Hi All,
I am interested in making an generator for
high power (50-100W) industrial ultrasonic transducers.
I believe the capacitive load is 5200pf, Vpp ~220V.
Freq : 28Khz (squarewave)
In intend to generate the 28kHz with a microproc (AVR?)

I read that one can drive this with hi-freq step-up transformer.
I have no knowledge on high-power/hi-freq transformer
design as may be required for this application.

I know one can buy self-osc generator scheap-cheap from China.

I would like to make my own though.

Regards,
GjL
