The electromagnetic pulse suppression of high-frequency switching power supply means that the electromagnetic pulse of high-frequency switching power supply is provided by Tongke Electric. Since the surge mainly comes from lightning, the suppression of electromagnetic pulse mainly uses corresponding measures to induce the device in a very short time. A large amount of pulse energy is discharged to the safety ground to protect the entire equipment. Generally, three methods such as a shunt varistor, a Zener diode, and a gas discharge tube are used for suppression. If the equipment requirements are low, one of the methods may be adopted. If the requirements are high, the three are required to be used together. In order to achieve a satisfactory result.
