US07642677B2 Controlling inrush current from a power supply to a load 失效
控制从电源到负载的浪涌电流

Controlling inrush current from a power supply to a load
Abstract:
Apparatus (100) for controlling inrush current from a power supply (250) to a load (255), the apparatus comprising a first (105a) and a second (105b) power supply input and a first (110a) and a second (110b) load output, a semiconductor device (115) coupled between the first power supply input (105a) and the first load output (110a), a control circuit (120) having a control circuit input (125) coupled to the first load output (110a) and a control circuit output (130) coupled to a conductance control node (135) of the semiconductor device (115), wherein, in use, when a load (255) is connected across the first load output (110a) and the second load output (110b), the control circuit (120) provides a control signal to the conductance control node (130) to thereby progressively vary the conductance of the semiconductor device (115) from a low conductance state to a high conductance state in response to a load signal being provided to the control circuit input (125) indicating that a load current (Isd) flowing through the semiconductor device (115) has exceeded a pre-determined threshold.
Abstract(Chinese):

用于控制从电源（250）到负载（255）的浪涌电流的设备（100），该设备包括第一（105a）和第二（105b）电源输入和第一（110a）和第二（110b） ）耦合在所述第一电源输入端（105a）和所述第一负载输出端（110a）之间的半导体器件（115），控制电路（120），其具有耦合到所述第一负载输出端的控制电路输入端（125） 110a）和耦合到半导体器件（115）的电导控制节点（135）的控制电路输出（130），其中在使用中，当负载（255）跨越第一负载输出（110a）和 第二负载输出（110b），控制电路（120）向电导控制节点（130）提供控制信号，从而逐渐改变半导体器件（115）从低电导状态到高电导状态的电导响应 提供给控制电路输入（125）的负载信号，指示负载c 流过半导体器件（115）的流量（Isd）已经超过预定阈值。
