Re-submission ofquestion.                         Consider the full-bridge single-phase inverter with input voltageequal to 200V. This inverter is controlled by sinusoidal PWMtechnique with amplitude modu-     lationindex equal to 0.5 to generate a 3- level half-wave symmetrywaveform with frequency equal to 50Hz.                           e)Calculate the amplitude of fundamen-  talfrequency.                                                 f) Draw the waveforms of refrence and     carriersignals.                                               g) Obtain the waveform of outputvoltage.                                                         h)Design the trigger signals of switches.  Thanks foryour help.
