this is indeed svpwm. the triangle (0-Ts) is used to switch comparing with the tgx, which is the amount of time to spend at each state, not the sinewave. otherwise it would be comparing the sine input directly with the triangle after normalization with Vdc.

nice program, but I dont think you can call this a SVPWM. You are generating the firing pulses of the transistors through a sinusoidal modulation, therefore it is not SVPWM. For example:

%% generation of switching function SA SB SC
if tgx(1,i)>= Vtri(i)

Feel free to discuss.

Please is there a way I can get an m-file on a 9 phase or multilevel SVPWM.
Please kindly assist me by sending it to
Thanks in advance

I need two induction motor (three phase) with an inverter with a 5 phase control which works on DTC method. Can you please to send any related matlab file to my email address:

nice program

Why there are no even harmonics in load voltage for even multiples of load frequency(i.e. 33*50,35*50,etc)??

rohit chandan, could you please share with me algorithm for 3-level inverter?



i have gone through your program and i have doubt on some parts of the program so could you please explain the program.u can share with me in

Hi, can you share with me the file embedded matlab for card DSP.


wer do

it is you know how to implement svpwm for diode clamped 3-level inverter?normally people always used 2-level. no such example for 3-level..the sector and vector identification is quite hard. hoping to get information on this

i used this m-file for with IM m-code but executing a m-code takes more time compare to simulink model on my pc..
try to use below simulink model , it has same algorithm..
if you want to use this code with IM m-code you can do.. you can use machine code below..


How to use this code to run an IM??


rohit chandan

@peppa yeah this SVM is working fine for vector control of IM, i have already checked..


really good..
keep up the good work..
do you have simulation of vector control that use this svpwm?

rohit chandan

cycle=3; %% no of cycle of modulating wave
ts=0:Ts/100:cycle/fmod; %% step time
