Fabriquer une Alimentation de Laboratoire Réglable 0-30V 5A (LM317 & 2N3055) Dans ce tutoriel, nous concevons une *alimentation stabilisée et variable de laboratoire* capable de délivrer une tension de *0 à 30V* avec un courant robuste de *5A*. Ce montage repose sur le célèbre régulateur *LM317*, associé à deux transistors de puissance *2N3055* montés en parallèle pour supporter des charges importantes sans surchauffe excessive. C'est l'outil indispensable pour tout électronicien souhaitant test
