Performance and EMC analysis of an interleaved PFC boost converter topology

Abstract

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.

WSN Hardware for Automotive Applications: Preliminary Results for the Case of Public Transportation

“…However, despite the advantages, strengths, and promising findings of the proposed WSN architecture, it must be pointed out that the design and results are at a preliminary stage. Hence, one major limitation is that the automotive certification for the Raspberry Pi unit is not available at the moment, but some recent literature findings encourage the possibility to easily obtain it [19,23,46]. Furthermore, even though it has been demonstrated that the temperature, humidity, and bus vibrations do not affect the management of multimedia content, the data transmission in upload and download should be optimized and enhanced to avoid instabilities, since this is a primary requirement for the case company.…”
