Quasi Two-Level PWM Operation of an MMC Phase Leg with Reduced Module Capacitance

Mertens, Axel; Kucka, Jakub (New York, NY : Institute of Electrical and Electronics Engineers Inc., 2016)

The modular multilevel converter offers benefits for medium and high voltage power conversion due to indirect series connection of devices. The drawback is a large amount of capacitance that has to be installed in each ...
Quasi-two-level PWM operation of modular multilevel converters : implementation, analysis, and application to medium-voltage drives

Kucka, Jakub (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)

The low-frequency operation of modular multilevel converters, required by variable-speed drives, is generally challenging within the established operation modes. Especially when rated torque beginning from zero speed is ...
