Abstract: front page image
(EN)The present invention relates to a switching-type power supply apparatus and to a control circuit having a power factor-correcting function. One or two switching elements are controlled so as to be opened/closed in accordance with a switching period and time corresponding to the feedback from a second power-converting unit so as to correct a power factor by means of a first power-converting unit such that input current having low harmonic distortion can flow, and at the same time, a second power-converting unit performs an operation to stabilize output voltage and current. Thus, the switching-type power supply apparatus and the control circuit of the present invention may provide the advantages of a simple configuration, small size, and reduced costs as compared to conventional technologies that require two independent control outputs and two independent switching elements.
(FR)La présente invention concerne un appareil d'alimentation du type à découpage et un circuit de commande doté d'une fonction de correction du facteur de puissance. Un ou deux éléments de commutation est/sont commandé(s) de façon à être ouvert(s)/fermé(s) en fonction d'une période et d'un moment de commutation correspondant à la réaction d'une seconde unité de conversion de puissance de manière à corriger un facteur de puissance au moyen d'une première unité de conversion de puissance, de telle façon que le courant d'entrée à faible taux d'harmoniques puisse circuler, cependant qu'une seconde unité de conversion de puissance exécute une opération de stabilisation de la tension et du courant de sortie. Ledit appareil d'alimentation du type à découpage et le circuit de commande de l'invention peuvent ainsi assurer les avantages d'une configuration simple, d'une taille réduite et de coûts réduits comparativement aux techniques classiques qui requièrent deux sorties de commande indépendantes et deux éléments de commutation indépendants.
(KO)본 발명은 역률보정 기능을 가지는 스위칭형 전원장치 및 제어회로에 관한 것으로, 제2전력변환부로부터의 피드백에 대응하는 스위칭 주기와 도통시간으로 1 개 혹은 2 개의 스위칭소자를 개폐 제어하여 제1전력변환부에 의해 역률을 보정하여 Harmonic distortion이 낮은 입력전류가 흐르도록 하고, 동시에 제2전력변환부에 의해 출력 전압 및 전류를 안정화시키는 동작을 수행하게 함으로써, 2개의 독립된 제어출력과 2개의 독립된 스위칭소자를 필요로 했던 종래의 기술에 비해 훨씬 간단하고 소형화되고 원가가 절감되는 장점을 제공하는 것이다.
