Goran Engdahl took the Master of Science degree in 1974 at Teknikum in Uppsala (Sweden). After this he was active in research regarding electric power engineering and electromagnetic wave propagation. From 1983 he was a project manager at ABB Corporate Research working with product development regarding electric power components, where several projects are related to applications with new magnetic and magnetostrictive materials. In 1987 he initiated the build up of a magnetics group at the department of Electrical Engineering at KTH. The intention of this group was to develop software design tools for electric power components based on data from material characterizations and new phenomenological modelling algorithms. The work of this group has for example resulted in an operative dynamic simulation software for highly magnetostrictive materials and a number of programs for magnetic hysteresis. From 1996 has been working full time at KTH and since 2001 as a professor in electrotechnical design is responsible for courses in electrotechnical modelling and electrotechnical design and supervises PhD projects modelling of electrical power components.
