This program analyzes the performance of the AC voltage regulator operating on the uniform 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 and the modulation index.
- 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.
