Abstract:
(EN) The present invention eliminates the need for detecting current in controlling of a power buffer circuit used in a direct power converter. A normalized link-current estimation unit (103e) employs a first value as an estimated value (Idc^/Im*) of a value obtained by normalizing link current flowing from a DC link to an inverter, said first value being calculated using a virtual DC voltage command (Vdc*), the phase (ωt) and amplitude (Vm) of a single-phase AC voltage, and a distribution factor (k). A calculation unit (103f) obtains a second value calculated using the virtual DC voltage command (Vdc*), a rectified voltage (Vrec), and an end-to-end voltage (Vc). If a normalized current command (|sin (ωt)|) is less than the product of the first value and the second value, a normalized charging command (ib*/Im*) is set to zero and a rectifier duty (dr) is obtained by dividing the normalized current command (|sin (ωt)|) by the first value.
(FR) La présente invention élimine le besoin de détecter un courant dans la commande d'un circuit tampon de puissance utilisé dans un convertisseur de puissance directe. Une unité d'estimation de courant de liaison normalisé (103e) utilise une première valeur en tant que valeur estimée (Idc^/Im*) d'une valeur obtenue par normalisation d'un courant de liaison qui passe d'une liaison CC à un onduleur, ladite première valeur étant calculée en utilisant une instruction de tension CC virtuelle (Vdc*), la phase (ωt) et l'amplitude (Vm) d'une tension CA monophasée, et un facteur de distribution (k). Une unité de calcul (103f) obtient une seconde valeur calculée en utilisant l'instruction de tension CC virtuelle (Vdc *), une tension redressée (Vrec) et une tension de bout en bout (Vc). Si une instruction de courant normalisé (|sin (ωt)|) est inférieure au produit de la première valeur et de la seconde valeur, une instruction de charge normalisée (ib*/Im*) est réglée à zéro et un cycle de redresseur (dr) est obtenu en divisant l'instruction de courant normalisé (|sin (ωt)|) par la première valeur.
(JA) 直接形電力変換器に用いられる電力バッファ回路の制御において、電流の検出を不要とする。正規化リンク電流推定部(103e)は、仮想直流電圧指令(Vdc*)、単相交流電圧の位相(ωt)及び振幅(Vm)並びに分配率(k)を用いて計算される第1値を、直流リンクからインバータへ流れるリンク電流を正規化した値の推定値(Idc^/Im*)として採用する。計算部(103f)は、仮想直流電圧指令(Vdc*)、整流電圧(Vrec)、両端電圧(Vc)を用いて計算される第2値を求める。正規化電流指令(|sin(ωt)|)が第1値と第2値との積未満であれば、正規化充電指令(ib*/Im*)は0に設定され、整流デューティ(dr)は正規化電流指令(|sin(ωt)|)を第1値で除して求められる。
