example is an [electronic ballast for fluorescent lamp].
|If we would
like to operate the ballast in the close loop,
†then we would need to know, (in order to design the feedback), the small signal transfer function between the frequency shift and the envelope changes at the output.
|The method of
envelope simulation was presented earlier, however, (for the sake of
I will go now over some basic elements.
|So that we
can get into the specific issues of the present study.
