| Abstract |
Piezoelectric ceramic materials are of main interest in the field of atomization applications, in order to generate microscopic droplets, which are difficult to obtain by mechanical systems. In this work an excitation electronic system for piezoelectric transducers is presented. The system is oriented to piezoelectric device characterization with resonance frequencies up to 2MHz and is based on a full bridge DC – AC voltage converter implemented with power VDMOS transistors. The technical solutions adopted to design and fabricate the system, as well as the main electrical characteristics in operation conditions are discussed in detail. The system allowed the measurement of droplet diameter distribution using a laser difractometer. The most relevant results concerning a typical PZT transducer during atomization operation are also shown. Contributions to piezoelectric transducer modeling and simulation are also proposed. |
