| Abstract: | The electromagnetic interference caused by a power factor correction(PFC)converter has made a great influence on the integrated circuit,and whether to rapidly solve the EMI problem of a PFC converter is vital to the safe and stable operation of the device. Therefore,this paper takes Boost PFC circuit as the research object,analyzes its circuit structure and builds a model in circuit software,extracts the noise source current in the circuit,combines the radiation noise calculation formula,and performs field-path co-simulation on the circuit model to obtain the noise spectrum. Based on this,radiation suppression measures are proposed. |
