DC to DC converter
for electronics A level coursework i am hoping to build a DC to Dc converter to use to power high power leds. As far as i understand it will convert DC to AC, use PWM to alter the current out, and then convert this back to DC giving a constant current out. These are available in devices (known as buckpucks) but for my coursework i hope to build a similar thing on Breadboard.
This is really a question for the engineers and if they could give me some advice on anything to do with this it would be great!
