| Hi,
Does any one have experience with three level PWM using natural sampling and double-sided modulation ? If so, I would like to know the practical figures (I'v got theory and formulas ) of harmonics spectrum and sub-harmonic distortion and THD ? Any help would be appreciated .

| hello ZMH do u mean ( pritical figures) is the result of the spectrum analyzer output or .... i have some information about harmonic spectrum, THD, sub harmonic | |

| Hi , Ko Zaw Min Htut ,
I kindly share the one ,Tri-level PWM circuit . I got the some knowledge over this circuit . Base on this circuit , I implemented the prototype circuit to drive the Inductance device .I got the result ,I hope early. But , I still need to debug somethings . I hope so , this is the one you want .
I kindly upload as pdf format . http://www.zshare.net/download/515415815c044131/
regards, Nay Ni | |
