Webinar series: Impact of High Frequency Switching on Electrical Machines

Date:  April 14, 2021

Time: 12:30 pm – 1:45 pm
Free to attend – register for this webinar!

Please continue to check back in the coming weeks as this event is part of a series.  All information and registration for the three webinars can be found on https://webinars.on24.com/theIET/HighFrequency?partnerref=Committee

 

Jointly organised by the IET PEMD Technical Network and UK Centre for Power Electronics.

 

The fast switching speed, higher switching frequency of wide-bandgap (SiC, GaN)  power devices have brought in clear opportunities in achieving high-density, higher-efficiency, higher-frequency and highly-integrated motor drives. However, the high frequency switching can also negatively impact electric machines. For example, high dv/dt and high switching frequency can cause increased level of over-voltage at motor terminals and neutral, insulation and bearing degradation and electro-magnetic interference. Under the high dv/dt of SiC drives, motor terminals will see clear over-voltage with much shorter cables than that under Si IGBT motor drives and the voltage stress will mostly drop on the first several turns of the motor windings.

 

In this webinar series, the impact of high-frequency switching on electric machines will be investigated in terms of high-frequency modelling, high-speed measurement, insulation partial discharge and reliability analysis together with proposed mitigation solutions and experimental validation. An introduction and update on the Future Electrical Machines Manufacturing Hub will also be provided.

 

This webinar series is suitable for both industrial and academic audience and will provide insight of the opportunities, challenges and solutions of the adoption of wide-bandgap motor drives, in comparison to existing Si based drive systems.

 

In Part 1, we’ll be joined by two excellent speakers:

 

Xibo Yuan, University of Bristol – Opportunities, challenges and potential solutions in fast-switching wide-bandgap (WBG) motor drives

 

Davide Barater, University of Modena and Reggio Emilia, Italy – WBG motor drives with very high voltage gradients: modelling and design solutions.

Professor Martin Kuball named as Royal Academy of Engineering Chair in Emerging Technologies

Professor Martin Kuball, Director of the Centre for Device Thermography and Reliability (CDTR) in the HH Wills Physics Laboratory, has been awarded the Royal Academy of Engineering Chair in Emerging Technologies.

Professor Martin Kuball

Professor Kuball was involved in the Tranche 1 ”Devices” theme of the Centre and is one of eight engineering academics across the UK to receive support from the Royal Academy of Engineering’s largest research funding scheme—the Chairs in Emerging Technologies – which has allocated a total of £22 million to support these innovative researchers and global leaders in their fields whose projects made it through the rigorous selection process in the face of stiff competition.

For his project as Chair, ‘Ultra-wide bandgap emerging power electronics for a low-carbon economy’, Professor Kuball aims to develop a new class of semiconductor power electronic devices using ultra-wide bandgap materials such as gallium oxide, boron nitride and aluminium nitride. Thanks to the outstanding properties of these materials, the new devices will be compact, highly versatile and energy efficient. This new generation of power electronics is the key to transforming a wide range of real-life applications, from data centres and motor drives to electric vehicle chargers to smart grids, all contributing to the realisation of a greener society.

Almost all low-carbon technology presently relies on Silicon (Si) based power electronic devices. However, some is starting to be replaced with wide bandgap semiconductors based on Gallium Nitride (GaN) and Silicon Carbide (SiC) to enable our daily lives. While these devices are serving us well, the unequivocal need to accelerate the reduction of our carbon footprint and to reduce the ongoing climate changes demonstrates the clear urgency to do much more, which this new class of materials and devices will enable.

Professor William Drury elected Fellow of the Royal Academy of Engineering

Royal Academy of Engineering Visiting Professor of Innovation William Drury joins the Royal Academy of Engineering as a Fellow.

Professor William Drury

Professor Drury joins 53 leading engineers from the UK and around the world who have been newly elected Fellows of the Royal Academy of Engineering in recognition of their outstanding and continuing contributions to the profession.

All the new Fellows were formally admitted to Fellowship at the Academy’s online AGM on Tuesday 22 September, and they will add their expertise to a Fellowship of almost 1,600 eminent engineers from both industry and academia.

Congratulations to Professor Bill Drury for being elected Fellow of the Royal Academy of Engineering. Bill has made great contribution to the power electronics centre from the very beginning and provided invaluable steering to the Centre’s operation and direction.

Sir Jim McDonald FREng FRSE, President of the Royal Academy of Engineering, said: “As the UK’s National Academy for engineering and technology, we bring together an unrivalled community of leading business people and industrialists, entrepreneurs, innovators and academics from every part of engineering and technology. The new Fellows who join us today are among the most talented and successful engineers working in the field today, leaders in areas from transport and our essential data infrastructure to lifesaving developments in medical research.”

Professor Drury became a Visiting Professor at the University of Manchester in 1997, and is a Royal Academy of Engineering Visiting Professor of Innovation at Bristol and a Visiting Professor at Newcastle University.

Professor Drury has worked for over 40 years in the engineering industry and is a member of the Institution of Engineering and Technology Academic Accreditation Committee. He has chaired several International Conferences in the field of power electronics, machines and drives and has more than 70 publications.
