Explore space-ready power modules that combine transformers and inductors for efficient, lightweight satellite power solutions.

As space systems become more advanced and densely packed, engineers face growing pressure to deliver power solutions that combine efficiency, reliability, and compactness without compromising performance. Conventional magnetic components often struggle with high mass, volume, and interconnection complexity, making integration into space-grade power conditioning and distribution units (PCDUs) challenging. Achieving this requires solutions that withstand severe thermal cycling, mechanical stresses, and low-convection environments while maintaining near-optimal electrical performance.
Exxelia has introduced a custom Smart Integrated Magnetics solution specifically designed for DC-DC power conversion in high-reliability PCDUs. The assembly integrates the transformer and inductor of a Dual Active Bridge (DAB) into a single, low-profile package, reducing overall volume and mass while simplifying system interconnections.
The system is suitable for satellite power modules and other demanding space applications where efficiency, mechanical robustness, and thermal stability are critical. The design can be adapted to meet system-specific electrical, thermal, and mechanical requirements, allowing engineers to optimize integration within densely populated power electronics modules.
Key technology features include:
- 1–2 kW isolated DC-DC conversion at 100–200 kHz switching frequency
- High-efficiency operation up to 99%
- Compact planar form factor: 75 × 65 × 20 mm, ~250 g
- Fully customizable for electrical, thermal and mechanical constraints
Stéphane Peres, Exxelia spokesperson, says, “This Smart Integrated Magnetics solution demonstrates our ability to deliver highly efficient, compact and reliable magnetic assemblies for space and other high-reliability applications,” highlighting the role of integrated design in advancing power electronics under extreme environmental conditions.
