Abstract
(EN)
In a power conversion apparatus 20, voltage-adjusted DC power is supplied to a DC bus 30 from a voltage conversion circuit 21 that adjusts the voltage of output power from a DC power source 10. An inverter 22 converts the DC power of the DC bus 30 into AC power, and supplies the converted AC power to a power system 46. A control unit 23 is for controlling the inverter 22. When output suppression is necessary, the control unit 23 suppresses the AC power supplied by the inverter 22, to boost the voltage of the DC bus 30.
(FR)
Dans un appareil de conversion de puissance 20, une puissance en courant continu réglée en tension est fournie à un bus CC 30 à partir d'un circuit de conversion de tension 21 qui règle la tension de la puissance de sortie en provenance d'un bloc d'alimentation en courant continu 10. Un onduleur 22 convertit la puissance en courant continu du bus CC 30 en une puissance en courant alternatif, et fournit la puissance en courant alternatif convertie à un système d'alimentation 46. Une unité de commande 23 est destinée à commander l'onduleur 22. Lorsqu'une suppression de sortie est nécessaire, l'unité de commande 23 supprime la puissance en courant alternatif fournie par l'onduleur 22, pour amplifier la tension du bus CC 30.

電力変換装置20において、直流バス30は、直流電源10の出力電力の電圧を調整する電圧変換回路21から電圧が調整された直流電力が供給される。インバータ22は、直流バス30の直流電力を交流電力に変換し、変換した交流電力を電力系統46へ供給する。制御部23は、インバータ22を制御するためのものである。制御部23は、出力抑制の必要な場合に、インバータ22の供給する交流電力を抑制して、直流バス30の電圧を上昇させる。
