Design and Development of Neuro-Fuzzy based Multi-Level Inverter using FPGA

In the power electronic applications the power electronic converters represent its usefulness with the advance topology to drive the Grid. In this paper the multilevel inverters are designed with intelligent control techniques which given a precise output at the Grid. The paper proposes a three phase three-level inverter with advance Neuro-Fuzzy technique which is used to generate a constant voltage at the grid, connected a BLDC motor as a reference grid with the influence of FPGA PWM pulses to drive switches. The three phase three level inverter is designed with a six power switches, the AC output is given to BLDC motor, the speed is measured and compared with rated speed, the error signal is taken into an Neuro-Fuzzy controller, the output of controller is taken as a reference to generate PWM pulses from FPGA using Verilog programming to drive switches, the proposed modeled is simulated with ModelSim tool of MATLAB/Simulink environment
