21. Modeling and Design of Modular MultilevelConverters for Grid Applications
Abstract : Grid-connected high-power converters are found in high-voltage direct current transmission (HVDC), static compensators (STATCOMs), and supplies for electric railways. Such power converters should have a high reliability, high efficiency, good harmonic performance, low cost, and a small footprint. READ MORE

22. Modeling of Modular Multilevel Converters for Stability Analysis
Abstract : Modular multilevel converters (MMCs) have recently become the state-of-the-art solution for various grid-connected applications, such as high-voltage direct current (HVDC) systems and flexible alternating current transmission systems (FACTS). Modularity, scalability, low power losses, and low harmonic distortion are the outstanding properties that make MMCs a key technology for a sustainable future. READ MORE

23. On conceptual development of modular products - Development of supporting tools for the modularisation process
Abstract : The research work detailed in this dissertation relates tothe development of modular products and product families.Historically, product variants have been developed more or lessindependently; but in order to stay competitive in todaysbusiness environment where globalisation and explosion ofvariety are some of the buzzwords, products should be developedas a product family.

24. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing
Abstract : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. READ MORE
