This program analyzes the performance of the AC voltage regulator operating on the Sinusoidal pulse width modulation principle under different loading condidtions.

The inputs are:
- The input frequency.
- The modulation index.
- The phase angle of the load.
- The number of pulses per half period.

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 total harmonic distortion of the output voltage.
- The total harmonic distortion of the output current.
- The total harmonic distortion of the supply current.
- The input power factor.

Also are plotted, in figure No.1:
- The input supply voltage.
- The carrier signal,the modulating signal and The output voltage waveform.

In figure No.2 :
-The output voltage waveform.
-The output current waveform.
-The supply current waveform.
-The hamonic contents of the output voltage.
-The hamonic contents of the output current.
-The hamonic contents of the supply current.

To run this program:
-input the name of this programm 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 number of pulses per half period, for example 5.
