Voltage Multiplier Formula. As with the previous voltage doubler the diodes within the voltage tripler circuit charge and block the discharge of the capacitors depending upon the direction of the input half cycle. Therefore the total output voltage obtained in voltage quadrupler is 4vm which is four times more than the applied input voltage.
The output voltage closely follows the curve of an rc network as shown above. The impedance z of a capacitor is found by the formula z 1 2 pi f c where pi is the well known constant f is the frequency in hertz. A voltage multiplier is a specialized rectifier circuit producing an output which is theoretically an integer times the ac peak input for example 2 3 or 4 times the ac peak input.
Thus it is possible to get 200 vdc from a 100 v peak ac source using a doubler 400 vdc from a quadrupler.
The c 1 capacitor is charged through diode d 1 to u s v potential difference between left and right plate of the capacitor is u s positive peak u s. Any load in a practical circuit will lower these voltages. The last time around i looked at the cockcroft walton voltage multiplier. We will ultimately use this to build a cockroft walton voltage multipler and then we will examine the output characteristics of this multiplier.
