Russian Electrical Engineering, 2012
A control singularity and basic characteristics of a combined matrix converter able to increase the output voltage in comparison with a traditional matrix converter are examined. Such converters maintain the rated parameters of an ac drive under mains undervoltage, which is especially important for “weak” mains.
