Abstract

Recent trends in active sonar design have called for large increases in the acoustic power output of sonar transducers. This paper discusses the impact of these trends on the power requirements of the electronics to drive the transducers. The effects of taking large power pulses from the supply are discussed and solutions to the consequential problems are outlined, for a variety of different systems. The application of various amplifier configurations and control techniques are examined in relation to the problems of matching the output of the power amplifier to the input of the sonar transducer. This is further expanded to consider the drive requirements of both magnetostriction and ceramic (PZT) transducers. Finally, the paper gives an example of the relationship between the required acoustic power and the rating of the power amplifier showing why apparently overrated amplifier power outputs are necessary.
