Definitions

  • an input terminal of a boost converter (so-called PWM converter) 2 is connected to a three-phase AC power source 1, and a smoothing capacitor 3 is connected to an output terminal of the converter 2.
  • An input terminal of an inverter 4 is connected to the smoothing capacitor 3, and a direct current motor such as a brushless DC motor 5 is connected to an output terminal of the inverter 4.

  • the converter controller 41 When the power supply voltage abnormality is resolved (YES in S11), the converter controller 41 returns to the first process of S1. At this time, if the brushless DC motor 5 is still in operation (YES in S1) and the converter 2 needs to be boosted (YES in S3), the converter controller 41 checks the boost flag f (S4). ). At this time, since the boost flag f is “0” (YES in S4), the converter controller 41 determines whether or not the boost start condition is satisfied (S5).

Abstract

Selon la présente invention, l'amplification de tension d'un convertisseur est arrêtée lorsqu'une anomalie se produit dans une entrée du convertisseur, et après que l'anomalie est résolue, l'amplification de tension du convertisseur est démarrée dans les conditions où un courant d'entrée jusqu'au convertisseur n'est pas supérieur à une valeur définie et où la vitesse de rotation d'un moteur n'est pas supérieure à une valeur prédéfinie.
