Séminaire sur les USB Type C Power Delivery

Avec STMicroelectronics et Würth Electronik

L’USB type C PD va révolutionner dans un futur proche le monde de l’alimentation à découpage de quelques watts de puissance jusqu’à 100W. Interopérabilité (via un protocole de communication et de reconnaissance robuste) négociation des contrats de puissance pour s’adapter au mieux au besoin de la charge sont les maitres mots de cette évolution dans la conception des alimentations.

Date: November 29, 2018
Language: Francais

Fee: Free of charge
No registration possible.

À travers 4 différents ateliers en parallèle, venez (re)découvrir cette liaison.

L’USB type C PD va révolutionner dans un futur proche le monde de l’alimentation à découpage de quelques watts de puissance jusqu’à 100W ! Interopérabilité (via un protocole de communication et de reconnaissance robuste) négociation des contrats de puissance pour s’adapter au mieux au besoin de la charge sont les maitres mots de cette évolution dans la conception des alimentations. Ce workshop en partenariat avec Würth Elektronik, STMicroelectronics et CST (Dassault Systèmes, SIMULIA) propose d’étudier en détail son fonctionnement au moyen de 4 sessions roulantes alliant théorie et pratique.

Quels sont les innovations et les nouveaux challenges à relever avec l’USB type C Power Delivery? Le standard permet la gestion de l’alimentation jusqu’à 100W en négociant 5V 1,5A jusqu’à 20V 5A ce qui nécessite d’appliquer des règles de sécurité en cas de défaillance éventuelle de la source, de plus le standard autorise le transfert de données jusqu’à 10Gb qui pourrait être de l’USB 3.1 mais aussi du display port ou même de l’HDMI. Les sessions 1 et 2 proposent de façon ludique d’approfondir l’USB type C PD ainsi qu’une de ses nombreuses applications qui est le « power sharing ».

La CEM est toujours un point délicat lors de la conception d’une alimentation à découpage, la fréquence de découpage ainsi que les éléments parasites des composants et du routage sont sources de bruit et ces niveaux de perturbation se doivent d’être réduits en deçà d’un minimum acceptable. Les sessions 3 et 4 proposent des méthodes d’investigation pour comprendre les sources des émissions conduites et les filtrer.


Session 1: Comprendre l’USB type C PD

Comment fonctionne le protocole et quels sont les points clés à prendre en compte lors de la conception.
Alain LAFUENTE, Würth Elektronik

Session 2: Exemple d’application: Power Sharing

Comment gérer le partage de puissance entre deux ports USB type A et 2 ports type C, que dit le protocole et comment l’implémenter?
Jean CAMIOLO, STMicroelectronics

Session 3: Simulation des émissions conduites d’un convertisseur DC/DC

L’utilisation d’un logiciel de simulation 3D des champs E et H permet d’appréhender les phénomènes de couplage et de propagations des bruits de façon intuitive pour anticiper en amont les problématiques de la CEM.

Session 4: Investigation CEM Filtrage des émissions conduites d’un convertisseur DC/DC

Quels sont les performances d’un filtre L, T, PI que l’on peut attendre pour filtrer les perturbations conduites générées par un abaisseur de tension.
Sylvain Le Bras, Würth Elektronik

Ces sessions durent 45 minutes, Les personnes participantes changeront d’atelier toutes les 45 minutes.
