6 FAQs about [Pulse Test Capacitors]
How many pulses can a capacitor withstand?
The test of the pulse loading capability consisted of exposing the samples to pulses in a series of 5 pulses of the same amplitude. Ten pieces from each batch were tested. The proposed criterion is that the capacitor would withstand at least 5 pulses during the test.
How does a pulsed power system affect a capacitor?
In pulsed power systems, capacitors face near-to-breakdown operational voltage. Pulse loads increase the dynamics of heat generation or mechanical load, which have complex correlations to DC breakdown strength of the capacitors , , , , . Over a discharge field onset, a significant heat is generated in the capacitor structure.
