The frequency of the AC input voltage plays a significant role in the design of capacitive voltage dividers. As mentioned earlier, the capacitive reactance of a capacitor is inversely proportional to the frequency. At low frequencies, the capacitive reactance is high, resulting in a larger voltage drop across the capacitors.
Therefore, the current flowing through a capacitive voltage divider is proportional to frequency or I ∝ ƒ. We have seen here that a capacitor divider is a network of series connected capacitors, each having a AC voltage drop across it.
We have seen here that a capacitor divider is a network of series connected capacitors, each having a AC voltage drop across it. As capacitive voltage dividers use the capacitive reactance value of a capacitor to determine the actual voltage drop, they can only be used on frequency driven supplies and as such do not work as DC voltage dividers.
A capacitive voltage divider is a circuit that uses a pair of capacitors parallel to the output and interlinked to the AC (Alternating current) input. You can get the ratio of the input and output voltage using the formula; V out /V in = 1/ (1+C S /C P) Where; C S represents the entire capacitance of the whole series-connected capacitors.
A frequency compensated voltage divider or attenuator is a simple two-port RC network providing a fixed voltage division ratio or attenuation over a wide frequency range and not just at dc. Such networks are used where the part of the circuit loading the voltage divider output is capacitive.
But just like resistive circuits, a capacitive voltage divider network is not affected by changes in the supply frequency even though they use capacitors, which are reactive elements, as each capacitor in the series chain is affected equally by changes in supply frequency.
