    I am a highly skilled professional with a Master's degree in Automatic Control and an Engineering degree in Electrical and Electronic Systems. My expertise includes designing and implementing various types of electric and electronic circuits, audio amplifiers, power converters, power supplies, and renewable energy systems. Additionally, I have extensive experience in designing ZVS quasi-resonant / LLC resonant power converters, maximum power point tracking systems, and SPWM, SVPWM three phases AC-AC inverters. Added to what mensionned before; I can design controllers (analog and didital) for complex systems (Current, voltage, toqrue, speed, pressure, temperature, flow .. etc). Experience: - Sensors, Power Electronics, Electric Machines (Motors/Generators) Structure and Command/Control. - Design and implementation of various types of audio amplifiers (Class AB, Class D, multilevel structure based). - Design of switch mode power supplies (SMPS), LLC resonant DC-DC converters, and quasi-resonant ZVS power converters. - Dimensioning and selection of components for Photovoltaic systems (Inverter, Batteries, Charger, PV panels, Cables, and Breakers). - Design and control of wind-turbine/hydro-turbine electric power generators, BLDC motor drives, DC motor drives, and induction motor drives (v/f constant, single-phase and three-phase). - Design and implementation of battery management systems (BMS), active balancers for batteries. - PV-based laptop supplies, solar grid-tie inverters. - Single/dual-axis sun tracking systems. - Active power factor correctors for reactive and non-linear electric loads (single-phase and three-phase). My broad background in automatic control and electronic systems makes me an ideal candidate for projects requiring experience in these areas. I am always eager to take on new challenges and continuously improve my skills and knowledge. Sample Projects: - Six-channel audio mixer with channel priority option. - Stereo/Mono Audio amplifier. - Ferrite and iron core transformers design. - High efficiency LLC resonant DC-DC converter. - Coil parameters meter (saturation current and inductance). - Flying Capacitor Multilevel power converter/inverter. - SPWM, SVPWM three-phase AC-AC inverter. - Controlled Active Rectifier (Sinusoidal current) - Off-Grid or Grid-tie renewable energy system (wind and solar power) . - Water/Air temperature control system. - Balancing using reaction wheel. - Three phase unity power factor rectifier. - Three phase/ Single phase active power factor corrector (Parallel active filter).
