Abstract

This paper presents the design and reliability evaluation of metallized film capacitor for power e lectronics application. The rated voltage of development capacitor is DC 3300[V], the capacitance is 5 ${\mu}F$ and the ripple current capability is 130 $A_{rms}$. Film metallization and patterns are an important design factor that has been development enhance the electric and reliability properties of film capacitor for power electronics. In term of capacitor construction and metallized pattern is one of the parameters that can be modified to further improve the rating in the terms of maximum ripple current and lifetime. This capacitor can be used as snubber capacitor application such as power train invertor system.
