Abstract:
(EN) This power converter is provided with: a rectifier 3 for converting alternating-current power from an alternating-current power source 1 to direct-current power; a short-circuit unit 30 for short-circuiting the alternating-current power source 1 via a reactor 2; and a control unit 20 for controlling the short-circuiting operation of the short-circuit unit 30. The control unit 20 changes the number of short-circuiting operations in a half-period of the alternating-current power source output waveform on the basis of a load condition, and causes the delay time from the zero-cross point of the alternating-current power source output waveform until the short-circuiting after the number of short-circuiting operations is changed to be different than the delay time from the zero-cross point of the alternating-current power source output waveform until the short-circuiting before the number of short-circuiting operations is changed.
(FR) La présente invention concerne un convertisseur électrique doté : d'un redresseur (3) destiné à convertir le courant alternatif provenant d'une source de courant alternatif (1) en courant continu ; d'une unité de court-circuitage (30) permettant de court-circuiter la source d'alimentation en courant alternatif (1) par l'intermédiaire d'un réacteur (2) ; et d'une unité de commande (20) destinée à commander l'opération de court-circuitage de l'unité de court-circuitage (30). L'unité de commande (20) change le nombre d'opérations de court-circuitage dans une demi-période de la forme d'onde de sortie de la source de courant alternatif sur la base d'une condition de charge et réduit le temps de délai depuis le point de passage à zéro de la forme d'onde de sortie de la source de courant alternatif jusqu'au court-circuitage après la modification du nombre d'opérations de court-circuitage pour qu'il soit différent du temps de délai depuis le point de passage par zéro de la forme d'onde de sortie de la source de courant alternatif jusqu'au court-circuitage avant la modification du nombre d'opérations de court-circuitage.
(JA) 交流電源1からの交流電力を直流電力に変換する整流器3、リアクタ2を介して交流電源1を短絡する短絡部30および短絡部30の短絡動作を制御する制御部20を備える。制御部20は、負荷条件に基づいて交流電源出力波形の半周期中における短絡動作の回数を変化させ、かつ、短絡動作の回数を変化させた後の交流電源出力波形のゼロクロス点から短絡までの遅延時間を、短絡動作の回数を変化させる前の交流電源出力波形のゼロクロス点から短絡までの遅延時間と異ならせる。
