Power converters and systems

The advancements in power converters and systems are being shaped by three major trends:

  • Intelligent Power Electronics (Industry 4.0, Artificial Intelligent Condition monitoring)
  • Electrification of transportation
  • Energy efficiency

Industry 4.0 integrates information technology, which has seen strong development over the last 20 years, with industrial electronics, bridging the gap from information to hardware and products. This encompasses topics such as the internet of things, big data, automation, energy efficiency, reliability, and the integration of renewables.

The electrification of transportation extends beyond electric vehicles to encompass the charging infrastructure, autonomous cars, and the electrification of ships, airplanes, and off-road vehicles.

New materials in power electronics enable much more efficient energy transformation, leading to significantly more compact designs that allow for power electronics in applications where space losses and costs were previously prohibitive.

Research scope

Our driving force is the new opportunities that arise from rapid developments in the fields of digitalization and new power semiconductors. These two mega-trends provide numerous possibilities for new applications and solutions. We aim to cover the entire chain from components to systems and towards applications and solutions. At the component level, we focus on developing and analyzing components with a strong emphasis on reliability and predicting their lifetime. On the system level, we strive to efficiently utilize the components by developing new topologies and applying advanced control strategies enabled by the rapid developments in computation power. At the application level, we integrate information technologies with hardware to contribute to the development of the Internet of Things. All of this is supported by utilizing new simulation methods.
