![]() ![]() The influence of the EMI injected into the AC line by the power converters working as Power Factor Preregulators (PFP) in the electronic design is becoming more and more important. These fees fade into insignificance when compared with the impact of the resulting delay on product time to market. Keeping this in mind, is important to minimize the EMI failures in the design time, because the real cost of EMI compliance failing is not the charge made to EMC credential laboratories for testing and re-testing, that can be expensive, with Test House fees up to U$ 1,500.00 per day. ![]() INTRODUCTION A crucial task in the recent years has been the reduction of the product development time, because the product lifetime has become shorter quickly. Therefore, this can be an useful aid for power electronics designers. 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. Using this Software, we can determine full EMI spectrum in dB/µV in accordance with the CISPR 16 standard. Dos Reis Pontifícia Universidade Católica do Rio Grande do Sul Faculdade de Engenharia Departamento de Engenharia Elétrica Avenida Ipiranga, 6681 - Porto Alegre – RS CEP 90619-900 - Brasil Abstract - 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. ![]() Tool for Conducted EMI and Filter Design Elio Freitas Magnus, Júlio C. ![]()
