| Abstract: | Acoustic power amplifier is an important part of sonar transmitter. It is used to increase the output power and drive the transducer to launch sufficient energy acoustic signals into water. The impedance matching between underwater acoustic power amplifier and transducer include variable resistance matching and turning matching. The transducer resistance is transformed into a right value to make the power output voltage and current utilization supreme. This paper design a class AB underwater acoustic power amplifier, and complete impedance matching with a transducer. Its highest power is 170W. |
