Title (EN) POWER SOURCE DEVICE AND METHOD FOR CONTROLLING POWER SOURCE DEVICE
(FR) DISPOSITIF SOURCE ÉLECTRIQUE ET PROCÉDÉ DE COMMANDE DE DISPOSITIF SOURCE ÉLECTRIQUE
(JA) 電源装置及び電源装置の制御方法
Abstract:
(EN) This power source device is provided with: a voltage acquisition unit that acquires an input voltage during the on-period of a first switching element; and a determination unit that determines whether a transformer is magnetically saturated on the basis of the input voltage acquired during a first period where the first switching element is on and an input voltage acquired during a second period before the first period by a prescribed period, wherein a control unit controls turning on/off of the first switching element on the basis of the determination result of the determination unit.
(FR) Selon l'invention, un dispositif source électrique comprend : une unité d'acquisition de tension qui acquiert une tension d'entrée pendant la période de fermeture d'un premier élément de commutation ; et une unité de détermination qui détermine si un transformateur est magnétiquement saturé en fonction de la tension d'entrée acquise lors d'une première période pendant laquelle le premier élément de commutation est fermé et une tension d'entrée acquise lors d'une deuxième période en avance d'une période prédéterminée par rapport à la première période, une unité de commande commandant la fermeture/l'ouverture du premier élément de commutation en fonction du résultat de détermination de l'unité de détermination.
(JA) 電源装置は、第1のスイッチング素子がオンの期間での入力電圧を取得する電圧取得部と、第1のスイッチング素子がオンの第1の期間で取得した入力電圧及び第1の期間よりも所定周期前の第2の期間で取得した入力電圧に基づいて、トランスが磁気飽和するか否かを判定する判定部とを備え、制御部は、判定部の判定結果に基づいて第1のスイッチング素子のオン/オフを制御する。
