14.4 Digital control of a current-mode synchronous buck converter.

Many advances have emerged since the second edition of this volume. This third edition explores the advent of LED drivers and DC-DC converters both for solar panels and for fuel cells. It covers converter power management, phase-shift PWM, and low-noise and bidirectional DC-DC converters, featuring a non-linear discrete model of the DC-DC converter itself. The text discusses new simulation tools such as PSIM, LTSPICE, and POWERESIM, and provides additional and updated information on digital control of DC-DC converters, switched capacitor converters, and power factor controllers.
