Adjustable capacitor bank
Since both capacitor banks store the same total energy, the string with lower voltage has a greater percentage of charge wasted/unusable. In this case, the higher string voltage is preferable to fully utilize the SCs. A third system challenge arises when considering how to charge the SC bank. Initially, when the SC voltage is 0, SW1 has to work ...

Capacitor Banks: What is a Capacitor Bank? Advantages & Uses
A Definition. As the name implies, a capacitor bank is merely a grouping of several capacitors of the same rating. Capacitor banks may be connected in series or parallel, depending upon the desired rating. As with an individual capacitor, banks of capacitors are used to store electrical energy and condition the flow of that energy.
