Title (EN) POWER CONVERTING APPARATUS
(FR) APPAREIL DE CONVERSION DE PUISSANCE
(JA) 電力変換装置
Abstract:
(EN) A power converting apparatus configured by connecting single-phase sub-converters (4) in series to the AC input lines of the phases of a 3-phase main converter (3).  The control device (12) that controls the output of the power converter has a CPU which is configured as a current command computing unit (20) that: adjusts the DC voltage command of the main converter (3) so that the DC voltage of the sub-converters tracks a command; and creates an AC current command so that the DC voltage of the main converter (3) tracks the DC voltage command.  The control device (12) controls the AC current by switching the output voltage level of the AC side of the sub-converters (4) so as to minimize the deviation between the AC current command and the instantaneous value of the AC current.
(FR) La présente invention concerne un appareil de conversion de puissance configuré par la connexion série de sous-convertisseurs monophasés (4) sur les lignes d'entrée CA des phases d'un convertisseur principal triphasé (3). Le dispositif de contrôle (12) qui contrôle la sortie du convertisseur de puissance possède une CPU qui est configurée comme une unité informatique de commande de courant (20) qui : ajuste la commande de tension CC du convertisseur principal (3) de sorte que la tension CC des sous-convertisseurs suive une commande ; et crée une commande de courant CC de sorte que la tension CC du convertisseur principal (3) suive la commande de tension CC. Le dispositif de contrôle (12) contrôle le courant CA par la commutation du niveau de tension de sortie du côté CA des sous-convertisseurs (4) de sorte à minimiser l'écart entre la commande de courant CA et la valeur instantanée du courant CA.
(JA)  三相のメインコンバータ(3)の各相の交流入力線に単相のサブコンバータ(4)を直列接続して電力変換器を構成する。電力変換器を出力制御する制御装置(12)では、サブコンバータ(4)の直流電圧が指令に追従するようにメインコンバータ(3)の直流電圧指令を調整し、メインコンバータ(3)の直流電圧が直流電圧指令に追従するように交流電流指令を生成する電流指令値演算部(20)をCPUで構成し、交流電流指令と交流電流瞬時値との偏差が小さくなるようにサブコンバータ(4)の交流側の出力電圧レベルを切り替えることで交流電流を制御する。
