The rise of ultrasonic system efficiency using miscellaneous adaptation schemes between electonic generator and piezoelectric transducer. Abstract. The paper makes an analysis of sundries adaptation schemes between electronic power generator, which has a commutation works, and piezoelectric transducer who generates ultrasonic field being feed by sinusoidal tension. The analysis allows the choice an optimum adaptation scheme by point of view of efficiency in condition of high power work - thousand watts. The work method consists to found the mathematical shape for adaptation scheme and traces the curves which characterize it operation in specific condition: rectangular input tension - sinusoidal output tension, on piezoelectric transducer. The piezoelectric transducer it is describes by it equivalent scheme The originality of this method consists in found a mathematical model, which characterize it working. This method was experimental verified. The method allows finding with promptitude the values of adaptation scheme for maximum efficiency and allows analyzing of influence for every component belonging of adaptation scheme.
