- Development and simulation of power electronics converters using Psim
- Design of schematics: Soft-start board, PFC, Isolated DC/DC using Altium Designer
- Design of PCB using Altium Designer
2010 - 2010- Design of an electrical conversion chain for railways applications
- Use of multilevel converters to improve the quality of energy:
• Enhancement of the transmission capacity
• Improvement of the power rate and reduction of the THD
- Use of space vector modulation in order to control the converters:
• Quicker control response and lower switching frequency
• Smaller THD than Pulse Width Modulation
2009 - 2009- Design of electronic components for a Matlab Simulink library:
• PWM generation including dead times control
• Measuring devices for converters and control methods
- Comparison of the Simscape library and the Simulink library:
• Computing times and accuracy of results
• Model-based design programming
