Smart Magnetic d'Exxelia : La technologie de rupture pour des convertisseurs plus compacts et plus puissants

Les solutions apportées par le projet Smart Magnetic d’ Exxelia révolutionnent le domaine des convertisseurs électriques en offrant des performances inégalées en termes de densité de puissance.


Smart Magnetics Exxelia

Cette avancée permet de concevoir des convertisseurs plus compacts, plus légers. Cependant, les avantages de cette technologie ne se limitent pas à ces aspects fondamentaux. Dans cet article, nous explorerons en détail les multiples bénéfices fonctionnels, économiques et environnementaux offerts par la technologie Smart Magnetic d’Exxelia.

 

Avantages fonctionnels pour une fiabilité accrue:

Le projet Smart Magnetics permet en particulier d’optimiser la topologie Dual Active Bridge qui nécessite l’association d’un transformateur et d’une self.

Le convertisseur Dual Active Bridge, est une technologie qui se généralise car il permet la transmission de puissance de manière bidirectionnelle. Cela répond aux enjeux des systèmes électriques (récupération + fourniture d’énergie),

L'intégration du transformateur Dual Active Bridge (DAB) et de la self en un seul composant présente des avantages fonctionnels significatifs. Contrairement à l'assemblage de deux composants distincts, l'utilisation d'un composant intégré élimine les interconnexions. La répétabilité et reproductibilité des procédés garantissent une parfaite maîtrise des caractéristiques électriques, et assure des performances optimales du convertisseur. De plus, cette consolidation permet de réduire le nombre de composants nécessaires, ce qui améliore la fiabilité du produit final.

 

Rationalisation de la chaîne de valeur pour des coûts de production optimisés:

Le projet Smart Magnetic contribue également à l'amélioration de la chaîne de valeur grâce à une rationalisation efficace. En remplaçant deux composants distincts par un composant unique, la gestion des composants du circuit se trouve simplifiée. Du point de vue client, il n’y a qu’un produit à approvisionner, un produit à intégrer/monter dans le système. Ces simplifications se traduisent par une forte valeur ajoutée et une compétitivité accrue sur le marché.

 

Contribution à une industrie plus respectueuse de l'environnement :

En adoptant les solutions Smart Magnetic, les avantages vont au-delà de la simple amélioration de l'efficacité énergétique. Cette innovation permet également de réduire la consommation de matières premières en utilisant moins de matériaux dans le composant Smart Magnetic par rapport aux formats standards nécessitant deux composants distincts. De ce fait, cette technologie contribue à la préservation des ressources naturelles. De plus, Smart Magnetic répond aux défis posés par l'électrification des véhicules, qu'il s'agisse du transport aérien, terrestre ou maritime, en favorisant le déploiement de solutions moins dépendantes des énergies fossiles.

 

Des applications variées :

La polyvalence des solutions Smart Magnetic la rend adaptée à de nombreuses applications. Par exemple, elle peut être utilisée comme convertisseur bidirectionnel entre les batteries et les circuits, pour les applications de puissance ou encore dans des topologies de convertisseur résonant. Elle trouve également son utilité dans les applications nécessitant un courant élevé et dans les convertisseurs Flyback Multisorties. Cette gamme d'applications diversifiée témoigne de la flexibilité du projet Smart Magnetic.

2023 Revolutionary Exxelia MML™ Ultra-High Energy Density Film Capacitors

Discover the power of MML™ technology The best performing film capacitors on the market with the highest energy density ever! Exxelia&#39;s revolutionary MML™ ultra-high energy density Film Capacitors are a game changer in the industry due to their unparalleled energy density of 400 J/dm3. This allows for a significant reduction in size and weight in comparison to traditional Polypropylene or Polyester dielectrics, as well as an increased operating temperature of up to 140°C and protection against transient voltage. Not only do MML™ capacitors offer a large flexibility in design, allowing for low profile configurations, but they have also been tested in actual cases for controls and DC-Links functions in aircraft applications and have shown a reduction in size and weight of about 50% compared to other film technologies.   Furthermore, when compared to MLCCs, MML™ capacitors have demonstrated a reduction in weight of between 70% to 90%, with no capacitance derating with voltage applied and a low drift of less than 5% across the temperature range. Applications that previously required clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with the added reliability that film dielectric offers. The exceptional properties of Exxelia&#39;s new MML™ capacitors make them suitable for a wide range of applications including power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any other applications that require confined electronics. Samples are available upon request.     Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable   Get your white paper around our MML Film Capacitor Download our white paper now on our innovative Miniature Micro-Layer™ (MML™) technology, which offers the highest capacitance per volume for film capacitors available on the market, by filling out the form below.   Chargement&hellip;
