Automatic Detection Device for Ripple of Mine Power Supply

Power supply ripple, as one of the important indexes to measure the quality of power supply, has an important influence on the stability and reliability of mine electronic equipment. Because of its special working environment and load requirements, mine power supply puts forward higher requirements for the suppression and detection of power supply ripple. This paper expounds the generation mechanism of power supply ripple, analyzes the difference between linear power supply and switching power supply in ripple generation, and puts forward an automatic detection device for mine power supply ripple. The hardware of the device is highly integrated with high-precision detection equipment such as oscilloscope, source voltage and electronic load, and the software adopts virtual instrument technology to design an automatic detection system for mine power supply ripple. The experimental results show that the automatic detection device for mine power supply ripple has been improved in accuracy, stability and automation, which provides a more efficient and reliable solution for mine power supply ripple detection.
