20khz Ultrasonic Generator Circuit Diagram. A couple of the buffers u1a and u1b can be seen attached within a variable frequency astable oscillator circuit having a 50 duty cycle square wave output. The 45 khz carrier is frequency modulated by a modified trapizoidal voltage waveform applied to pin 5 of the 555 timer.
The circuit is simply a 555 timer ic connected as a squarewave generator. The high frequency electrical energy is converted by the transducer is again converted into a mechanical movement of the same frequency followed by the mechanical motion transmitted to the weld head through a set can. Ultrasonic generator circuit also named ultrasonic transducer driver circuit or ultrasonic cleaner power driver board.
Ultrasonic generator circuit also named ultrasonic transducer driver circuit or ultrasonic cleaner power driver board.
2 makes use of 6 buffer gates of a solitary 4049 cmos inverting buffer ic. It provides an ultrasonic frequency to drive the ultrasonic transducers inside ultrasonic cleaners. The frequency is 20khz 25khz 28khz 33khz 40khz 60khz 70khz 100khz. The principle of ultrasonic welding by the ultrasonic generator 50 60 hz current is converted into 15 20 30 or 40 khz energy.
