gets down into the few-millivolt range for ripple into a constant load. (Hint: more is better.) And then it’s off to build. If you’re in the mood for a very well done review of diode bridges as well as half- and full-wave rectifiers, you should check it out.įirst off, goes through the basics of rectification, and demonstrates very nicely on the oscilloscope how increasing capacitance on the output smooths out the ripple. How many integrated circuits do you need to build up a power supply that’ll convert mains AC into a stable DC voltage? Would you believe, none? We just watched this video by (embedded below), where he builds exactly that.
