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.

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

plzzzzzzzzzzz plzzzz can any body tells me the working of this pwm?

mohammed shelbayeh

you are the first in my eye,go my engineer,and i hope a beautiful future to you,
thank you eng.Yasin

Ahmad Al-Hoor

Thanks Eng.Shiboul

Lorenzo Luengo

really slow cause of bad programming :(

I understood some of this group of matlab applications but i there is alot more to understand (and as u told us "do not make any rating")
