Abstract:
(EN) A power converter 1 for supplying an AC voltage converted from a DC voltage to a load, wherein the power converter 1 is provided with an inverter 12 for receiving a PWM signal and applying an AC voltage to the load, and an inverter control unit 13 for generating the PWM signal and feeding the PWM signal to the inverter 12. The frequency of the PWM signal is an integer multiple of the frequency of the AC voltage. The AC voltage has, in each period of the AC voltage, a plurality of positive pulses and a plurality of negative pulses. The number of the positive pulses and the number of the negative pulses are identical. It becomes possible to minimize any distortion in the current flowing through a motor.
(FR) L'invention concerne un convertisseur de puissance (1) pour l'alimentation en tension en CA convertie à partir d'une tension en CC d'une charge, le convertisseur de puissance (1) comportant un onduleur (12) pour la réception d'un signal à MID et l'application d'une tension en CA à la charge, et une unité de commande (13) d'onduleur pour la génération du signal à MID et l'émission du signal à MID vers l'onduleur (12). La fréquence du signal à MID est un multiple entier de la fréquence de la tension en CA. La tension en CA présente, dans chaque période de la tension en CA, une pluralité d'impulsions positives et une pluralité d'impulsions négatives. Le nombre d'impulsions positives et le nombre d'impulsions négatives sont identiques. Il devient possible de minimiser toute distorsion dans le courant circulant à travers un moteur.
(JA) 直流電圧から変換された交流電圧を負荷に供給する電力変換装置1において、PWM信号を受け取り、負荷に交流電圧を印加するインバータ12と、PWM信号を生成し、インバータ12にPWM信号を供給するインバータ制御部13と、を備える。PWM信号の周波数は、交流電圧の周波数の整数倍であり、交流電圧は、交流電圧の1周期に複数の正パルスと複数の負パルスとを有し、正パルスの数と負パルスの数とは等しい。モータに流れる電流の歪みを抑制することができる。
