<P>PROBLEM TO BE SOLVED: To provide an apparatus for transmitting electric power which can be manufactured in a low cost, and at the same time can suppress an undesirable AC-current component in a DC-voltage connecting circuit. <P>SOLUTION: The apparatus 1 for transmitting the power is equipped with a first electric-power converting device 2 for converting an AC voltage to a DC voltage. The electric-power converting device 2 is connected at least to one second electric-power converting device for converting the DC voltage to the AC voltage through a DC-voltage connecting circuit 4. Further, the apparatus 1 has a smoothing reactor L<SB>G</SB>designed to smooth the DC voltage, and a limiting filter 9 to limit the AC-current component in the DC-voltage connecting circuit 4. In the apparatus 1 for electric-power transmission, the smoothing reactor L<SB>G</SB>is utilized at least partially as a part of the limiting filter 9. <P>COPYRIGHT: (C)2010,JPO&INPIT |
