一种通用序列汇流排集线器之控制模组，该通用序列汇流排集线器利用一输出开关元件选择性地经由一供电输出端输出一供电电源，并利用一电容稳定该供电输出端之电压，该控制模组包含：一开关；一放电电阻，经由该开关耦接该电容；一控制单元，用来产生一供电控制讯号；以及一逻辑电路，用来依据该供电控制讯号控制该输出开关元件是否输出该供电电源及控制该开关之导通状态；其中，当该供电控制讯号指示该逻辑电路控制该输出开关元件不输出该供电电源，该逻辑电路控制该开关导通，使该电容经由该放电电阻放电，以降低该供电输出端之电压。; a discharge resistor, which is coupled to the capacitor via the switch; a control unit for generating a power supply control signal; and a logic circuit, which controls the output switch whether to output the supplying power and controls the conduction state of the switch according to the power supply control signal. When the power supply control signal indicates that the logic circuit should control the output switch to not output the supplying power, the logic circuit controls the switch to turn on so that the capacitor can discharge through the discharge resistor, causing the voltage at the power supply output to decrease. 【代表图】 【本案指定代表图】：第3图 【本代表图之符号简单说明】： 300 通用序列汇流排集线器 310 集线器控制模组 312 控制单元 314 逻辑电路 316 开关 318 放电电阻 320 输出开关元件 330 电容 340 保护电阻 |
