Journal ArticleDOI
Online calibration of MOSFET on-state resistance for precise current sensing
TL;DR: In this article, an approach for online current sensing calibration is presented where an auxiliary switch and a precision sense resistor are connected in parallel with a main power switch to achieve accuracy comparable to the sense resistor method, together with the advantage of essentially no additional power loss.
Journal ArticleDOI
Current-Limited Time-Optimal Response in Digitally Controlled DC–DC Converters
TL;DR: In this article, the authors address the problem of time-optimal load-transient response in digitally controlled dc-dc buck converters incorporating an inductor current limitation and derive the minimum number of switching actions required to handle a generic CL-TOC transient.
Proceedings ArticleDOI
Mixed-signal simulation of digitally controlled switching converters
TL;DR: Mixed-signal simulation models of a digitally controlled switching converter based on Matlab/Simulink and HDL/Spice simulation tools are presented and used in the design of a high-frequency digital controller integrated circuit for DC-DC switching converters.
Journal ArticleDOI
Fully digital hysteretic modulator for DC-DC switching converters
TL;DR: In this paper, the authors proposed an alternative modulation approach for digitally controlled DC-DC switching converters, which exploits the natural jittering activity of a digital hysteretic feedback loop in order to provide an effective increase in resolution.
Proceedings ArticleDOI
Online Health Monitoring in Digitally Controlled Power Converters
TL;DR: In this article, the authors focus on two aspects of power converter health monitoring: detecting and analyzing loss-related and frequency response-related changes, which can be implemented without any additional sensing points other than those required for operation of the converter and with minimal additional digital hardware.
