Control oriented modeling of DCDC converters

Resonant Converters : Topologies , Dynamic Modeling and Control

Recent interest in high frequency resonant converters has prompted this exploration of aspects that have not previously been studied carefully. More specifically, this thesis examines possible methods for deriving resonant converter topologies and show how to develop dynamic models for converter behavior, demonstrates the design and implementation of control schemes based on these models. Syste...

Modeling of cascade buck converters

In this paper signal flow graph non-linear modeling of cascade buck converters is presented. Unified signal flow graph model of the converter is developed and then deduction of large, small-signal and steadystate models from the unified graph is demonstrated. Converter performance expressions are derived. Largesignal model is developed and programmed in TUTSIM simulator. Large-signal responses ...

Control of DC-DC Converters

A constant voltage regulator, to supply constant power loads, is realized using a Switched-capacitor converter. Exhaustive studies have been carried out to find the suitability of available control schemes and finally one control scheme investigated with (i) operation of the converter at different crossover frequencies (ii) operation of the converter at different phase Margins. Various operatin...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
