H-bridge

The electrical drive device is driven in two directions with different loads per drive direction, especially both directions of rotation, by a circuit with at least four bridge switch elements (S1-S4). The individual switch elements of the bridge circuit are configured in respect of their power dime...

More Information
Summary:The electrical drive device is driven in two directions with different loads per drive direction, especially both directions of rotation, by a circuit with at least four bridge switch elements (S1-S4). The individual switch elements of the bridge circuit are configured in respect of their power dimensions in the sense of a full bridge according to their respective maximum loadings Independent claims are also included for the following: (a) a drive device with mechanical switches (b) and a drive device with electronic switches. Der Kostenaufwand für eine über eine Vollbrücken-Schaltung mit zumindest vier Schaltelementen (S1-S4) je Drehrichtung (nl bzw. n2) mit unterschiedlicher Belastung (IL,1 bzw. IL,2) betreibbare elektrische Antriebsvorrichtung (M), insbesondere motorischer Kraftfahrzeug-Fensterheber oder Kraftfahrzeug-Gurtroller, kann dadurch gemindert werden, dass die Schaltelemente (S1-S4) im Sinne einer asymmetrischen Vollbrücke jeweils individuell entsprechend ihrer unterschiedlichen Maximalbelastung dimensioniert sind.
