Task 1 Based on your chosen values of both input voltage sources and load power, determine the electrical ratings of all the switches and show them in tabular form.
Task 2 Implement Phase Shifted Carrier Based PWM (PSCPWM) for the 5-level, 7-level and 9-level inverter, obtain the output voltage waveform at each stage and then resultant voltage waveform. Do not forget to include the waveforms of each gate pulse. Perform FFT analysis on the Simulink and determine Total Harmonic Distortion (THD) of the voltage.
Task 3 Implement Level Shifted Carrier Based PWM (LSCPWM) for the 5-level, 7- level and 9-level inverter, obtain the output voltage waveform at each stage and then resultant voltage waveform. Do not forget to include the waveforms of each gate pulse. Perform FFT analysis on the Simulink and determine Total Harmonic Distortion (THD) of the voltage.
Task 4 Connect a resistive load and obtain the waveforms of output voltage and output current.
Task 5 Connect an RL load and obtain the waveforms of output voltage and output current.
