I'm hoping someone on here may be able to help with a problem I have. Some background first:
I have been asked to run an experimant using a bipolar waveform at 500V peak to peak. To achieve this the signal from a signal generator was passed though an audio amplifier then through a small audio transformer. A basic set up I know but worked well for the application it was required for.
The problem:
I have now been asked to run a similar experiment using a unipolar square waveform of the following parameters
Vout - 60V-120V
Frequency - 50 Hz
Duty cycle 25%
I have a custom signal generator that can produce a maximum of 10V but if I put the unipolar signal through the original set up in comes out bipolar. I have been told this is because the audio amp does not have a 0V reference so cannot distinguish between bipolar and unipolar.
Does anyone out there know a way of amplifying the signal from the signal generator whilst still keeping it unipolar?
Thanks in anticipation of any answers.
