Abstract
Describes a comparison of a hard-switched IGBT-inverter and a symmetrical and an asymmetrical snubber circuit for IGBT-inverters using a minimum number of components. The two snubber circuits are optimally designed and they are compared to the hard-switched inverter with respect to switching times, switching energy losses in the IGBT and in the snubber circuit and the maximum frequency obtainable. In this way some guide-lines for using hard-switching and the two different snubber circuits are given
