<P>PROBLEM TO BE SOLVED: To provide a power conversion device that reliably suppresses harmonic components to be suppressed in an input current from an AC power supply side. <P>SOLUTION: The power conversion device includes: a conversion section (4) having a plurality of switching elements (Sr, Ss, St, Su, Sv, Sw, Sx, Sy, Sz), converting power from the AC power supply (6) into AC power of a predetermined frequency by a switching action of the plurality of switching elements (Sr, Ss, St, Su, Sv, Sw, Sx, Sy, Sz), and outputting the AC power to a load (7); and a control section (10) for controlling the plurality of switching elements (Sr, Ss, St, Su, Sv, Sw, Sx, Sy, Sz) such that specific orders of harmonic components (Iin2, Iin3, Iin4,...) of harmonic components (Iin2, Iin3, Iin4,...) included in an input current (Iin) from the AC power supply (6) are individually suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
