Ultrasonic transducers are used for several applications on boats. Alas, I haven't seen any tuned for exactly 1.5 MHz, but perhaps a transducer tuned to some slightly different higher or lower frequency …

Oct 10, 2012 · 14 My project needs to drive a medium power ultrasonic piezoelectric transducer from a sine wave (/ sawtooth) sweep generator that sweeps +/- 2% of the transducer resonant frequency. …

Mar 29, 2017 · 2 Here is the ultrasonic generator circuit I'm trying to understand: It is powered by USB and it produces 100V at 100kHz on the piezoelectric speaker BQ1. Two mutually inverted PWM …

I designed an inverter to use an ultrasonic generator for an ultrasonic homogenizer. The problem is that even at low current, the switches get abnormally hot (specially two of them Q3 and Q4): swit...
