Performance and EMC analysis of an interleaved PFC boost converter topology

An extensive experimental analysis of a two-phase Interleaved PFC Boost converter (I-PFC-B) is presented in this paper. It aims to highlight the most important features of I-PFC-B operation, in terms of both performances and Electromagnetic Compatibility (EMC) issues. Therefore, several experimental tests are performed inside an anechoic RF chamber; in particular, Power Factor, Total Harmonic Distortion Factor, Current Crest Factor and energy efficiency are determined at different I-PFC-B output powers. Furthermore, appropriate Conducted and Radiated Emission tests are performed, in accordance with international standards, in order to reveal I-PFC-B aptitude as a non-intentional Electromagnetic Interference (EMI) source. The results highlight poor I-PFC-B performances at light loads, as well as potential conducted EMI issues within low and medium frequency ranges.
