What is a power capacitor, its basic structure, performance characteristics, working principles, applications, causes of damage, operating procedures, and market prospects 2

3、 Working principle:

The working principle of power capacitors is to utilize the electric field effect to store electrical energy in the capacitor. When a capacitor is powered on, charges accumulate between the metal foils of the capacitor, forming an electric field. When the power is disconnected, the charges in the electric field will be released and provided to the power system for use.diode
