Hi dear All
Thank you for reading my blogs.
I came back again ! ;-)
As i gave promise , i came back to continue about class D amplifier and SMPS !
See below , pictures , please :
Think about top photos !
Could you get my mean ?
If yes , good .
If no , no , don't worry !
The 1st , photo , is a three level SPWM ( the put put of two LM311 as a float out put !)
The message signal , is a sine wave when we want create SPWM ( sinusoidal pulse width modulation)
But here , it has a simple difference ! we have 2 identical sine wave , one of them is in phase , and the other , is out of phase ( 180 degree ) .
See the circuitry , please .
And about 2nd photo : you can see , what i did , exactly !
And about 3rd photo : those are the out put signals of each comparator .
Ok try to think about those photos , and what i want to say !
I'll come back with more things! stay tuned !
Wish you the best
Goldsmith
