摘要： A vehicle-mounted power supply circuit, comprising a power switch module (100) and a voltage clamp module (200). The power switch module (100) and the voltage clamp module (200) are both electrically connected to a power supply to receive an input voltage from the power supply. On the basis of the received input voltage, the power switch module (100) outputs a first power supply voltage to a first power supply link. The voltage clamping module (200) clamps the received input voltage within a preset voltage range, and outputs a second power supply voltage to a second power supply link. The power switch module (100) is electrically connected to a vehicle-mounted controller, and the vehicle-mounted controller, by means of a switch control signal, may directly trigger the power switch module (100) to turn on or off the first power supply voltage.

摘要： A power source control circuit (300) and a power steering system (500). The power source control circuit (300) comprises: a signal input circuit (310), which comprises at least two input ends, wherein each of the at least two input ends is used for collecting a first control signal, which indicates whether an external device corresponding to the input end is abnormal; and a control circuit (330), which is used for generating, according to the first control signals collected by each of the at least two input ends, a second control signal, which is used for controlling the turning-off of a power source (520).
