Abstract
(EN) A non-contact power supply device 1 is provided with: an inverter 8 for converting power supplied from a power supply 2 into a predetermined AC power; feeders 12A, 12B provided on a track rail T and transmitting AC power to a ceiling conveyor 20; a filter circuit 9 including a reactor RT2 and a capacitor C2; and a control unit 15 for performing power control of AC power which is to be supplied to the feeders 12A, 12B. The control unit 15 obtains a current value output from the inverter 8 by changing the switching frequency of a plurality of switching elements 14 of the inverter 8 in a state in which a current having a predetermined value flows through the feeders 12A, 12B, and sets and outputs the reactor value of the reactor RT2 and the capacitance value of the capacitor C2 on the basis of the switching frequency at which the current value becomes the minimum value.
(FR) Un dispositif d'alimentation électrique sans contact (1) comporte : un onduleur (8) destiné à convertir une puissance fournie par une alimentation électrique (2) en une puissance en CA prédéterminée ; des dispositifs d'alimentation (12A, 12B) disposés sur un rail de voie ferrée (T) et transmettant une puissance en CA à un transporteur de plafond (20) ; un circuit de filtrage (9) comportant un réacteur (RT2) et un condensateur (C2) ; et une unité de commande (15) destinée à réaliser une commande de puissance de puissance en CA qui doit être fournie aux dispositifs d'alimentation (12A, 12B). L'unité de commande (15) obtient une valeur de courant fournie en sortie depuis l'onduleur (8) en modifiant la fréquence de commutation d'une pluralité d'éléments de commutation (14) de l'onduleur (8) dans un état dans lequel un courant présentant une valeur prédéterminée circule à travers les dispositifs d'alimentation (12A, 12B), et établit et délivre en sortie la valeur de réacteur du réacteur (RT2) et la valeur de capacité du condensateur (C2) sur la base de la fréquence de commutation au niveau de laquelle la valeur de courant devient la valeur minimale.
(JA) 非接触給電装置1は、電源2から供給される電力を所定の交流電力に変換するインバータ8と、軌道レールTに設けられ、天井搬送車20に交流電力を送電する給電線12A,12Bと、リアクトルRT2及びコンデンサC2を含むフィルタ回路9と、給電線12A,12Bに供給する交流電力の電力制御を行う制御部15と、を備え、制御部15は、給電線12A,12Bに所定値の電流を流した状態で、インバータ8の複数のスイッチング素子14のスイッチング周波数を変化させてインバータ8から出力される電流値を取得し、当該電流値が最小値となるスイッチング周波数に基づいて、リアクトルRT2のリアクトル値及びコンデンサC2の静電容量値を設定して出力する。
