<p>A power conversion system of this invention comprises line-commutated power converting means in which a line-commutated power conversion circuit that performs line-commutated commutation and a coupling diode are coupled to form a DC circuit and for converting DC power into AC power or AC power into DC power. Further the system comprises self-commutated power converting means in which a self-commutated power conversion circuit coupled to the coupling diode in order to form a DC circuit and for reducing reactive power, or the reactive power and harmonics generated by the line-commutated converting means. Accordingly their respective strengths can be made use of and their mutual weaknesses can complement each other. <IMAGE></p> |
