Studies on Current Hysteresis Controllers and Low Order Harmonic Suppression Techniques for IM Drives with Dodecagoal Voltage Space Vectors
(2017-12-01)
Multilevel inverters are very popular for medium and high-voltage induction motor (IM) drive applications. They have superior performance compared to 2-level inverters such as reduced harmonic content in output voltage and ...
Ballast-Free Variable-Speed Generation for Standalone and Grid-Connected Micro-Hydel Power Plants
(2017-12-12)
Concerns about climate change brought about by the increasing usage of fossil fuels has made it imperative to develop sustainable energy usage based on renewable sources. Micro-hydel plants are an important source of ...
Composite Current Space Vector Based Powerline Communication (PLC) Method For Grid Connected Inverters In AC Microgrids
(2017-05-25)
Power distribution facilities all over the world have been committed towards making the grids smarter in order to reduce the risks of grid failures and provide an affordable, reliable, and sustainable supply of electricity ...
Reactive Power Planning And Operation of Power Systems with Wind Farms for Voltage Stability Improvement
(2017-09-23)
In recent years, the electric power industry around the world is changing continuously due to transformation from regulated market structure to deregulated market structure. The main aim of the transformation of electric ...
Spectral And Temporal Zero-Crossings-Based Signal Analysis
(2017-09-20)
We consider real zero-crossing analysis of the real/imaginary parts of the spectrum, namely, spectral zero-crossings (SZCs). The two major contributions are to show that: (i) SZCs provide enable temporal localization of ...
Loss Ratios of Different Scheduling Policies for Firm Real-time System : Analysis and Comparisons
(2017-11-27)
Firm real time system with Poisson arrival process, iid exponential service times and iid deadlines till the end of service of a job, operated under the First Come First Served (FCFS) scheduling policy is well studied. In ...
DSA Image Registration And Respiratory Motion Tracking Using Probabilistic Graphical Models
(2017-10-18)
This thesis addresses three problems related to image registration, prediction and tracking, applied to Angiography and Oncology. For image analysis, various probabilistic models have been employed to characterize the image ...
Analysis of Local Field Potential and Gamma Rhythm Using Matching Pursuit Algorithm
(2017-11-17)
Signals recorded from the brain often show rhythmic patterns at different frequencies, which are tightly coupled to the external stimuli as well as the internal state of the subject. These signals also have transient ...
Design And Control of Power Converters for Renewable Energy Systems
(2017-09-20)
Renewable energy sources normally require power converters to convert their energy into standardized regulated ac output. The motivation for this thesis is to design and control power converters for renewable energy ...
Coupling Of Electromagnetic Fields From Intentional High Power Electromagnetic Sources With A Buried Cable And An Airborne Vehicle In Flight
(2017-05-23)
Society’s dependence on electronic and electrical systems has increased rapidly over the past few decades, and people are relying more and more on these gadgets in their daily life because of the efficiency in operation ...
