Power converters design and analysis for high power piezoelectric ultrasonic transducers

摘要: High power piezoelectric ultrasonic transducers have been widely exploited in a variety of applications. The critical behaviour device is encapsulated its resonant frequencies because maximum transmission performance at these frequencies. Therefore electronic converters should be tuned those to transfer electrical mechanical efficiently. However, structural and environmental changes cause variations the which can degrade system performance. Hence, estimating within incorporated setup significantly improve This paper proposes an efficient frequency estimation approach maintain high applications using employed converter. Experimental validations indicate effectiveness proposed method.
