A vehicle-mounted power supply circuit comprises a power switch module (100) and a voltage clamping module (200), and the power switch module (100) and the voltage clamping module (200) are both electrically connected with a power supply so as to receive input voltage from the power supply; the power switch module (100) outputs a first power supply voltage to the first power supply link based on the received input voltage; 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; wherein the power switch module (100) is electrically connected with the vehicle-mounted controller, and the vehicle-mounted controller can directly trigger the power switch module (100) to switch on or switch off the first power supply voltage through a switch control signal.
一种车载供电电路,包括功率开关模块(100)和电压钳位模块(200),功率开关模块(100)和电压钳位模块(200)均与电源电连接,以接收来自电源的输入电压;功率开关模块(100)基于接收到的输入电压向第一供电链路输出第一供电电压;电压钳位模块(200)将接收到的输入电压钳位在预设的电压范围内并向第二供电链路输出第二供电电压;其中,功率开关模块(100)与车载控制器电连接,车载控制器可直接通过开关控制信号触发该功率开关模块(100)开通或关断第一供电电压。
