Abstract: High power density DC-DC converters utilize interesting interleaving techniques together with novel magnetic devices and wide bandgap semiconductors to improve the size and volume of the power electronic system onboard electric vehicles. Interleaving strategies commonly exploit the common mode voltage in combination with magnetic coupling to naturally increase and mitigate the ripple frequency, while the new semiconductor and magnetic materials may significantly aid to reduce the converter size by allowing switching frequency increase and improved magnetic integration and construction. This webinar presents a brief review on high power density DC-DC converters for electromobility applications showing how medium power converters have been improved in gravimetric density during the last years in search of a more efficient and reliable electromobility.

Ismael Araujo-Vargas (M’02) received the B.Sc. degree in communications and electronics engineering from the Instituto Politécnico Nacional of Mexico (IPN), Mexico City, Mexico, in 1999, the M.Sc. degree in power electronics and drives from the Universities of Birmingham and Nottingham (joint degree), Birmingham U.K., in 2001, and the Ph.D. degree in electrical and electronic engineering from the University of Manchester, Manchester, U.K., in 2007. Since 2001, he has been a Lecturer of power electronics with the Escuela Superior de Ingeniería Mecánica y Eléctrica, ESIME Culhuacan, IPN, Mexico City, Mexico, where he obtained recognition in 2008 to be with the Postgraduate and Research Studies Section of ESIME Culhuacan. From 2010 to 2012, he coordinated a research project on power quality issues for the Metropolitan Underground System of Mexico City, STC Metro, from which he established the Electric Power Conversion and Quality Research Laboratory (LINC 2 E 2 or LYNX) of the IPN. Since 2016, he has been leading research projects on high power density electronics for electric vehicles. His research interests include high-power factor rectifiers, multilevel inverters, DC–DC converters, and modeling and control of power electronic systems for more-electric transportation systems. Dr. Araujo-Vargas has participated in several journal and conference papers, and as a regular Reviewer of the IEEE Transactions in Power Electronics, IEEE Journal of Emerging and Selected Topics on Power Electronics and IEEE Transactions on Industry Applications and their respective conferences.
