Lieu d'origine: CHINE
Positionnement du produit :
La barre omnibus du module de puissance de l'onduleur HTD est le composant conducteur et structurel principal du système de commande électrique, responsable de la transmission à courant élevé entre les condensateurs du lien CC et les modules de puissance IGBT (ou carbure de silicium). Grâce à une conception d'intégration laminée et à des processus de moulage par injection intégrés, il atteint une densité de courant élevée, une faible inductance parasite et une excellente compatibilité électromagnétique, garantissant un fonctionnement stable et efficace du contrôleur de moteur dans un espace limité.
Paramètres de performance clés du moulage par insertion :
