Joint Webinar with IEEE Power Electronics Society
Presenter: Dr. Haoyu Wang, Shanghai Tech University
Date: Wednesday, July 8, 2020, 8:00am New York Time
Abstract: The transportation sector consumes approximately 28% of the total energy consumption. The most prominent sustainable solution to profoundly reduce both oil consumption and greenhouse gas emissions lies in grid-enabled electric vehicles (EVs). These vehicles are propelled either partially or fully by electricity through energy storage systems such as electrochemical batteries, which need to be charged from the grid. One of the most important realities that will facilitate the adoption of grid-enabled plug-in EVs (PEVs) is the method by which these vehicles will be charged. Currently, conductive charging is the dominant charging technology in commercially available PEVs.
In this webinar, I will give an extensive overview of the conductive charging technology of PEV from the perspective of a power electronics professional. The background review covers the charging power levels, PEV charger architectures, charging profiles of Lithium-ion batteries, as well as the challenges and opportunities. Followed by is a comprehensive review of state-of-the-art emerging solutions to those technological challenges. The advanced topics include innovative circuit topologies, advanced control strategies, integrated architectures wide bandgap devices, and boosted power density with high switching frequency. Furthermore, I will give an introduction to our recent related research works. Finally, the webinar concludes with an outlook on future technology trends.
New Technologies and Global Energy Efficiency Regulation Developments for Electric Motors and Drives
Sponsored by the IEEE Industry Applications Society
Presenter: Anibal T. De Almeida, University of Coimbra: Institute for Systems and Robotics
Date: Wednesday, January 15, 2020, 11:00am EST
Abstract: Energy-efficient motor systems have a huge electricity savings potential, presenting a cost-effective option for reducing GHG emissions. The electric motor market has witnessed a major change in the last decade in several aspects: in technology leading to the availability higher efficiency models, in content with energy-efficiency policies, the need for more sustainable industrial production and in its economy due to increasing electricity prices, all aspects contributing to push the market towards more energy-efficient electric motors.
Additionally, the growing market penetration of Variable Speed Drives (VSD), introducing large energy savings in systems with variable loads, was accompanied by a growing concern over their operating efficiency in full and especially in part-load, as well as in standby mode.
In Europe, recent developments in motors and drives efficiency regulation under the umbrella of the Ecodesign Directive have highlighted the significant savings that can still be achieved in the field by raising the minimum efficiency performance standards (MEPS) for motors and introducing new standards for Variable Speed Drives (VSDs).
This webinar presents an overview of minimum efficiency standards around the World, analyses the relationship between the introduction of new regulations and the development of new technologies, as well as the potential impact in terms of electricity savings and corresponding reduction in GHG emissions.
The increasing number of countries implementing MEPS for motors, together with the growing awareness within governments and industry towards the importance of energy-efficiency and its multiple benefits, has led to the market introduction of new technologies with great improvements in the energy efficiency of motors, which now reach levels well above the IE3 level, known as Super- and Ultra-Premium Efficiency Motors (IE4 and IE5, respectively), and of high-efficiency VSDs.
