Abstract

Prezenta inventie se refera la un procedeu si un dispozitiv de comanda a comutarii polaritatii convertizoarelor bidirectionale de redresare comandata mono si polifazata. Functionarea în regim de redresare, de o polaritate sau alta, se realizeaza de catre un releu static cu limitare capacitiva, comandat discriminat, pe câte o singura alternanta de catre un bloc de comutare, permitându-se astfel functionarea unuia din cele doua tiristoare în antiparalel. Dispozitivul de comanda se poate aplica la convertizoarele bidirectionale de redresare cu tiristoare monofazate în punte sau cu punct median si polifazate în punte sau stea.BACKGROUND OF THE INVENTION The present invention relates to a bi-directional polarity control switching method and control device controlled mono and polyphase. The polarization or polarization operation is accomplished by a static relay with capacitive limitation, discriminatedly controlled, on a single alternation by a switching block, thus allowing the operation of one of the two thyristors in the antiparallel . The control device can be applied to bidirectional single-phase thrust converters with or with a mid-point and polyphase in a bridge or star.
