University of Toronto

Laboratory for Power Management and Integrated Switch-Mode Power Supplies

Research Areas

Multi-disciplinary resarch program of our group is in general area of power managment. It combines power electronics, mixed-signal IC design, control, digital signal processing, magnetics design, and packaging. The applications range from very low-power systems for mobile applicatons and implantable medical devices, consuming power from a fraction of milliwatt to several watts, to power processing systems for automotive applicatons and green buildings consuming up to few killowatts of power. Several of our research streams are listed below and more information about our research you can obtain through our publications or by contacing us.
