Overload Capability of the Modular Multilevel Matrix Converter for Feeding High Torque Low Speed Drives [PDF]

, 2014
In drive systems, the semiconductors of conventional converters must be dimensioned for the maximum torque. This results in a converter oversizing even for short time overload requirements near standstill, e.g. for mills in the mining industry.
