Abstract

This BB provides an in-depth overview of converter technologies for medium- and high-voltage applications, focusing on direct and indirect topologies, modulation strategies, and the specific technologies used in MVDC and HVDC systems. It covers both classic thyristor-based systems and modern IGBT-based voltage source converters, highlighting their architectures, operation principles, advantages, and challenges. Application examples include renewable energy integration, offshore wind connections, and long-distance power transmission.
