Tool for conducted EMI and filter design

In this paper a simulation tool that allows us to determine the conducted electromagnetic interference (EMI), generated for the basic PFP converters (Cuk, buck, boost, buck-boost, sepic, and zeta converters) will be presented. Using this software, we can determine full EMI spectrum in dB//spl mu/V in accordance with the CISPR 16 standard. An EMI filter design methodology that allow us to accommodate the conducted electromagnetic interference (EMI) generated by power factor correctors to international standards in the design step is also presented. Therefore, this can be an useful aid for power electronics designers.
