The circuit given in figure has a voltage output three times greater than the input voltage. The capacitor's characteristics are calculated as follows:
Formula 1
Voltage in the capacitors:
Uc1 = Umax
Uc2 = µC3 = 2 x Umax
Where:
Uc1, µC2 and µC3 are the minimum working voltage DC (WVDC) of the capacitors in volts (V)
Vmax is the peak of the input AC voltage in volts (V)
Note: Minimum PIV of the diodes is 2 x Umax.
