The developments of power converters and systems are driven by three mega trends:
- Intelligent Power Electronics (Industry 4.0, Artificial Intelligent Condition monitoring)
- Electrification of transportation
Industry 4.0 combines the information technology, that has been strongly developed during the last 20 years, with industrial electronics building the bridge from only information to hardware and products. This includes the topics internet of things, big data and automatization but also energy efficiency, reliability and the integration of renewables.
Electrification of transportation is not limited to electrical vehicles but covers also the charging infrastructure, autonomous cars and electrification of ships, airplanes and off-road vehicles.
The enablers for these mega trends are the new materials in power electronics, that allow much more efficient energy transformation and thereby significant more compact designs allowing power electronics in applications that have not been possible before due to space losses and costs.
Research scope
Our drivers are the new opportunities that arise from the rapid developments in the fields of digitalization and new power semiconductors. These two mega trends provide many possibilities for new applications and solutions. We strive for covering the whole chain from components via systems towards the application and solution. On component level we are developing, analyzing components always with the focus on reliability and life-time prediction. On system level we aspire to utilizing the components in the most efficient way by developing new topologies, applying new and advance control strategies that are enabled by the rapid developments in the field of calculation power. On application level we combine information technologies with hardware to contribute in the development of internet of things. All this is supported by utilizing the new measures of simulation.
