为了减小水声功率发射机的能源消耗,提高工作效率,用较小功耗的晶体管发射较大功率,采用晶体管D类功率放大器较为理想。实际应用中巳得到了充分的证明。本文以实用电路为例介绍了电路基本特点和调试方法。
In order to reduce the energy consumption of the hydro-acoustic power transmitter and improve the working efficiency, the larger power is transmitted by the smaller power-consumption transistor, and the transistor type D power amplifier is preferable. Practical applications have been fully proved. This article takes the practical circuit as an example to introduce the basic characteristics of the circuit and the debugging method.
