Ph.D. Thesis on Fractional Order Power Converters

The University of Technology awarded a Ph.D. degree to Mr. Mohammed Omar Ali for his thesis:
“Modeling, Simulation, Analysis, and Implementation of Fractional Order Regulated Electric Power Converters.”

The thesis explored various DC-DC converter designs for voltage regulation. The research focused on:

  1. Analyzing isolated DC-DC converters, specifically the Single-Ended Primary-Inductor Converter (SEPIC), for wide input voltage ranges (60–90V) and regulated output voltage (up to 315V).
  2. Proposing new multi-level inverters with seven and nine levels, using advanced modulation techniques for improved harmonic distortion reduction.

The researcher employed MATLAB/SIMULINK for modeling and achieved a SEPIC efficiency of 83.42% at a 65V input. Practical implementations confirmed the efficacy of the proposed designs.
