National pulse energy storage capacitor

What is a capacitive pulsed power supply?

Capacitive pulsed power supply is considered one of the most stable and reliable energy source for electromagnetic launcher. Several PFUs are connected in parallel to form a pulse forming network (PFN), with each module operating in a sequential discharge mode.

What is a pulsed power supply?

As industrial applications place higher requirements on compact and portable pulsed power supplies, the National Key Laboratory of Transient Physics (NKLTP) recently developed a pulsed power supply consisting of a set of compact pulse-forming units (PFU), each with a capacitor energy storage of 220 kJ.

What is the main energy storage media in km capacitors?

Also, the major energy storage media in the type KM capacitors is Polypropylene while it is PVDF in the type LM capacitors. The list of references has information on the performance of some of the successfully de-ployed metallized electrode capacitor banks. A summary of the equipment discussed in the references is offered in Table 1.

What are the current requirements for pulsed discharge capacitors?

When defining current requirements for pulsed discharge capacitors, it is necessary to consider both the normal and fault condi-tions. If the fault current can be limited to about 10% of the shots and 3 times the nor-mal peak current, the normal conditions will drive the capacitor design.

What is a capacitor kHz?

capacitors are commonly found where the pulse rate is in the kHz range. Typically rep-rate applications require that the capacitors operate for life times in the millions of charge/discharge cycles. To accomplish this, the capacitors are run at relatively low energy densities.

What is a capacitor-based pulsed power supply (PPS)?

What’s this? Capacitor-based pulsed power supply (PPS) is widely used in fields related to electromagnetic launch, plasma, and materials' synthesis, modification and processing.
