What are the 4 stages of power supply?

Power Supplies

  • Transformer – steps down high voltage AC mains to low voltage AC.
  • Rectifier – converts AC to DC, but the DC output is varying.
  • Smoothing – smooths the DC from varying greatly to a small ripple.
  • Regulator – eliminates ripple by setting DC output to a fixed voltage.

How does computer power supply work?

A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input.
