Title (EN) POSITIVE/NEGATIVE POWER SUPPLY OUTPUT CONTROL APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE COMMANDE DE SORTIE D'ALIMENTATION POSITIVE/NÉGATIVE
(ZH) 一种正负电源输出控制装置及方法
Abstract:
(EN) A positive/negative power supply output control apparatus. The apparatus comprises a DC-DC power supply module (2), an energy storage inductor (L2), an energy-storage and energy-discharging capacitor (C8), a capacitor charging-discharging direction controlled bidirectional diode (D3), a positive power supply output module (3), a negative power supply output module (4), and a direct current power supply module (1). The output of the positive/negative power supply is controlled by the off and on of a switching transistor in the DC-DC power supply module (2), and then the output of positive and negative power supplies can be implemented simultaneously by using one DC-DC chip. The control apparatus and method are flexible and simple in control modes, can reduce design costs and power supply power consumption, and has a great prospect application and popularization prospect.
(FR) L'invention concerne un appareil de commande de sortie d'alimentation positive/négative. L'appareil comprend un module d'alimentation électrique CC-CC (2), un inducteur de stockage d'énergie (L2), un condensateur de stockage d'énergie et de décharge d'énergie (C8), une diode bidirectionnelle commandée en direction de charge-décharge de condensateur (D3), un module de sortie d'alimentation positive (3), un module de sortie d'alimentation négative (4), et un module d'alimentation en courant continu (1). La sortie de l'alimentation positive/négative est commandée par l'arrêt et l'activation d'un transistor de commutation dans le module d'alimentation CC-CC (2), puis la sortie d'alimentations positives et négatives peut être mise en œuvre simultanément à l'aide d'une puce CC-CC. L'appareil et le procédé de commande sont souples et simples en modes de commande, peuvent réduire les coûts de conception et la consommation d'énergie d'alimentation, et présentent une grande perspective d'application et de popularisation.
(ZH) 一种正负电源输出控制装置,该装置包括DC-DC电源模块(2),储能电感(L2),储能放能电容(C8),电容充放电方向控制双向二极管(D3),正电源输出模块(3),负电源输出模块(4),直流电源模块(1)。通过DC-DC电源模块(2)中的开关管的截止与导通来控制正负电源的输出,进而达到使用一个DC-DC芯片即可同时实现正、负电源输出的目的。该控制装置及方法,其控制模式灵活简洁,降低了设计成本及电源功耗,具有较大的应用推广前景。
