The energy storage capacitor bank is commonly used in different fields like power electronics, battery enhancements, memory protection, power quality improvement, portable energy sources, high power actuators, ASDs, hybrid electric vehicles, high power actuators, off-peak energy storage, and military and aerospace applications.
Among all energy storage devices, the capacitor banks are the most common devices used for energy storage. The advantage of capacitor banks is, that they can provide very high current for short period. The operation of the capacitor bank is more reliable because of the use of advances in technology.
A typical low-energy storage capacitor bank schematic diagram is illustrated in Fig. 4.14. The bank consists of a capacitor bank of capacitance C s, a charging resistor Rc, a start switches S1, transmission line Tl, a crowbar switch S2, and a dissipating resistor Rd with an inductive load of L0.
The merits and demerits of energy storage capacitors are compared with the other energy storage units. The basic need of an energy storage system is to charge as quickly as possible, store maximum energy, and discharge as per the load demand.
Capacitor model Energy storage capacitors are commonly modeled as lumped RLC (resistor-inductor-capacitor) circuits. Here, equivalent series resistance (ESR) represents the resistive and dielectric losses in the capacitor, and equivalent series inductance (ESL) represents the inductance of the capacitor lead and current path through the capacitor.
Generally, switching to a capacitor bank uses spark gaps. A sole 2-ball spark gap is placed in series with the load as a result the capacitor charges as long as the gap is filled. Nowadays, a 2-ball spark gap consists of a triggering pin.
