Title (EN) CYCLOCONVERTERS AND METHODS OF OPERATING THEM
(FR) CYCLO-CONVERTISSEURS ET PROCEDE D'ACTIONNEMENT DE CEUX-CI
Abstract: front page image
(EN)A cycloconverter includes a microprocessor which governs the order of firing of the controlled rectifiers of the cycloconverter in order to produce an output of selected form or frequency. The order of firing may be different from that of the sequence of the supply phases and the microprocessor may change from one programme to another and change the order of firing in order to adjust the output frequency or voltage in order, for example, to control the speed of any suitable alternating current machine such as a squirrel-cage induction motor.
(FR)Cyclo-convertisseurs comprenant un microprocesseur regissant l'ordre d'allumage des redresseurs commandes du cyclo-convertisseur de facon a produire une sortie d'une forme ou frequence selectionnee. L'ordre d'allumage peut etre different de celui de la sequence des phases de l'alimentation et le microprocesseur peut passer d'un programme a un autre et changer l'ordre d'allumage de facon a ajuster la frequence ou la tension de sortie pour, par exemple, commander la vitesse de toute machine adaptee a courant alternatif tel qu'un moteur a induction a cage d'ecureuil.
