Abstract
This paper studies the application of common-mode voltage injection techniques typically used in two-level inverters (carrier-based space-vector modulation and flat-top modulation in particular) to quasi-two-level PWM-operated modular multilevel converters. Similar to two-level inverters, the available operating area is extended to higher modulation indices. The properties of the respective techniques are compared to each other and to the modular multilevel converter in the normal operation mode. The results are based on simulations and the model is partly experimentally validated on a downscaled converter prototype.

T1 - Common-mode voltage injection techniques for quasi-two-level PWM-operated modular multilevel converters
AU - Kucka, Jakub

N1 - Funding Information: Additionally, the paper has shown that the upper IGBT/ diode switch in modules has significantly lower losses than the lower switch, when the quasi-two-level PWM operation is applied. In future work, the option to decrease the size of this switch will be investigated. Furthermore, the control implementation used for the converter prototype will be presented and the application of quasi-two-level PWM-operated MMC to medium-voltage low-speed drives will be studied more extensively, drawing a comparison to other converter topologies and operation modes.
