Protection circuit unit for power supply system

电源系统的保护电路装置

Abstract

The utility model relates to a protection circuit device for a power source system, which is used in ordinary circuits which is provided with a power supply system, particularly protecting switch motions of a power source. The utility model comprises an anti-bounce circuit, a selection circuit, a sustain circuit and an isolating circuit, wherein, the anti-bounce circuit receives signals which are input after a bounce switch is activated, which can eliminate misoperation possibly caused by the phenomenon of tremors generated by the input signals. The selection circuit receives outputs of the output end of the anti-bounce circuit, and outputs a signal which can control the opening and the closure of a system power source. The sustain circuit can sustain the supply of a normal working power source which is required in a follow-up connecting circuit. The isolating circuit can supply the isolation to a main power source, and can receive an input signal to imperatively turn off the system power source.
本实用新型为一种电源系统的保护电路装置,可应用在一般具有电源供应系统的电路中,特别是保护电源的开关动作。本实用新型包括有一防弹跳电路、一选择电路、一维持电路以及一隔离电路。其中该防弹跳电路接受一弹跳开关被激活之后所输入的讯号,并且对于该输入讯号所产生的震颤现象而可能造成的误动作予以消除。选择电路是接受防弹跳电路输出端的输出,并输出对一系统电源的开启或关闭进行控制的信号。维持电路则使得可对后续连接电路中所需要的一正常工作电源的供应得以维持。隔离电路则可提供对一主要电源的隔离,以及可接受一输入讯号以对该系统电源强制性的关闭。
