Abstract:
(EN) A power conversion device according to the present invention converts a DC voltage output from a DC power supply into an AC voltage in a current discontinuous mode. A current controller (6) calculates a target voltage value (VL*) between both ends of a reactor such that a value of current (Iinv) flowing through the reactor becomes a target current value (Iinv*). In the current discontinuous mode, a nonlinear compensator (701) calculates a target conduction ratio (D*) of a current sampling time by using the target voltage value (VL*), a target conduction ratio (D*) before one sampling time, and an output voltage value (Vc) before one sampling time.
(FR) Selon la présente invention, un dispositif de conversion de puissance convertit une sortie de tension continue d'une alimentation en courant continu en une tension alternative dans un mode discontinu actuel. Un régulateur de courant (6) calcule une valeur de tension cible (VL *) entre les deux extrémités d'un réacteur de telle sorte qu'une valeur de courant (Iinv) circulant à travers le réacteur devienne une valeur de courant cible (Iinv *). Dans le mode discontinu actuel, un compensateur non linéaire (701) calcule un rapport de conduction cible (D *) d'un temps d'échantillonnage actuel à l'aide de la valeur de tension cible (VL *), un rapport de conduction cible (D *) avant un temps d'échantillonnage et une valeur de tension de sortie (Vc) avant un temps d'échantillonnage.
(JA) 本発明に係る電力変換装置は、電流不連続モードにおいて、直流電源からの直流電圧を交流電圧に変換する。電流制御器(6)は、リアクトルを流れる電流値(Iinv)が目標電流値(Iinv*)となるようにリアクトルの両端間の目標電圧値(VL*)を算出する。非線形補償器(701)は、電流不連続モードにおいて、目標電圧値(VL*)、1サンプリング時間前の目標通流率(D*)、1サンプリング時間前の出力電圧値(Vc)を用いて、今回のサンプリング時間の目標通流率(D*)を算出する。
