Dr. Peter Friedrichs from Infineon on the key applications for WBG power semicondutors
Dr. Peter Wallmeier, Senior Director R&D at Delta Energy Systems

The efficiency of switch-mode power supplies impacts energy use, from the consumption of the smart-phones in our pockets, to the photovoltaics powering our grids. Pushing that efficiency beyond today's 98% has an important role to play in fighting climate change - and energy costs. While the last 40 years have brought many advances in semiconductors, there is an increasing need for investment to improve the capabilities and properties of magnetic materials too.

Prof. Marco Jung talks to Dr. Peter Wallmeier, Senior Director R&D at Delta Energy Systems, about the issues in episode 4 of the"Sound On. Power On." podcast.

They also discuss the important opportunity presented by the combination of reactive loading, renewable power sources and storage in alleviating the voltage and frequency deviations that result from the increasing stresses on our modern, complex and interconnected power grids.

Dr. Peter Friedrichs from Infineon on the key applications for WBG power semicondutors
Dr. Ravi Venugopal, Managing Director, OPAL-RT Germany GmbH

Real-time simulation helps accelerate development and derisk early implementations in the race to transform to e-mobility and renewables. (Power) hardware-in-the-loop plays an important role. Among notable current needs is to simulate the new scenarios presented by grids with converter-driven energy sources, not least in testing for resonances, or black start conditions. For real-time simulation – particularly integrating power hardware – this presents new challenges to balance stability, accuracy, speed, and scale.

Prof. Marco Jung talks to Ravinder Venugopal, Managing Director at OPAL-RT Germany, about the issues and approaches (from parallel processing to solvers and FPGAs) in episode 3 of the "Sound On. Power On." podcast.

They also discuss the future, with digital twins harnessing live data to improve real-time simulations, with the support of AI.

Dr. Ravi Venugopal is the managing director of OPAL-RT Germany GmbH, the German subsidiary of OPAL-RT Technologies, a global market-leader in real-time simulation of power systems and power electronics.

He earned his doctorate in aerospace engineering from the University of Michigan, Ann Arbor, (USA) specializing in control systems. Furthermore he holds a master’s degrees in electrical engineering and aerospace engineering. He has over 25 years of experience in the field of real-time simulation across the energy, aerospace and automotive sectors. In the last ten years, he has worked closely with technical leaders on hardware-in-the-loop testing for power electronic systems with a focus on renewable energy integration and e-mobility. He is keenly interested in technology transition from academic and research institutions to industrial practice.

Dr. Peter Friedrichs from Infineon on the key applications for WBG power semiconductors

In the latest episode of "Sound on. Power on", host Prof. Marco Jung discusses the key applications of WBG power semiconductors with his guest Dr. Peter Friedrichs from Infineon and gives an outlook on the future. In addition to PV and electro mobility, uninterruptible power supplies are also mentioned and discussed as key innovation drivers. Both particularly emphasize the advantages of WBG in the context of energy efficiency and resource efficiency. In addition to SiC semiconductors, GaN semiconductors and their possible areas of application will be discussed. Furthermore, Peter and Marco consider the step into the high-power class, but only with corresponding packaging concept.

“Future trends in power electronics” with Frede Blaabjerg, Aalborg University
Prof. Frede Blaabjerg on the future of power electronics

In the first episode of “Sound On. Power On.” host Prof. Marco Jung and his guest Prof. Frede Blaabjerg from the Aalborg University in Denmark discuss trends in power electronics. Decentralized power generation through renewable energies, especially photovoltaic and wind energy, is on the rise worldwide. What are the next tasks for a success? Listen to Frede sharing his thoughts on the role of hydrogen as a future energy carrier and the main challenges correlating with this development. Marco and Frede provide answers on how to manage a successful energy transition considering a decrease in energy consumption, particularly in industrial applications. They talk about silicon carbide semiconductors in electric vehicles that promise higher efficiency, but also higher costs in comparison to Si-IGBTs. Where is the journey going?
