In combination with the newest IGBT power module generation, sub-millisecond fault interruption at current rates of rise up to 5 A/µs is reached. Insights in the design as well as electrical, thermal, and standardized short-circuit measurement results are presented. The design enables further innovation due to a 90% reduction in power module volume and weight in applications such as industrial facilities, data centers, renewable energy systems, and smart LVDC power distribution grids. This paper showcases its capabilities for a coordinated selective protection architecture in an 800 V DC distribution system with full short-circuit selectivity.
