Power Losses in Switched Inductors: With insight & intuition..., (Paperback)

This 70-page handbook uses insight to explain how switched-inductor power supplies lose input power intended for the output. It discusses the significance of these losses in voltage regulators, battery chargers, and energy harvesters and the mechanics that govern them. The material explains and quantifies how resistances, diodes, transistors, and gate drivers consume ohmic, dead-time, i-v overlap, and gate-charge losses in continuous and discontinuous conduction. Concepts discussed include power-conversion efficiency, fractional losses, maximum-power point, the power theorem, reverse recovery, soft switching, and others. The handbook also shows how to use these concepts to design power switches and gate drivers and how losses ultimately alter, dominate, and peak conversion efficiency. Illustrative figures, equations, and examples complement discussions throughout.
