Circulation power test run of 1MVA 3-level NPC Power-Stack:

Dec 10, 2015

At Danfoss Silicon Power GmbH in Flensburg senior engineer Dr. Toke Franke and PhD student Berthold Benkendorff tested the 1MVA three-level power-stack inverter out of the "innovation cluster project" for wind power application at more than 800kVA in a circulation power test.



  • Our research is focused on the design of high efficient and reliable PWM-based power converter architectures (single-cell, multi-cell, multilevel), their modelling and control to exploit commercial as well as new power semiconductor devices with minimum over design.
    We develop controllers for electric drives and we are particularly skilled in the integration of renewable energy systems into the electric grid.
