Abstract

This presentation will consider the implications of the current trend towards the electrification of many modes of transport.  The talk will focus on the technological challenges for power electronics and motor drive engineers.  Examples used in the talk will include many of the technologies that have been developed for our race and award winning electric superbike, a great example of a high performance vehicle with a well-defined use case resulting in an optimised electrical system. Using this use case it is possible to begin to understand the requirements and technology advances needed for future electric vehicles including the challenges still to be addressed.

He has published a major theoretical reference book on this subject, together with over 250 refereed journal and conference articles (11000+ citations). He is a Fellow of the IEEE, reviews papers for all major IEEE transactions in his area, and has been an active member of the Industrial Applications, Power Electronics Societies of the IEEE for over 25 years.

Abstract

For most of the 20th century, electrical energy has been generated by high power rotating generators that supply customers through a network of high voltage transmission lines and lower voltage distribution feeders. However, as the world moves inexorably towards Distributed Generation of renewable electrical energy, present day power system technologies are finding it harder and harder to meet the requirements of this new paradigm. Their fundamental limitations are clear – conventional generation assumes the availability of large scale stored energy for a small number of large generators, and energy is always assumed to flow unidirectionally from generators to consumers. Neither construct matches well with Smart Grid concepts, and alternative operating approaches are clearly required!

One foundational technology of Distributed Generation is the Power Electronic Converter, which can rapidly and flexibly control electrical energy almost instantaneously on a moment by moment basis. Since the 1950’s, PE converters have become mainstream technology for industry, accurately controlling rotating machines, precisely processing energy with minimum energy wastage, and supporting a myriad of other applications. More recently, as their power handling capacity continues to increase, they are becoming very attractive for distributed generation systems where they can manipulate electrical energy in ways that simply cannot be done using rotating machines. The challenge at present is to decide exactly what we want to do with this capability.

This presentation will explore why power electronic converters are so flexible and attractive for Distributed Generation systems. It will firstly reflect on how the fundamental properties of these systems make them so versatile, and then will proceed to show how these properties particularly suit Distributed Generation needs and requirements. Finally, the current challenges of large scale usage of power electronic converters in electrical grid systems will be considered, looking at both technical challenges that are still to be overcome, and the operational control challenges that are still in the early stages of development.

Abstract

Electric vehicles (EVs) are gaining global acceptance as the means of future transport for sustainable living and as an alternative energy storage to stabilize the electricity network through the vehicle-to-grid (V2G) concept.  For V2G applications, EVs essentially require a bi-directional power interface with the electricity network (grid) to allow for both storing (charging) and retrieval (discharging) of energy.  This can be achieved by both wired and wireless means, but the latter, based primarily on Inductive Power Transfer (IPT) technology, is becoming more popular, being convenient, safe, and ideal for both stationary and dynamic (while on the move) charging of EVs.  This seminar presents trends and the latest advances in wireless grid integration of EVs, focusing particularly on the bi-directional wireless power transfer (BD-WPT) technology developed for V2G applications.  The latest advances in relation to both stationary and dynamic wireless charging are discussed, highlighting the challenges and solutions proposed to mitigate the problems associated with pad-misalignment, synchronization and pulse charging.

Abstract

This talk will start with a brief historical review of “near-field magnetic” wireless power transfer dating back from Nicolas Tesla’s work a century ago. It will highlight how magnetic resonance (a technique used by Tesla and many others up to the 1990s) is not a recent invention. It will also explain why WPT became feasible again since 1980s with some highlights of landmark examples. The final part of the talk will focus on the latest development of international WPT standards and future developments for wireless charging of “portable” electronics.

Abstract

The energy paradigms in many countries (e.g., Germany and Denmark) have experienced a significant change from fossil-based resources to clean renewables (e.g., wind turbines and photovoltaics) in the past few decades. The scenario of highly penetrated renewables is going to be further enhanced– Denmark expects to be 100 percent fossil-free by 2050 – and maybe even before.

Consequently, it is required that the production, distribution and use of the energy should be as technologically efficient as possible and incentives to save energy at the end-user should also be strengthened. In order to realize the transition smoothly and effectively, energy conversion systems, currently based on power electronics technology, will again play an essential role in this energy paradigm shift. Using highly efficient power electronics in power generation, power transmission/distribution and end-user application, together with advanced control solutions, can pave the way for renewable energies. In light of this, some of the most emerging renewable energies — , e.g., wind energy and photovoltaic, which by means of power electronics are changing character as a major part in the electricity generation —, are explored in this presentation. Issues like technology development, implementation, power converter technologies, control of the systems, and synchronization are addressed. Special focuses are paid on the future trends in power electronics for those systems like how to lower the cost of energy and to use emerging power devices and enable better reliability tool for system assessment.

Abstract

Storage chokes and transformers are key components for high-efficiency, clocked voltage transformers. However, young engineers often face contradictions and uncertainties in this area. These results from different factors:

Lack of basics: Without solid basic knowledge myths persists.
Lack of standards or imprecise information from the manufacturer cause further confusion.
But what are the parameters that need to be specified?

What about inductors and their materials in the new transistor technology GaN / SiC?
Are the materials really so bad? How can you optimize the design?

Alexander Gerfer addresses the question in his keynote speech and presents his point of view and recommendation.
