Abstract:
(EN) This power conversion apparatus is provided with: a first inverter; a second inverter; and a switching circuit that has a first switch element and a second switch element, wherein, in a state where potentials at a first node on the high side and at a second node on the low side are set equal and potentials at one end of winding wires of two phases among winding wires of n phases (n is an integer of 2 or more) are set equal in the first inverter, the winding wires of two phases are energized by using two legs connected to the other end of the winding wires of the two phases among n legs of the second inverter while switching is performed in the first and second switch elements in the switching circuit at a prescribed duty ratio.
(FR) L'invention concerne un appareil de conversion de puissance qui est pourvu : d'un premier onduleur ; d'un second onduleur ; et d'un circuit de commutation qui comporte un premier élément de commutation et un second élément de commutation, dans un état dans lequel des potentiels au niveau d'un premier nœud sur le côté haut et au niveau d'un second nœud sur le côté bas sont réglés égaux, et où des potentiels à une extrémité de fils d'enroulement de deux phases parmi des fils d'enroulement de n phases (n est un entier supérieur ou égal à 2) sont réglés de manière égale dans le premier onduleur, les fils d'enroulement de deux phases sont alimentés par l'utilisation de deux branches reliées à l'autre extrémité des fils d'enroulement des deux phases parmi n branches du second onduleur, tandis qu'une commutation est effectuée dans les premier et second éléments de commutation dans le circuit de commutation, selon un rapport cyclique prescrit.
(JA) 電力変換装置は、第1インバータと、第2インバータと、第1スイッチ素子および第2スイッチ素子を有する切替回路と、を備え、第1インバータにおいて、ハイサイド側の第1ノードと、ローサイド側の第2ノードとの電位を等しくし、かつ、n(nは2以上の整数)相の巻線のうちの二相の巻線の一端の電位を等しくした状態で、切替回路における第1および第2スイッチ素子を所定のデューティ比でスイッチングしながら、第2インバータのn個のレグのうちの、二相の巻線の他端に接続される2個のレグを用いて二相の巻線を通電する。
