Title (EN) CONTROL DEVICE FOR DIRECT POWER CONVERTER
(FR) DISPOSITIF DE COMMANDE POUR CONVERTISSEUR D'ÉNERGIE À COURANT CONTINU
(JA) 直接型電力変換器用制御装置
Abstract:
(EN) The present invention suppresses a voltage fluctuation across the ends of a buffer capacitor of a power buffer circuit of a direct power converter in the event of a fluctuation in the electrostatic capacitance of the buffer capacitor. This control device (10) is provided with a charge control unit (103). The charge control unit (103) has an amplitude determination part (103a), a charge command generation part (103b), and charge operation control part (103c). The amplitude determination part (103a) performs at least proportional integral control with respect to the deviation (∆Vc) between an average voltage command value (Vc*), that is, a command for the average value of voltage (Vc) across the ends of the buffer capacitor, and the voltage (Vc) across the ends, and determines the amplitude (Im) of an input current to the converter. The charge command generation part (103b) multiplies the amplitude (Im) by a function (F (θ)) that is determined in accordance with a discharge duty cycle (dc), a rectification duty cycle (drec), and a power distribution ratio and determines a charge command (iL*). The charge operation control part (103c) controls the charging operation of the buffer capacitor on the basis of the charge command (iL*).
(FR) La présente invention supprime une fluctuation de tension aux bornes d'un condensateur tampon d'un circuit tampon d'énergie d'un convertisseur d'énergie à courant continu dans le cas d'une fluctuation de la capacité électrostatique du condensateur tampon. Le dispositif de commande (10) selon l'invention est pourvu d'une unité de commande de charge (103). L'unité de commande de charge (103) comprend une partie de détermination d'amplitude (103a), une partie de génération de commande de charge (103b) et une partie de commande d'opération de charge (103c). La partie de détermination d'amplitude (103a) effectue au moins une régulation proportionnelle intégrale par rapport à l'écart (∆Vc) entre une valeur de commande de tension moyenne (Vc*), c'est-à-dire une commande pour la valeur moyenne de la tension (Vc) aux bornes du condensateur tampon, et la tension (Vc) aux bornes, et détermine l'amplitude (Im) d'un courant d'entrée vers le convertisseur. La partie de génération de commande de charge (103b) multiplie l'amplitude (Im) par une fonction (F(θ)) qui est déterminée en fonction d'un rapport cyclique de décharge (dc), d'un rapport cyclique de redressement (drec) et d'un taux de distribution d'énergie, et détermine une commande de charge (iL*). La partie de commande d'opération de charge (103c) commande l'opération de charge du condensateur tampon en s'appuyant sur la commande de charge (iL*).
(JA)  直接型電力変換器が備える電力バッファ回路において、バッファコンデンサの静電容量に変化が生じても、その両端電圧の変動を抑制する。制御装置(10)は充電制御部(103)を備える。充電制御部(103)は、振幅決定部(103a)と、充電指令生成部(103b)と、充電動作制御部(103c)とを有する。振幅決定部(103a)は、バッファコンデンサの両端電圧(Vc)の平均値についての指令値たる平均電圧指令値(Vc*)と両端電圧(Vc)との偏差(ΔVc)に対して、少なくとも比例積分制御を行って、コンバータに入力する入力電流の振幅(Im)を決定する。充電指令生成部(103b)は、放電デューティ(dc)、整流デューティ(drec)、電力の分配率に応じて決定される関数(F(θ))を振幅(Im)に乗じて、充電指令(iL*)を決定する。充電動作制御部(103c)は、充電指令(iL*)に基づいてバッファコンデンサを充電する動作を制御する。
