“Power Electronics for Hydrogen Mass Production: State of the Art, Challenges and Outlook“ with Prof. Dr. Marco Jung of the Bonn-Rhein-Sieg University of Applied Science
Due to the future power grid integration of GW electrolysis parks, it is to be expected that these power electronics-coupled loads will be subject to stricter grid compliance guidelines and will will need to actively contribute to the stability of the power grid. This requires a further development of rectifier technology and its functionalities.
Hydrogen is an important energy carrier for the future energy supply of countries and industries. The necessary GW hydrogen production facilities must be integrated into existing systems. Electrolyzers must be supplied by DC power, which is supplied by rectifiers from the AC grid. Thus, power electronics has to fulfill the electrical grid compliance requirements and provide the correct current and voltage for the electrolysis process. These interfaces subject to changing requirements.
In episode 9 of the PCIM Podcast, Prof. Dr. Marco Jung provides an insightful overview of the current status, challenges and changing requirements of power electronics in hydrogen mass production, while also offering a glimpse into the future.

To meet the needs of E-Mobility developers and testers, today's high-power, power supplies and loads have to be programmable and able to simulate different scenarios, as well as to provide measurement data to not just test, but also validate and qualify batteries and fuel cells.
If we view this also in the context of time-to-market (and total cost of ownership), the right (bi-directional) power supply can play a role by being scalable not just in power, but also in interaction: that is, reusing tests and programming effort while transitioning from development to prototypes, and from prototypes to production.
At the end of the life cycle, after being used in E-Mobility, degraded batteries may have a second life in domestic or grid-coupled storage – but they need to be thoroughly qualified. Bi-directional power supplies can help, again, in achieving this – or in deep discharging batteries and fuel cells for recycling.
In episode 7 of the PCIM Podcast, Michael Himmels, Head of Product Management at EA Elektro-Automatik, talks about the role of power supplies, and how they continue to rise to emerging challenges.

„The role of high-power converters in efficient and stable smart grids“ with Prof. Dr.-Ing. Marco Liserre from Kiel University
The design and deployment of power converters are essential for the efficiency and smooth operation of modern smart grids.
In episode 6 of the PCIM Podcast, Prof. Dr.-Ing. Marco Liserre, Chair of Power Electronics, Kiel University, and the new host David Hegarty talk about the role of power converters in so many parts of the modern grid.
Widespread use means efficiency makes a huge difference. Modular topologies can be tweaked to push this efficiency and reduce the effects of passive components. Central to this achieving this potential is the use of digital twins, and power-hardware-in-the-loop to enable the synergetic design and prototyping of effective modulation and control – which apart from boosting efficiencies can also improve the handling of faults at the component and system levels.
While this has long been obvious for wind and photovoltaic generation, the spread of charging stations has also created new infrastructure challenges, where smart power converters can play an essential role in grid-forming and -management, contributing to the stability of the whole system.

„Future Challenges for Magnetics in Power Electronics“ with Prof. Dr.-Ing. habil. Peter Zacharias, University of Kassel
Magnetic materials have a special role to play in opening the bottlenecks in achieving higher power densities, higher frequencies, and smaller and lighter components for electrical power supply systems.
This involves exploring new materials, new ways of combining materials, and new form factors. The results can stretch the specifications - such as frequencies up to the 10s of MHz - and reduce the challenges of cooling requirements, and skin and proximity effects, as well as the handling of resonant frequencies and the variety of fluxes in multifrequency components.
