This type of linear power supply has an extremely simple circuit consisting of a transformer, bridge rectifier, and capacitors. The transformer isolates and steps down the AC voltage, the ...

How many integrated circuits do you need to build up ... The end result is a very simple unregulated power supply — just a diode bridge with some capacitors on the output — but by using ...

We can see how circuits work, and represent them with some simple diagrams ... These could be batteries, solar panels, or a power supply connected to the mains - anything that can provide power ...
