Neutral point clamped of string inverter / Bracewell Miga

This thesis presents the neutral point clamped type of inverter, converting from DC to AC, using pulse-width modulation (PWM) injection from PIC, sending the signal to optocoupler, followed by IGBT to trigger the function of open and close the gate. This project is designed for converting DC to AC voltage. Circuit designed and simulated on using PSIM simulation software. From this simulation, it could determine the output waveform for the voltage and current produced by the circuit. This circuit is then design in hardware to perform the real output produce by the real element of electronic component which then all the results recorded for analysis and comparison. Finally, the conclusion has been made regarding the results and objectives.
