This program analyzes the performance of a voltage source inverter with Sinusoidal-pulse-modulated output, under different loading conditions.The inputs are:- The frequency of the output voltage waveform.- The modulation index.- The phase angle of the load.- The frequency of the carrier singnal.The outputs are:- The beginning, the end and the width of each output voltage pulse.- The rms Value of the output voltage.- The rms Value of the output voltage fundamental component.-The RMS value of the load current.-The RMS value of the supply current.- The Average value of the supply current.- The total harmonic distortion of the output voltage.- The total harmonic distortion of the output current.Also are plotted, in figure No.1:- The carrier and modulating signals.- The output voltage waveform.In figure No.2 :-The output voltage waveform.-The output current waveform.-The supply current waveform.-The harmonic contents of the output voltage.-The harmonic contents of the output current.-The harmonic contents and the average value of the supply current.To run this program:-input the name of this program, ?invspwm?, from the command window.-enter the required quantities: frequency, for example 50 or 60. modulation index, less than 1, for example 0.7 , phase angle of the load in degrees, for example 45, The frequency of the carrier signal, for example 1000.
