Because high-frequency current and voltage change exists in the high-frequency switching power supply, EMI is conducted in the coupling mode of conducting wire and parasitic inductance and parasitic capacitance, and meanwhile, the change of the current and the voltage is accompanied by the change of magnetic field and electric field to form radiation EMI, all topological switching power supplies have the problem of electromagnetic interference. In a specific power circuit, the main reason for causing electromagnetic interference is that the transformer has a large leakage inductance and parasitic capacitance due to the unreasonable structural design, which causes the high-frequency and rapid change of the drain current and voltage of the MOS transistor, and serious electromagnetic interference is generated by the coupling of the parasitic capacitance of the transformer.
