Title (EN) MULTI-PULSE CONSTANT VOLTAGE TRANSFORMER FOR A VARIABLE SPEED DRIVE IN CHILLER APPLICATIONS
(FR) TRANSFORMATEUR DE TENSION CONSTANTE À IMPULSIONS MULTIPLES POUR UN VARIATEUR DE VITESSE DANS DES APPLICATIONS DE RÉFRIGÉRATION
Abstract:
(EN) A multi-pulse transformer with multiple taps provides a constant magnitude voltage output to a variable speed chiller's compressor motor over a range of input voltages. The 3-phase transformer includes primary windings and a plurality of secondary windings. The secondary windings are electromagnetically coupled with the associated primary winding. The primary windings include taps for receiving multiple input AC voltages and the secondary windings have a single output terminal for supplying a predetermined output voltage which, after rectification produces a DC multi-pulse waveform for powering a DC link of a variable speed drive. Alternatively the 3-phase transformer includes multiple taps on the secondary windings. Each of the primary windings has a terminal for receiving an input AC voltage. The taps of the secondary windings provide an output voltage that is converted to a multi-pulse waveform for powering a DC link of a variable speed drive.
(FR) L'invention concerne un transformateur à impulsions multiples comportant de multiples prises et qui fournit une tension de sortie à amplitude constante à un moteur de compresseur du refroidisseur à vitesse variable sur une plage de tensions d'entrée. Le transformateur triphasé comprend des enroulements primaires et une pluralité d'enroulements secondaires. Les enroulements secondaires sont électromagnétiquement couplés à l'enroulement primaire associé. Les enroulements primaires comportent des prises destinées à recevoir de multiples tensions alternatives d'entrée et les enroulements secondaires comportent une seule borne de sortie destinée à fournir une tension de sortie prédéterminée qui, après redressement, produit une forme d'onde à impulsions multiples de courant continu pour alimenter une liaison à courant continu d'un variateur de vitesse. En variante, le transformateur triphasé comprend de multiples prises sur les enroulements secondaires. Les enroulements primaires comprennent chacun une borne destinée à recevoir une tension alternative d'entrée. Les prises des enroulements secondaires fournissent une tension de sortie qui est convertie en une forme d'onde à impulsions multiples pour alimenter une liaison à courant continu d'un variateur de vitesse.
