Abstract:
In this paper, the authors present a methodology that allows them to accommodate the conducted electromagnetic interference (EMI) generated by power factor correctors to international standards in the design step. EMI filter design considerations and EMI predictive procedures are presented. The predictive procedures are based in a family of curves that allows to determine the conducted EMI, generated for the basic PFC converters (boost, buck-boost, Zeta, Sepic, Cuk, and buck converters). Using these curves, one can determine the amplitude of the first harmonic in dB/μV in accordance with the CISPR 16 standard. Therefore, with this information, it is possible to design EMI filters
