Suppression Method of Electromagnetic Interference for Switching Power Supply of Mine Sensor

More Information
  • Published Date: March 19, 2017
  • We analyze the main source of electromagnetic interference of typical mine sensor switching power supply, propose specific interference suppression methods, set up a test circuit. The simulation analysis and experiment validation show that this method can largely eliminate the output signal peak interference of switching power supply, and has obvious inhibitory effect on common mode and differential mode noises of switching power supply circuit, which has guiding significance for enhancing the reliability of coal mine sensor.
