I want to drive piezoelectric transducer with resonant frequency 110khz and input voltage 70 volts ac with arduino. I generated a square wave of same frequency with arduino than converted it into ac voltage using RC filter than for the step up I used transformer small getting amplitude of 67 volts peak to peak. When I connect piezo to transformer the amplitude falls to 2 volts. The piezo is not working.
Is there any other way to drive this piezo?

Thanks in Adavance

And what is the capacitance of the transducer?

Starting with the Arduino and filtering and transformer when all is said and done I doubt you have even close to the needed power to drive the transducer.
