What it shows

  • Four diodes steer both halves of the AC wave into unidirectional pulses.
  • A reservoir capacitor charges at voltage peaks and discharges between them.
  • Higher load currents cause larger ripple voltages for a given filter size.

The takeaway

A bridge rectifier turns AC into pulsing DC, and a smoothing capacitor stores charge to flatten the ripple.
