This section provides an overview for capacitor banks as well as their applications and principles. Also, please take a look at the list of 20 capacitor bank manufacturers and their company rankings.
Table of Contents
A capacitor bank is an assembly of multiple capacitors connected in parallel or series.
This allows for achieving large capacitance or high voltage. Capacitor banks are used in electronic circuits such as power supply units and pulse generators, aiding in the storage and supply of energy. Especially in applications requiring high current or high voltage, capacitor banks are indispensable.
Moreover, they are used in large-scale systems like power grids and railway vehicles to balance energy supply and consumption. The design of capacitor banks is carefully carried out based on requirements such as capacitance, voltage, and durability, as it significantly impacts the performance and reliability of the system.
