Abstract
(EN)
Provided is a method for controlling a power conversion device, which can prevent an excessive temperature by suppressing the change of the impedance of a capacitor constituting a rectifier circuit. The power conversion device (1) is provided with: an AC wave generation circuit (5) for generating an AC wave; and a rectifier circuit (7) having a configuration in which a rectifier capacitor (73) and a diode (71) are connected in parallel with each other and rectifying the AC wave generated by the AC wave generation circuit (5). The method for controlling the power conversion device (1) adjusts the AC wave input to the rectifier capacitor (73) so as to suppress the change of the impedance of the rectifier capacitor (73) in accordance with the change of the impedance of the rectifier capacitor (73).

L'invention concerne un procédé de commande d'un dispositif de conversion de courant, qui peut éviter une température excessive en supprimant le changement de l'impédance d'un condensateur constituant un circuit redresseur. Le dispositif de conversion de courant (1) comprend : un circuit de génération d'onde CA (5) destiné à générer une onde CA ; et un circuit redresseur (7) ayant une configuration dans laquelle un condensateur redresseur (73) et une diode (71) sont connectés en parallèle l'un avec l'autre et redressent l'onde CA générée par le circuit de génération d'onde CA (5). Le procédé de commande du dispositif de conversion de courant (1) ajuste l'entrée d'onde CA dans le condensateur redresseur (73) de manière à supprimer le changement de l'impédance du condensateur redresseur (73) en fonction du changement de l'impédance du condensateur redresseur (73).
