How filter capacitors work is based on the principle of capacitive reactance. Capacitive reactance is how the impedance (or resistance) of a capacitor changes in regard to the frequency of the signal passing through it. Resistors are nonreactive devices. This means that resistors offer the same resistance to a signal, regardless of the signal''s ...

Capacitors play a crucial role in a UPS system by helping to smooth, filter, and store energy. A typical UPS contains dozens of different types of capacitors in both the main power section and at the printed circuit board (PCB) level. For the purposes of this whitepaper, our focus is on the former – the capacitors in the main power section.
