Second-hand high voltage energy storage pulse capacitor

What is a pulse capacitor?

METAL CASES Pulse capacitors providing a wide range of capabilities for high peak current microsecond discharge to long life, high energy density applications. Capabilities PLASTIC CASES

What types of capacitors are used in pulsed discharge circuits?

Capacitors for use in pulsed discharge cir-cuits can be divided into two broad catego-ries. The first category is capacitors that use thin (5.5μm) aluminum foil electrodes to conduct current through the capacitors as shown in Figure 1.

How do you use a high voltage capacitor?

To achieve the best use of the dielectric ma-terial, it is necessary in a high voltage capac-itor to replace the air spaces between layers of wound dielectric and electrode with a die-lectric fluid. The addition of the fluid is done to decrease the stress across the space be-tween the solids and increase the break-down strength of this space.

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 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 factors affect the life of a pulsed power capacitor?

One major factor in the life of a pulsed power capacitor is the operating voltage. Here the performance is usually described in terms of a power law where: Where V2 is the operating voltage of interest and V1 is the operating voltage where the life characteristics are known.
