Improving pulse handling capability of metalized polypropylene films capacitors

In this work, we tested the pulse withstanding capability of the MPPF capacitors. Although capacitors with long geometry seem to have a poor pulse handling performance, we found that the quality of the end-edge contact is strongly dependent on the physics features of the manufacturing process. The end edge contact plays a vital role in the pulse handling capability of the MPPF capacitors which varies from a few hundred to several dozen of thousand cycles discharging capability depending on the performance of the end-edge contact.
