Beschreibung
Zusammenfassung:	The present invention may comprise: a direct current-to-alternating current conversion unit having at least two multi-level converters each converting input direct-current power into alternating-current power; a Scott transformer which operates at a medium frequency of hundreds of Hz to tens of thousands of Hz so that a voltage level of the alternating-current power from each of the at least two multi-level converters of the direct current-to-alternating current conversion unit is transformed into three-phase alternating-current power to be output; and an alternating current-to-direct current conversion unit for converting the three-phase alternating-current power from the Scott transformer into direct-current power.
