Anyone has any experience with power amplifier design for electrostatic transducers?
I am using electrostatic transducers for transmitting ultrasound at between 40kHz to 80 kHz. However, these transducers requires high driving voltages around 100V peak and a bias voltage of 200V. I got a bias voltage from a DC-DC converter but am stuck with the power amplifier design. Basically it has to be high voltage and at the same time be able to match to the capacitive impedance of the transducer.
