Haruo Kobayashi (SMIEEE)

Gunma University, Japan

Biography: Haruo Kobayashi received the B.S. and M.S. degrees in information physics from University of Tokyo in 1980 and 1982 respectively, the M.S. degree in electrical engineering from University of California, Los Angeles (UCLA) in 1989, and the Ph. D. degree in electrical engineering from Waseda University in 1995. He joined Yokogawa Electric Corp. Tokyo, Japan in 1982, and was engaged in research and development related to measuring instruments and mini-supercomputer. In 1997, he joined Gunma University as an Associate Professor and promoted to a Full Professor in Division of Electronics and Informatics. Currently he is Professor Emeritus there. His research interests include mixed-signal integrated circuit design & testing, and signal processing algorithms. He has published more than 160 journal papers and 450 international conference papers. Also, he has supervised 20 Ph. D. students and 160 M. S. students. He received the Yokoyama Award in Science and Technology in 2003. He is a Senior Member of IEEE, IEICE and IEEJ.
Speech Title: Exclusive Control for Single-Inductor Double-Output DC-DC Converters
Abstract: This presentation will introduce Single-Inductor Double-Output (SIDO) DC-DC converters, highlighting our proposed exclusive control methods, which integrate PWM control, ripple control, hysteretic control, or soft-switching techniques together. In this system, only the sub-converter with the larger output error is selected, and the inductor current is supplied exclusively to the selected sub-converter from the power stage for the entire period. The transient response can be faster, and the output ripples can be smaller. Additionally, they don’t require current sensors, and their circuits are relatively simple. Their configuration, operation, simulation results, and experimental findings will be presented.
