Beschreibung
Zusammenfassung:	The power conversion device of the present invention comprises a power diode rectifier (REC) whose AC terminal is connected through an AC reactor (Ls) with an AC power source; voltage-type self-commutated power converters (CNV) whose AC terminals are connected with the AC terminal of this power diode rectifier through a recovery current suppression reactor (La); and a DC smoothing capacitor (Cd) connected between a DC common terminal of this voltage type self-commutated power converter and the power diode rectifier, with a load device connected in parallel therewith.
