What is a pulse capacitor?

A pulse capacitor is a type of capacitor that features solder lugs or snap-in terminals for connection and ensures constant pulse factors during large numbers of continuous discharges with short pulse repetition intervals. They have low leakage currents, making them energy efficient for the application.

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 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.

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 materials are used for pulsed power capacitors?

Over the past decade, there have been two major solid dielectric materials used for pulsed power capacitors. These have been kraft paper and Polypropylene. In recent years, Polypropylene has been used more than kraft paper for pulsed applications.

What happens when a capacitor reaches 0V?

When the switch turns off (connects to ground/0V), current flows to the left and discharges the capacitor. (The capacitor acts like a voltage supply.) The current stops when the capacitor reaches 0V. Short version: Pulsed DC is actually AC. *The charge and discharge are actually exponential decays, so mathematically, the current never really stops.
