Voltage multipliers are the circuits where we get very high dc voltage from the low ac voltage supply a voltage multiplier circuit generates voltage in multiple of peak input voltage of ac like if the peak voltage of ac voltage is 5 volt we will get 15 volt dc at the output in case of voltage tripler circuitmultimeter only reads the rms root mean voltage value of ac voltage we. Apart from the high input imped­ance, this circuit has another advan­tage that when in­put voltage exceeds its limit, amplifier gets saturated which limits the current passing through the pmmc meter.
