High frequency ultrasonic generators and amplifiers<\/h2>\n

\ud83d\udd39What are the limitations of linear amplifiers?<\/i><\/strong><\/h2>\n

The production of high-frequency power ultrasound typically relies on electronic techniques derived from radiofrequency linear amplifiers.<\/p>\n

Their main drawbacks include efficiency, size, weight, and a limited ability<\/strong> to adapt to a load composed of piezoelectric transducers.<\/p>\n

They do not allow the control of the power delivered to the transducer or adaptation to its behavior based on changes in environmental parameters (temperature, pressure, medium, etc.).<\/p>\n

The new generation of digital amplifiers provides an effective solution to the previous limitations. This innovation will be presented by our colleague at the JSUP 2023<\/strong> conference.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=”.vc_custom_1701168289374{margin-bottom: 0px !important;}”]Thanks to the integration of a FPGA<\/strong> technology, our system allows to:<\/p>\n

    \n
  • Generating and controlling ultrasound up to 5 MHz<\/strong><\/li>\n
  • Simultaneously acquiring real-time data<\/strong><\/li>\n

The application involves controlling the emission beam on an 8-element transducer <\/strong>to create very high acoustic pressure at the focal point, ensuring cavitation. Successfully tested in a water tank, the generator provides remarkable results with different durations, amplitudes and focal positions.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=”.vc_custom_1701168833247{margin-bottom: 0px !important;}”]\n
