1.Energy Storage,Pulsed,DC-Link Filter Capacitor The capacitor can be charged in a long time and discharged in a very short time, thereby creating a huge pulse of power. The pulse power is obtained by charging the pulse capacitor bank.Then, the pulse capacitor bank is charged by charging device with small power for a long time before the experiment, and the shock discharge is only tens of milliseconds, which greatly improves the economic efficiency. Furthermore,it has resin filled,self-healing property,long life time and good high frequency characteristics. 2.Applications (1)Used in rail transit traction or ship drive converter. (2)Used in various high-power industrial inverters,such as high-voltage variable frequency drive device. (3)Used in power harmonic governance and SVG equipment.
