    (Université M’Hamed BOUGARA de Boumerdes : Institut de génie electrique et electronique (IGEE), 2016) Khenfer, Zoubir; METIDJI, B. (supervisor)
    Power electronics is the technology associated with efficient conversion, control and conditioning of electric power from its available input in to the desired electrical output form. The actual work falls into this scope presenting an FPGA based control and implementation of three levels voltage NPC inverter. The Multi-Carrier Sinusoidal Pulse Width Modulation (MC-SPWM) is the control method adopted in order to digitize power so that a sequence of voltage pulses can be generated by the on and off of the power switches. writing a VHDL code of the adopted modulation technique ,checking the code on MODELSIM software then loading the code to the FPGA kit through QUARTUS environment are the carried steps in order to end up with the right switching signals. The design and implementation of the appropriate gate drive circuitry is a the next step in order to assure a suitable driving circuit that is required to supply the necessary charge to the power valves gates . Using this control method and the gate driving circuitry along with the specified topology of the three levels NPC inverter leads to the desired results of this works. Results that are presented and discussed.
