The final result is an exclusive IGBT power module for an innovative circuit
concept. Its tailored design boosts the benefits of three-level power
converters by
n
increasing efficiency by reduction of semiconductor power losses;
n
improving reliability through lower electrical and thermal stresses;
n
reducing electromagnetic noise due to its intelligent circuit design.
