Hello! I'm trying to generate a low power, high voltage sine wave that is unipolar (so, peak to peak ranges from 0V to 300V). Ideally, I would like the ability to vary the frequency from 10Hz to 60Hz. Is there an ideal method of doing this? With lower voltage I would generate my sine wave (bipolar), then use an op-amp to amplify it as desired, and also add a DC offset to make it unipolar... but I don't know of any op-amps that can handle the voltages I am interested in. I can easily make my sine wave at low voltage, then amplify it to -150V to 150V using a transformer... but can this be offset to 0V to 300V? or I can generate a low power 300V DC signal... but can I make a 0V to 300V sine wave out of this? Thanks for any advice!
