Full Rectifier (UK Mains to 5V DC)

By Calum

This circuit converts UK Mains power (230V AC, 50Hz) to 5V DC. First it steps down the voltage then it rectifies the signal before smoothing it and putting it through a voltage regulator. Note that the 330V amplitude input is not a mistake, the UK mains runs 330V zero-peak, which gives an RMS (effective DC equivalent) of 230V.
