The function of pulsed capacitor
Pulsed capacitor is a device that store electric charge, mainly used for charge and discharge electric energy. Pulsed capacitors play a important role in the modern field of science and technology, ranged from power management to high-energy physics experiments, they play an indispensable role.
Fuction of pulsed capacitors
1.Protect Circuit
Since the untable voltage, capacitor is required in the circuit to protect the circuit from the shock of untable voltage. By charge-discharge from pulsed power capacitors, regulating voltage and current, so as to protect the circuit and other conponents from overvoltage.
2.Improve circuit efficiency
Pulsed-power capacitors are able to store electric energy, and release it when needed. Cousquently increase current and power efficiency. Even in high frequency circuit, the output power can be increased significantly by applying for pulsed capacitor.
3.Meet specific electric requirment
Pulse capacitors can provide a certain capacitance to meet the specific electrical requirements in the circuit. For example, in the transient phenomenon, the circuit needs the support of different voltage capacitors, then the pulse capacitor can provide the required capacitance, so as to meet the electrical requirements of the circuit
