Peak Interference of Switching Power Supply and Its Suppression [Copy link]

Abstract: This paper introduces several methods of suppressing spike interference. Product trials show that this method is practical to a certain extent.

Keywords: Ripple filter diode
suppression power supply ripple will interfere with the normal operation of electronic equipment, causing failures such as computer crashes, data processing errors and control system failures, causing immeasurable losses to production and scientific research, so measures must be taken to suppress it.

　　There are many reasons for the generation of spikes. The following focuses on analyzing the ripple spikes generated by the reverse recovery time of the diode in the filter circuit, and summarizes several effective suppression measures.
