PostSubject: PWM   Thu Oct 26, 2006 6:03 pm

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 .

ZMH

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

really pls share ur data then...
cos now i am using Agilent Signal Generator for 10MHz system bandwidth generation to use in baseband synthesizer. i want to reduce THD till <.2 is it possible or ?

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 .
