Switched Inductors: Control Loops: With insight & intuition
₱770.00
This 48-page handbook uses insight to show how feedback loops switch and control switched-inductor dc-dc power supplies. It explains how pulse-width-modulator (PWM), hysteretic, and constant-time peak/valley loops switch the inductor, offset the current or voltage they control, and respond to fast input or output variations. It also illustrates how summing comparators can absorb the functionality of error amplifiers and remove the loading effect normally present in current-mode voltage loops. The handbook ends with compact, fast, and low-cost resistive, filtered, and voltage-mode voltage-looped (voltage-squared) bucks. Along the way, the material introduces and reviews comparators, hysteretic comparators, summing comparators, pulse-width modulators, SR flip flops, pulse generators, sub-harmonic oscillations, and slope compensation. Design notes and illustrative figures, equations, and examples complement discussions throughout.
