Biography

Dr. Shyam Akashe is a Professor in the Department of Electronics and Communication Engineering and Dean of International Cooperation \& Projects at ITM University, Gwalior, India. He received the M.Tech. degree in Electronics and Communication Engineering from Rajiv Gandhi Proudyogiki Vishwavidyalaya (RGPV), Bhopal, India, in 2006, and the Ph.D. degree from Thapar University (formerly Thapar Institute of Engineering and Technology), Patiala, Punjab, India, in 2013. His doctoral research focused on low-power memory cell design.

After joining ITM University, Gwalior, in 2012, he has been leading the M.Tech. program in VLSI Design as Program Coordinator. His research focuses on low-power VLSI design, device modeling, FinFET-based memory design, circuits for next-generation VLSI technologies, digital design, and FPGA implementation. He has authored over 300 peer-reviewed journal and conference publications and holds more than 10 patents in related areas.

Dr. Akashe received the Best Research Paper Award at the NSC-2005 held at IIT Bombay. His biographical profile was also published in Marquis’s Who’s Who in Engineering Field, USA, in 2015. He has served as a Technical Program Committee (TPC) member for several IEEE and Springer international conferences. He has also served as an editor for IEEE International Conference on Communication Networks (ICCN), IEEE International Conference on Communication Networks and Computing (CNC), Springer Information and Communication Technology for Competitive Strategies (ICTCS), and ICT Systems and Sustainability (ICT4SD). Currently, he serves as a Guest Editor for the journal Energies (MDPI), Special Issue on ``Energy Conversion and Storage Devices and Their Use in Electric Vehicles.''

EMI Filter Design and Analysis for an Isolated DC-DC Converter

As EV fast charging infrastructure has developed rapidly, electromagnetic compatibility (EMC) problems with DC-DC high-frequency converters have become more acute. In particular, multi-source multi-level active bridge (MS-ML-DAB) converters operating over a wide range of output voltages experience significant electromagnetic interference (EMI) due to rapid switching transitions and parasitic components. This study systematically analysed the electromagnetic interference (EMI) generated by the common mode (CM) and differential mode (DM) of the MS-ML-DAB converter for EV DC fast charging systems. A parasitic converter model is proposed to precisely identify the major noise processes in the EMI. Using FCC Class B emission-guided and impedance-based design concepts, the multi-stage EMI filter of the type π is analytically constructed for both input and output ports. The recommended filter shall provide impedance matching, adequate damping and stability in the event of significant voltage and current fluctuations. PSIM based simulations show significant noise abatement of DM and CM in the frequency range 150kHz to 30MHz in both working modes, confirming compliance with FCC Class B standards. This technique offers a practical and scalable solution to mitigate the EMF in high-power EV chargers.
