High Energy Pulse Discharge Capacitors from China Factory - Reliable Suppliers for Oil-Immersed and Dry Types
General description
Pulse capacitor is capable of charge storage, and releasing a huge charge in a very short time. Our company can provide oil-immersed foil film type, metallized dry type, plastic case and other types of pulse capacitors for various purposes.
Structure and working principle of pulsed capacitor
Pulse capacitors usually consist of a layer of insulating medium sandwiched between two metallized plates/film. When this capacitor is charged, the charge is stored on the metal plate, and when the charge needs to be released, the capacitor is disconnected through an external circuit, so that the charge is quickly transferred to the other electrode.
Application of the pulsed capacitor
Pulse capacitors are widely used in high voltage, high current, high frequency circuits, such as radar, laser, controlled nuclear fusion, medical imaging, cardiac defibrillator and other fields etc. By controlling the charge and discharge process of the capacitor, a very short pulse signal of high voltage or high current can be generated to realize the function of the corresponding equipment.
