The design of power electronic converters for the integration of wind generated power into the grid is more and more important due to a new class of superconducting generators (SG) with power ratings of up to 20 MW. High efficiency of power converters for high-power applications is mandatory in order to reduce the overall cost of the system. This study proposes a design method to minimise the cost of the system by finding the optimal number of power devices and capacitors for different high-power converter topologies. The investigation focuses on determining the optimal number of voltage levels for a back-to-back (BTB) neutral point clamped (NPC) converter. The design method is demonstrated by estimating the cost of different BTB NPC power converter topologies for the integration of a 10 MW SG to the grid.
