Voltage Doubler Calculator
Calculate voltage doubler circuit parameters, component values, and output characteristics. Design and analyze voltage multiplier circuits for your electronics projects.
Step 1: Circuit Parameters
Voltage Doubler Types
Half-wave doublers use 2 diodes & 2 capacitors. Full-wave doublers use 4 diodes & 2 capacitors. Cockcroft-Walton multipliers can achieve higher multiplication factors.
Step 2: Components
Component Selection
Higher capacitance reduces ripple voltage. Fast recovery diodes are recommended for high frequency applications. Voltage ratings should exceed calculated peak voltages.

Voltage Doubler Formula
Vout = 2 × (Vin_peak – Vdiode) – Vripple
For half-wave doubler: Vout = 2×(√2×Vin_rms – Vd) – (I_load / (f×C)). Full-wave has less ripple. Cockcroft-Walton: Vout = N×(√2×Vin_rms – Vd) where N is number of stages.
