Abstract - In this paper a new circuit design for the protection of e.g. multi level converters is presented. The so-called ‘optimized snubber design’ still comprises most of the positive features as a low number of components, improved efficiency due to the low snubber element and power semiconductor losses, reduced over-voltage across the semiconductor devices and no balancing problems. With theseadvantages, the new proposed snubber circuits can be used for high power inverters as well as the socalled Flexible AC Transmission Systems (FACTS). The presented snubber circuit has been analyzed and confronted with different existing converter designs using a simulation environment. The simulationresults are compared with the output of a standardized three level converter system to verify the advantages of the new snubber design. |
