Abstract:
(EN) The invention relates to a method for operating an inverter (130) for a drive system (100). The inverter (130) is designed to electrically couple a direct-current source (110) to a drive device (120) of the drive system (100). The method has a step of reading an operating point signal (150) which represents at least one electric inverter (130) output signal requested by the drive device (120). The method also has a step of determining a switch frequency for the inverter (130) using the operating point signal (150) and a step of providing a frequency signal (160) for outputting to the inverter (130) in order to adjust the switch frequency. The frequency signal (160) represents the specified switch frequency for the inverter (130).
(FR) L’invention concerne un procédé de fonctionnement d’un onduleur (130) destiné à un système d’entraînement (100). L’onduleur (130) est conçu pour coupler électriquement une source de courant continu (110) à un dispositif d’entraînement (120) du système d’entraînement (100). Le procédé comprend une étape de lecture d’un signal de point de fonctionnement (150) représentant au moins un signal de sortie électrique de l’onduleur (130) qui est requis par le dispositif d’entraînement (120). En outre, le procédé comprend une étape de détermination d’une fréquence de commutation pour l’onduleur (130) à l’aide du signal de point de fonctionnement (150). Le procédé comprend en outre une étape de production d’un signal de fréquence (160) destiné à être délivré à l’onduleur (130) pour régler la fréquence de commutation. Selon l’invention, le signal de fréquence (160) représente la fréquence de commutation spécifique de l’onduleur (130).
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben eines Wechselrichters (130) für ein Antriebssystem (100). Der Wechselrichter (130) ist ausgebildet, um eine Gleichstromquelle (110) mit einer Antriebseinrichtung (120) des Antriebssystems (100) elektrisch zu koppeln. Das Verfahren weist einen Schritt des Einlesens eines Arbeitspunktsignals (150) auf, das zumindest ein durch die Antriebseinrichtung (120) gefordertes elektrisches Ausgangssignal des Wechselrichters (130) repräsentiert. Auch weist das Verfahren einen Schritt des Bestimmens einer Schaltfrequenz für den Wechselrichter (130) unter Verwendung des Arbeitspunktsignals (150) auf. Das Verfahren weist ferner einen Schritt des Bereitstellens eines Frequenzsignals (160) zur Ausgabe an den Wechselrichter (130) auf, um die Schaltfrequenz einzustellen. Dabei repräsentiert das Frequenzsignal (160) die bestimmte Schaltfrequenz für den Wechselrichter (130).
