Abstract – Mega trends shape the car concept of tomorrow: E-Mobility, Automated Driving, Connectivity and Security. Today, around 80% of all innovation in automotive is related to innovation in semiconductors. In this paper we will take a look at the trends of E-Mobility and Automated Driving. First, we will look at the society needs and legislation, driving those trends. After that we will analyze individual system requirements of electric and hybrid vehicles, as well as automated cars of Levels 3 and beyond, driving, for example, the need for the fail operational systems. In later stage, we will showcase the semiconductor solutions for those requirements, taking a deeper look especially in semiconductor solutions for power electronics and motor drives. Some of the presented technologies will include: wide bang gap semiconductors vs. classical Si-based solutions, advanced packaging and chip embedding, novel current sensors, integrated end of shaft motor position sensors vs. resolver based sensing and automotive microcontrollers of the next generation.

Since 2015, he has been with ABB Switzerland Ltd, Turgi, Switzerland, where he is currently a Senior R&D Engineer working on the product development of medium voltage high power multilevel static frequency converters for grid-connected applications.
He is the author/co-author of several journal articles, conference papers and patent applications.

Abstract – Several grid applications, such as railway electrification and converter-fed synchronous machines for variable speed pumped hydro storage plants, require more and more efficient and robust static frequency converters. Direct AC/AC modular multilevel converters constitute very powerful solutions, however, more challenges arise compared to their use in HVDC systems. This keynote addresses topics such as the choice of cell semiconductor device, failure handling, modulation and harmonic performance as well as power losses. Additional aspects such as fulfilling grid code requirements from a closed-loop control perspective as well as global system design optimization are discussed.

Abstract – The large-scale integration of renewable electricity generation poses both structural, economic and management challenges. Among the major challenges, one can note the grid integration and the routing of this energy from the production units to the consumption poles. Major issues have to be faced like insufficient transmission capability, inertia reduction, stability margins mitigation. The HVDC is not a new idea but it can provide some interesting answers to these challenges. The keynote will list the locks and how they can be addressed by the HVDC grid. Finally, the underlying scientific issues will be discussed.

Abstract – The requirements for highly dynamic power hardware-in-the-loop (PHiL) converter systems depending on their use cases are explained. This includes the application specific requirements for the emulation converters, which must have either a voltage source (e.g. ideal grid) or a current source behavior (e.g. electrical machines, long power lines and cables). Furthermore the dynamic system requirements are discussed, which are significantly defined by the dynamics of the test scenarios to be emulated. Based on this, different emulation converter topologies are presented and compared.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Abstract – Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
