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.
Le convertisseur de puissance selon la présente invention comprend un moyen de conversion à commutation par le réseau dans lequel un circuit de conversion à commutation par le réseau et une diode de couplage sont couplés pour former un circuit CC et pour convertir la puissance CC en puissance CA et vice versa. De plus, le convertisseur de puissance comprend un moyen de conversion à auto-commutation dans lequel un circuit de conversion à auto-commutation est couplé à la diode de couplage pour former un circuit CC et pour atténuer la puissance réactive ou la puissance réactive et les harmoniques générées par le moyen de conversion à commutation par le réseau. Ainsi, on peut exploiter les forces respectives des différents composants et compenser les faiblesses communes.
