$begingroup$ Input to a voltage regulator is DC but a higher voltage than the output. The input to it is not AC. So how does this low impedance help? Or, are you talking about output from a bridge rectifier being connected to a capacitor shunted to ground and the output from that going into voltage regulator, since that would be a …
Capacitor banks in power system (part 1)
If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.. If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.
Capacitor Bank
An automatic capacitor bank is a device that, after detecting the presence of inductive reactive energy above the desired value in an electrical installation, acts by automatically connecting capacitor groups (steps) necessary to adapt to the demand and keeps the PF roughly constant (IEC 61921, 2017).
