Abstract:
(EN) A power conversion device is provided with: a first arm (31) having a switching element (311) and another switching element (312) which are connected in series; a second arm (32) having a switching element (321) and another switching element (322) which are connected in series and connected in parallel with the first arm (31); a reactor (2) having one end connected to the switching element (311) and the switching element (312) and the other end connected to an AC power supply 1; and a smoothing capacitor (4) connected in parallel with the first arm (31) and the second arm (32). The switching element (311) and the switching element (312) are more excellent in loss characteristics occurring at every switching than the switching element (321) and the switching element (322).
(FR) L'invention concerne un dispositif de conversion de puissance comprenant : un premier bras (31) comportant un élément de commutation (311) et un autre élément de commutation (312) connectés en série; un second bras (32) comportant un élément de commutation (321) et un autre élément de commutation (322) connectés en série et connectés en parallèle au premier bras (31); une bobine de réactance (2) dont une extrémité est connectée à l'élément de commutation (311) et à l'élément de commutation (312) et dont l'autre extrémité est connectée à une alimentation en courant alternatif 1; et un condensateur de lissage (4) connecté en parallèle au premier bras (31) et au second bras (32). L'élément de commutation (311) et l'élément de commutation (312) sont plus performants en termes de caractéristiques de perte se produisant à chaque commutation que l'élément de commutation (321) et l'élément de commutation (322).
(JA) 直列接続されるスイッチング素子(311)及びスイッチング素子(312)を有する第1のアーム(31)と、直列接続されるスイッチング素子(321)及びスイッチング素子(322)を有し、第1のアーム(31)に並列接続される第2のアーム(32)と、一端がスイッチング素子(311)及びスイッチング素子(312)に接続され、他端が交流電源1に接続されるリアクタ(2)と、第1のアーム(31)及び第2のアーム(32)に並列接続される平滑コンデンサ(4)とを備え、スイッチング毎に発生するスイッチング素子(311)及びスイッチング素子(312)の損失特性は、スイッチング毎に発生するスイッチング素子(321)及びスイッチング素子(322)の損失特性よりも優れる。
