• This chapter uses insight to explain how switched-inductor power supplies consume power that is otherwise intended for the output. It discusses the significance of these power 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 burn Ohmic, dead-time, i–v overlap, and gate-charge power in continuous and discontinuous conduction. Concepts discussed include power-conversion efficiency, fractional losses, maximum-power point, the power theorem, reverse recovery, soft switching, and so on. This chapter 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, examples, and SPICE simulations complement discussions throughout.
