So why even bother with a sin wave anyway because the h bridge will turn that back into a square wave so you might just as well have a square wave driving your bridge.
Well I need a pwm signal to drive my h bridge. The output of my H bridge will be filterd in order to generate a sine wave. The 3 sine waves will control a 3 phase motor.
So now you know what I mean
So as I asked before is it possible to vary the frequency of the sine waves in a better way than the index items ??
Thanks in advance
