Hi,
I have powerfull ultrasonic tranducers for 20kh to 80kh, need to build driver board
can we use 555 timer to drive it?

how the high excitation produced to drive it?
I am attaching two schematics from net, kindly help me in building the driver

excitation voltage:1000 V
Frequency (KHz) 30
Resonance Impedance (Ω) 10-25
Static Capacity (pF)±10% 5000
Input Power (W) 100

Best to use a Pushpull out with a transformer, the transformer is tuned to your centre frequency.

Any gain mis match will cause the 2 amplifiers to work against each other to some fraction of the total power.

The high power ultrasonic systems I was involved with used total loop phase sensitive feedback so it settled on the resonant frequency of the transducer. The TS stated a transducer capable of a wide frequency range - I have no experience catering for one like that.
