Digital Communications for the Control of Modular Multilevel Converters
19, Mar, 2019 11:30-12:30 (1 hour)
CISTER, Porto, Portugal

Invented in 2001, the Modular Multilevel Converter (MMC) marked a leap in the technology for converting and controlling the electrical energy in high voltage levels. The MMC has been widely studied, but the number of works that explore the use of digital communications in this application domain is limited.
The digital communication employed to implement an internal control network simplifies the converter assemblage and maintenance, among other benefits.
In this talk, we investigate several aspects of such systems. A highlight is a codesign strategy for the control and communication. It makes possible to operate Ethernet-based ring networks with quasi-optimum Minimum Cycle Time, allowing the control algorithms to execute at the necessary high rates.
Additionally, we investigate the internal delay of Ethernet nodes and propose hardware accelerators for implementation in Field Programmable Array technology that can minimize the latency during the reception of packets. After all, the contributions aim for reducing the difficulties implementing high-speed digital communications in Modular Multilevel Converters with a high number of cells, allowing at the same time all the benefits of such implementation without compromising the high performance of the system control.

Tomás P. Corrêa received the M.Sc and B.Sc in Electrical Engineering, both from the Federal University of Minas Gerais, Brazil, in 2008 and 2006, respectively. He is currently with University of Alcalá, Spain, where he pursues a PhD Degree. Between 2012 and 2015, he was with AVL List, Austria, working as a development engineer in the field of automotive test systems. Before he held different positions in industry, always working in R&D in the field of power electronics.
