Abstract
BLOC DE COMMANDE VERTICALE, DANS LEQUEL LA TENSION DE SORTIE D'UN GENERATEUR DE DENTS DE SCIE, QU'UN ETAGE DE SYNCHRONISATION BRANCHE A CHAQUE PASSAGE PAR ZERO DE LA TENSION ALTERNATIVE DE COMMANDE SYNCHRONE AVEC LE RESEAU, EST COMPAREE POUR CHAQUE PHASE A UNE TENSION DE COMMANDE PAR UN COMMUTATEUR DELIVRANT UN SIGNAL A UN CONFORMATEUR D'IMPULSIONS D'ALLUMAGE LORS DE L'EGALITE DES VALEURS ABSOLUES DES DEUX TENSIONS. LES INTEGRATEURS DES GENERATEURS DE DENTS DE SCIE 2 CONSTITUENT CHACUN UN SYSTEME REGLE, INSERE DANS UNE BOUCLE DE REGULATION 5, 6, 7, 8, DE FACON QU'UNE GRANDEUR PILOTE COMMUNE ETANT PREDETERMINEE, LES INTEGRATEURS SE CHARGENT A UNE MEME VALEUR DE CRETE PENDANT LE TEMPS FIXE PAR DEUX PASSAGES SUCCESSIFS PAR ZERO DE LA TENSION ALTERNATIVE DE COMMANDE U SYNCHRONE AVEC LE RESEAU.
