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.

Thanks for this program.
just executed your code in Matlab and received the error at line 107:
??? Error using ==> minus
Matrix dimensions must agree.
Error in ==> invspwm at 107
[alpha' beta' (beta-alpha)']
have others experienced this problem?
just as it. works!
RESPECTFULLY REQUESTED TO PROVIDE THIS AS
i am interested to have the full information
im writing to you about if you can help me to design current source inveretr single phase or 3 phase
do take care
i want to know more about the VSI.
Thanks. This what I was looking for.
a good approach to solve, which i require
i want the matlab based inverter
i need harmonics analysis. Please someone contact me.
if anyone have used this source code, please do contact me
I hope this will help me .
This is a good piece of work
Chas Cramer from St. Marks?
Hi, I am studying electrical engineering and I try to model a PWM converter using controlled voltage sources. Does anyone have some details about that.
Thank you in advance.
very nice program....
good, you must add some more performance indices like effect of change of firing angle of scr, space vector pwm and other pwm technique
this program assist me for calculate and analyse efek of harmonic output voltage in inverter
i want some details about inverter design using matlab please send the details
This is what I was looking for, thank
i want to down load this file
