US07643263B2 Controlling over-current from a power supply to a device 有权
控制从电源到设备的过电流

Controlling over-current from a power supply to a device
Abstract:
Apparatus (230) for controlling over-current from a power supply (110) to a device (250), the apparatus comprising two power supply inputs (232a, 232b) and two respective device outputs (234a, 234b), a control circuit (120) having control inputs (126x, 126y) connected across a variable resistance circuit (240) coupled between a said power supply input (232a) and a said respective device output (234a), the control circuit arranged to disconnect one of the power supply inputs (232a) from the respective device output (234a) in response to detecting a predetermined over-current voltage across the variable resistance circuit (240), the resistance of the variable resistance circuit (240) being varied dependent on an over-current setting signal (270) received from the device (250).
Abstract(Chinese):

用于控制从电源（110）到设备（250）的过电流的设备（230），该设备包括两个电源输入（232a，232b）和两个相应的设备输出（234a，234b），控制电路 120），其具有连接在所述电源输入（232a）和所述各个设备输出（234a）之间的可变电阻电路（240）上的控制输入（126x，126y），所述控制电路被布置成断开所述电源 响应于检测到跨越可变电阻电路（240）的预定过电流电压，来自相应设备输出（234a）的输入（232a），可变电阻电路（240）的电阻根据过电流设置而变化 信号（270）从设备（250）接收。
