What is energy storage capacitor bank?
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.
Can a capacitor bank provide a high current?
A large capacitor bank is designed to provide a peak current of range 10-15MA at the rate of 10 12 A/s. A single spark gap cannot supply such a high current. Spark gaps with low jitter are used in parallel for high current applications. Generally, the design of a capacitor bank needs a separate spark gap.
