Exxelia's Smart Magnetic: Breakthrough technology for more compact and powerful converters

The solutions provided by Exxelia's Smart Magnetic project are revolutionizing the field of electrical converters by offering unparalleled performance in terms of power density.

Smart Magnetics Exxelia

This advance makes it possible to design more compact, lighter converters. However, the advantages of this technology are not limited to these fundamental aspects. In this article, we will explore in detail the multiple functional, economic and environmental benefits offered by Exxelia's Smart Magnetic technology.

 

Functional advantages for increased reliability:

The Smart Magnetics project makes it possible in particular to optimize the Dual Active Bridge topology which requires the combination of a transformer and a choke.

The Dual Active Bridge converter is a technology that is becoming widespread because it allows bidirectional power transmission. This meets the challenges of electrical systems (recovery + supply of energy),

Integrating the Dual Active Bridge (DAB) transformer and choke into a single component has significant functional advantages. Unlike assembling two separate components, using an integrated component eliminates interconnections. The repeatability and reproducibility of the processes guarantee perfect control of the electrical characteristics, and ensure optimum performance of the converter. In addition, this consolidation reduces the number of components required, which improves the reliability of the final product.

 

Rationalization of the value chain for optimized production costs:

The Smart Magnetic project also contributes to improving the value chain through effective streamlining. By replacing two distinct components with a single component, the management of the components of the circuit is simplified. From the customer's point of view, there is only one product to supply, one product to integrate/assemble in the system. These simplifications result in high added value and increased competitiveness on the market.

 

Contribution to a more environmentally friendly industry:

By adopting Smart Magnetic solutions, the benefits go beyond simply improving energy efficiency. This innovation also reduces the consumption of raw materials by using less material in the Smart Magnetic component compared to standard formats requiring two separate components. As a result, this technology contributes to the preservation of natural resources. In addition, Smart Magnetic responds to the challenges posed by the electrification of vehicles, whether in air, land or sea transport, by promoting the deployment of solutions that are less dependent on fossil fuels.

 

Various applications:

The versatility of Smart Magnetic solutions makes it suitable for many applications. For example, it can be used as a bi-directional converter between batteries and circuits, for power applications or even in resonant converter topologies. It is also useful in applications requiring high current and in Multi-output flyback converters. This diverse range of applications testifies to the flexibility of the Smart Magnetic project.

Magnetic Components based on Adaptive CCM Technology Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating. Cost-effective Common-mode Chokes Qualified for Aerospace Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries.
