Title Proper : DIGITAL CURRENT MODE CONTROL OF DC-DC CONVERTERS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Digital current mode control of DC-DC converters combines advantages of currentmode control, including overload current protection and robust dynamics, and advantages ofdigital implementation, such as programmability, flexibility, and scalability. To make digitalcurrent mode control practical, this thesis attempts to address several issues: quantization andlimit cycling, current sensing and resolution of current analog-to-digital (AID) converters,digital current mode control algorithms, and implementation of overload current protection.In the study of quantization and limit cycling issues, we derive static and dynamic systemmodels with quantizers, which help understanding of how to avoid undesirable oscillationsknown as limit cycling. A digital current mode control architecture and a control method areintroduced to enable system realization using low-resolution current sensing. For currentsensing, we propose a differential delay-line AID converter...tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
