Session 12 overview: Inductor-based power conversion: Analog subcommittee

High-efficiency inductor-based DC-DC converters are now ubiquitous in the electronic world, while wireless power transfer techniques, often based on inductive coupling, are gaining importance. Trends in inductive power conversion include higher switching frequencies, granular power delivery and support for multiple voltage domains, techniques leading to high efficiency over wide ranges of operating conditions, as well as approaches to integration of power management functions. Various solutions are required to effectively match source and load requirements in diverse applications. This session begins with three papers addressing control techniques for DC-DC power converters, followed by three papers that describe approaches to generating multiple outputs using a single inductor. The last part of the session is dedicated to circuits for inductive wireless power transmission. A highly integrated system and several techniques to increase the power transmission efficiency against the distance and load variations are shown.
