Conference Proceeding
Tardelli, F., Costabeber, A., Jankovic, M., Clare, J., & Zanchetta, P. (2018). A Unidirectional Flying Chain-link Modular Multilevel Rectifier (FCL-MMR) with Reduced Energy Storage for Offshore Wind Integration. In 2018 IEEE Energy Conversion Congress and Exposition (ECCE) (2931-2937). https://doi.org/10.1109/ECCE.2018.8558413

© 2018 IEEE. In recent years, the Modular Multilevel Converter (MMC) has been widely recognised as the state-of-art for AC/DC conversion stages in the integration of offshore wind energy through HVDC links. The MMC guarantees high power quality, effi... Read More about A Unidirectional Flying Chain-link Modular Multilevel Rectifier (FCL-MMR) with Reduced Energy Storage for Offshore Wind Integration.

MMC front-end for klystron modulators: an augmented modulation scheme for arm balancing (2018)
Journal Article
Jankovic, M., Costabeber, A., Watson, A. J., Clare, J. C., & Aguglia, D. (2018). MMC front-end for klystron modulators: an augmented modulation scheme for arm balancing. IEEE Transactions on Plasma Science, 46(10), 3325-3333. https://doi.org/10.1109/TPS.2018.2837619

This paper discusses the control of a Modular Multilevel Converter (MMC) used as a grid-interface for the klystron modulators in the Compact Linear Collider (CLIC). The converter has a DC side load which takes short-duration power pulses, causing hig... Read More about MMC front-end for klystron modulators: an augmented modulation scheme for arm balancing.

Arm-Balancing Control and Experimental Validation of a Grid-Connected MMC With Pulsed DC Load (2017)
Journal Article
Jankovic, M., Costabeber, A., Watson, A. J., & Clare, J. C. (2017). Arm-Balancing Control and Experimental Validation of a Grid-Connected MMC With Pulsed DC Load. IEEE Transactions on Industrial Electronics, 64(12), 9180-9190. https://doi.org/10.1109/TIE.2017.2711516

This paper focuses on the operation of a grid connected Modular Multilevel Converter (MMC) supplying a pulsed DC load. The goal is to achieve minimum AC power fluctuation despite the high power fluctuation present on the DC side. The MMC has been sel...

Control of a modular multilevel converter with pulsed DC load (2016)
Conference Proceeding
Jankovic, M., Watson, A., Costabeber, A., & Clare, J. (2016). Control of a modular multilevel converter with pulsed DC load. In 2016 IEEE Energy Conversion Congress and Exposition (ECCE) (1-8). https://doi.org/10.1109/ECCE.2016.7854963

This paper focuses on a Modular Multilevel Converter grid interface for a klystron modulator system that behaves as a pulsed DC load. With such a load, and without mitigating control, the MMC suffers from cell capacitor voltage imbalance between the... Read More about Control of a modular multilevel converter with pulsed DC load.
