ripple
Ripple

Full-wave ripple frequency is twice AC frequency

Voltage Doubler

On negative half-cycle, D1 charges C1 to Vp.

On positive half-cycle D2 adds AC peak to Vp on C1

and transfers it all to C2.

Voltage Doubler
  • Voltage doublers allow you to develop higher voltages without a transformer.
  • Stages can be cascaded to produce triplers, quadruplers, etc.
  • Voltage multipliers usually supply low currents to a high-resistance load.
  • Output voltage usually drops quickly as load current increases.
