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.

An inductor modeling suitable for DC-DC converters is proposed in this paper. It consists of introducing an appropriate parallel resistance in order to account for inductor current ripple when averaging technique is employed. This allows the development of an improved averaged model for DC-DC converters, which takes into account inductor power losses due to current ripple phenomenon. The worth and effectiveness of the proposed modeling approach has been validated through a simulation study, which is performed in the Matlab-Simulink environment and refers to the case of a boost DC-DC converter.
