Absorbeur de pointes FETtec
Absorbeur de pointes FETtec L'absorbeur de pics FETtec utilise des diodes TVS bien choisies pour éviter que les composants connectés subissent d'énormes pics de tension. L'absorbeur de pics est destiné à être utilisé en complément d'un condensateur électrolytique. Le condensateur peut être monté directement sur le dessus de la carte.
Il veillera à ce que la tension ne dépasse pas un niveau spécifique. Cela signifie qu'il absorbe de l'énergie une fois que le niveau de tension spécifique est atteint.
Sur les systèmes d'alimentation électrique utilisant des moteurs sans balais, des ESC et des batteries LiPo, les pics de courant et de tension élevés sont courants. Le moyen le plus connu pour les maintenir dans des zones où ils n'endommagent pas les éléments connectés à la batterie est l'utilisation de condensateurs. Les condensateurs amortissent tout mouvement de tension. Ils stockent l'énergie si la tension augmente et la restituent lorsque la tension chute. Mais dans certains cas, il existe des pics de tension très courts mais élevés lorsque les condensateurs sont trop lents. Ces pics sont généralement très courts et apparaissent dans la zone de quelques nano-microsecondes, mais peuvent facilement être deux ou trois fois supérieurs à la tension normale de la batterie.
La plupart des appareils électroniques grand public peuvent résister à de nombreux pics de tension, même s'ils dépassent leur tension nominale normale. Cependant, si le pic est trop fort ou s'il se produit sur une période plus longue, les régulateurs de tension, les condensateurs et les FET peuvent être endommagés et tomber en panne. L'absorbeur de pics absorbera l'énergie de ces pics avant qu'ils n'atteignent des zones où les appareils pourraient être endommagés.
L'absorbeur de pics de tension absorbe les pics de tension afin que les tensions dommageables ne soient pas atteintes du tout
