Abstract:
(EN) A soft start circuit, and a power board and a service single board having the circuit. The soft start circuit comprises: a soft start MOS transistor (100), a soft start driving control transistor (200) and a power supply circuit (300). The power supply circuit (300) is configured to power the soft start driving control transistor (200) and determine a delay period between turning off and turning on the transistor (200). Upon power-on at a power input end, the power supply circuit (300) is configured to power the transistor (200), and to turn on the transistor (200) after the delay period, and the soft start MOS transistor (100) is activated when the transistor (200) is turned on. Upon power-off at the power input end, the power supply circuit (300) is configured to stop powering the transistor (200) and to turn off the transistor (200), so as to deactivate the soft start MOS transistor (100).
(FR) L’invention concerne un circuit de démarrage souple, et une carte de puissance et une carte unique de service ayant le circuit. Le circuit de démarrage souple comprend : un transistor MOS (100) de démarrage souple, un transistor de contrôle d’attaque (200) de démarrage souple et un circuit d’alimentation électrique (300). Le circuit d’alimentation électrique (300) sert à alimenter en puissance le transistor de contrôle d’attaque (200) de démarrage souple et à déterminer une période de retard entre la désactivation et l’activation du transistor (200). Lors de l’activation d’alimentation à une extrémité d’entrée de puissance, le circuit d’alimentation électrique (300) sert à alimenter en puissance le transistor (200), et à activer le transistor (200) après la période de retard, et le transistor MOS (100) de démarrage souple est activé lorsque le transistor (200) est activé. Lors de la désactivation d’alimentation à l’extrémité d’entrée de puissance, le circuit d’alimentation électrique (300) sert à arrêter l’alimentation du transistor (200) et à désactiver le transistor (200), afin de désactiver le transistor MOS (100) de démarrage souple.
(ZH) 一种缓启动电路及包含该电路的电源板和业务单板,该缓启动电路,包括:缓启动MOS管(100)、缓启动驱动控制三极管(200)和供电电路(300),其中,供电电路(300),设置为对缓启动驱动控制三极管(200)供电并决定所述三极管(200)从关断到导通的延迟时长;从电源输入端上电开始,所述供电电路(300)设置为为所述三极管(200)供电并使所述三极管(200)经过所述延迟时长而导通,所述三极管(200)导通时启动缓启动MOS管(100);从电源输入端掉电开始,所述供电电路(300)设置为停止为所述三极管(200)供电并使所述三极管(200)断开以关闭缓启动MOS管(100)。
