Title (EN) POWER CONVERSION DEVICE
(FR) DISPOSITIF DE CONVERSION D'ALIMENTATION
(JA) 電力変換装置
Abstract:
(EN) According to the present invention, a power conversion device having a plurality of switching elements (Su, Sv, Sw, Sx, Sy, Sz) is provided with a control unit (40) for controlling a switching operation. In a waveform obtained by extracting and synthesizing a second harmonic, a fourth harmonic, and a sixth harmonic with a power supply frequency as a fundamental frequency from a waveform of an absolute value of a motor current vector, the control unit (40) controls the switching elements (Su, Sv, Sw, Sx, Sy, Sz) such that the waveform becomes a waveform in which two or more maximum points appear in a power supply half cycle.
(FR) Le dispositif de conversion d'alimentation selon la présente invention, qui comporte une pluralité d'éléments de commutation (Su, Sv, Sw, Sx, Sy, Sz), est pourvu d'une unité de commande (40) pour commander une opération de commutation. Dans une forme d'onde obtenue par l'extraction et la synthèse d'une deuxième harmonique, d'une quatrième harmonique et d'une sixième harmonique à l'aide d'une fréquence d'alimentation en tant que fréquence fondamentale, à partir d'une forme d'onde d'une valeur absolue d'un vecteur de courant de moteur, l'unité de commande (40) commande les éléments de commutation (Su, Sv, Sw, Sx, Sy, Sz) de sorte que la forme d'onde devienne une forme d'onde dans laquelle au moins deux points maximaux apparaissent dans un demi-cycle d'alimentation électrique.
(JA) 複数のスイッチング素子(Su,Sv,Sw,Sx,Sy,Sz)を有した電力変換装置において、スイッチング動作を制御する制御部(40)を設ける。制御部(40)は、モータ電流ベクトルの絶対値の波形から電源周波数を基本波周波数とする2次調波、4次調波、及び6次調波を抽出して合成した波形において、電源半周期において極大点が2つ以上出現する波形になっているように、スイッチング素子(Su,Sv,Sw,Sx,Sy,Sz)を制御する。
