Ke300g

La principale difficulté des convertisseurs antidétonation est la dissipation de chaleur.Étant donné que tous les éléments des Transducteurs antidétonateurs sont installés dans la Chambre, l'air ne peut pas circuler et le problème de la dissipation de chaleur est devenu critique.La principale source de diffusion des transformateurs de la série ke300g antidétonation est la fréquence de commutation commandée par IGBT.La société a mis au point son propre circuit de base IGBT, a réussi à résoudre les problèmes de dissipation de chaleur.
