MKP Capacitors for DC-Link application in modern converters

摘要

Nowadays, new converter technologies demand higher performance to all involved components from semiconductors to passive components, in terms of both electrical and climatic operating conditions. DC-Link Capacitors are not an exception and challenging standards are being set to all technologies available, in which the reliability of the product is becoming more and more critical.rnIn this sense, film capacitors offer lots of advantages against other capacitor types. High current capability, low inductance, flexible design, different mounting possibilities, thermal stability, reliability and long service life make film capacitors a suitable solution for these applications. In addition, wherever much higher currents are required, 4-pin configurations are available, improving further the current handling capability of the standard 2-pin capacitors.rnEPCOS has understood the new trend and offers a wide range of MKP capacitors in different operating voltages, whose design and performance are described in this paper.
