I have seen similar posts, but none of which seem to answer my questions/solve my issues.
I am trying to drive a 50W piezoelectric transducer (Cleaning transducer) to just simply get any constant output.
I brought the particular ones I'm using from here: https://www.allendale-ultrasonics.co.uk/ultrasonic-transducer-40khz.html
My thoughts so far have been to pulse the transducer at 40kHz using +18V on one side then -18V on the other (so total 36V then ground then 36V etc).
To do this I was going to use MOSFETs connected to a bench power supply and using a Microcontroller to provide the timing pulses (connected to gate of MOSFETs, via an amplifer(s) if needed).
Will this work?
My other idea was to use two sine waves out of phase with each other (180deg) across the transducer in a push-pull way using 2x30W power audio amplifiers.
Are these ideas along the right track?
Can anyone provide any insight on how to drive these correctly?
Thanks very much.
