Power Electronics
PowerCare
Saving megatons of greenhouse gas emissions in industry and mobility every year through intelligent power electronics with innovative gallium nitride semiconductors in motor control units?
In order to achieve independence from fossil fuels and switch to renewable energy sources, production and mobility must be extensively electrified. This increases the need for compact, energy-efficient and reliable power electronics. In the PowerCare project, innovative vertical gallium nitride power semiconductors and real-time-capable failure models are being developed and used in a motor drive. PowerCare is pursuing a new approach in the monitoring concept through a miniaturized motor controller with integrated AI failure prediction. The project thus lays the foundation for the next evolutionary stage of intelligent, sustainable power modules.

Electronic Energy Systems
Power Conversion
High-Efficiency Power Conversion for Smarter Energy Systems
We design and test advanced power converters for low to medium power for applications like drives and grid integration. Using cutting-edge technologies — GaN, SiC, planar transformers, and integrated multiport topologies —we deliver high efficiency and power density with minimal cost.
Featured at Our Booth:
The Smart Energy Router – a 40-kW configurable DC/DC converter that seamlessly integrates decentralized energy sources and storage.
- High availability: Active reliability through intelligent hardware-software fault tolerance, without heavy redundancy.
- Proven performance: Validated through Power Hardware-in-the-Loop (PHiL) testing under real-world conditions.
- Optimized design: Efficient, compact, and cost-effective solutions tailored to your application.
Discover the future of reliable, high-performance power conversion- only at our booth.
digital twin for power electronics
Enhanced performance and minimized down-time with our thermal digital twins:
Our thermal digital twin technology models the thermal behavior of power modules in real time. By monitoring a few key temperature points, we create an accurate virtual replica that estimates junction temperatures and tracks component health and aging.
Key Benefits:
- Real-Time ageing monitoring: Detect degradation early and avoid unexpected downtime.
- Smarter maintenance: Plan service based on accurate lifetime predictions.
- Extend PQ-power curves and overload capability by reducing design margins.
- Cut costs & size: Minimize overdesign with precise thermal data.
- Extend lifespan: Enable intelligent control strategies for longer module life.
Planar Transformers - Magnetic Components
As power electronics become more compact and efficient, magnetics play a critical role. Our custom planar transformers are engineered for high performance in space-constrained, high-power applications.
Featured at Our Booth:
Planar transformers delivering up to >30 kW/L and >200 kHz operation, designed for maximum efficiency and reliability.
Key Advantages:
- Ultra-High-Power density: Compact designs with power ratings up to >30 kW
- Precision performance: Optimized parasitics (leakage, capacitance, thermal resistance) for predictable behavior
- Low profile: Perfect for tight spaces without sacrificing capability
- Broad frequency range: Reliable performance across medium to high frequencies
- System-Level optimization: Leveraging in-house modeling and converter expertise for holistic, cost-effective designs

The Module Services working group offers comprehensive quality and reliability analyses as well as process optimization. We use our diverse analysis portfolio such as X-ray (2D, 3D, laminography), optical inspection, metallographic preparation and electrical tests (including active and passive aging and electrical load cycles up to 2000A). This portfolio is supplemented by methods for accelerated ageing such as temperature and climatic ageing, e.g. under electrical load.
Decades of experience in quality and reliability assessment as well as failure analysis of components, modules and systems of electronic assemblies in all areas of application, from control electronics to power electronics, provide the basis for targeted analysis. Complemented by our extensive manufacturing expertise in electronic systems, this provides the basis for qualified root cause analysis and the resulting process and production optimization for the manufacture of production-ready, cost-optimized and reliable electronics.
We are happy to support you with analytics and manufacturing know-how in the introduction of new technologies, the quality assessment of existing products and processes as well as the failure analysis and reliability assessment of your products.
