Problems solved by technology

[0002] The power circuit is an important part of the motherboard. Its function is to convert the voltage of the current delivered by the host power supply, and convert the voltage to the core voltage value that the CPU can accept, so that the CPU can work normally. The power circuit is in the current-voltage During the conversion process, a large conduction loss will be generated, which will cause the temperature of the main board to rise. Although there is a cooling device in the main board, the temperature of the main board will still continue to rise. It will cause the system to slow down, and even trigger system protection and power failure, seriously affecting the work efficiency of large-scale equipment in the factory

Abstract

The invention discloses a power supply loop monitoring system. The system comprises a power acquisition module and a screening calibration module. The power acquisition module uses a power sampler J1with a model of YK-3D3 to acquire an output power signal of a power supply loop. The screening calibration module uses a triode Q1 and a triode Q2 to detect the output signal amplitude of the power acquisition module. Meanwhile, an operational amplifier AR2, a diode D2 and a diode D3 are used for forming a peak value circuit to screen peak value signals; one path of signal is subjected to phase shift by a phase shift circuit consisting of an operational amplifier AR3 and a capacitor C3; an inductor L1 and capacitors C4 to C6 are used for forming a frequency modulation circuit for stabilizing the signal frequency for the two paths of signals; and finally, the two paths of signals are input into a buffer circuit composed of an operational amplifier AR4 and a resistor R16 together, the signals are buffered and then sent into the power supply loop monitoring system terminal through a signal emitter E1, an early warning signal is conveniently triggered by the power supply loop monitoring system terminal, and the temperature of a power supply loop mainboard is prevented from being too high.
