Summary: “The book provides a comprehensive overview of Single-Inductor Multiple-Output
Converters from both theoretical and practical perspectives. Based on the authors’ in-depth research,
the volume covers not only conventional SIMO DC-DC converters but also the new generations of
SIMO such as SIMO AC-DC converters, SIMO DC-AC converters, and the latest SIMO hybrid con-
verters”—Provided by publisher.
