摘要
功率因数校正(power factor correction,PFC)变换器产生的电磁干扰对集成电路造成了严重影响,能否快速的解决PFC变换器的EMI问题,对设备的安全稳定运行至关重要.以Boost PFC电路作为研究对象,分析其电路结构并在电路软件中搭建模型,提取电路中噪声源电流,结合辐射噪声计算公式,对电路模型进行场路协同仿真,得到噪声频谱,并在此基础上提出辐射抑制措施.
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.
