Study on Highly Reliable Transmitter Applicable to Hydroacoustic Data Transfer

XU Xiang bin (Dept. of Elect.Engin.,Xiamen Univ.,Xiamen 361005, China)  
In order to convert electronic signal to acoustic wave, then transmit it under the sea water, it is obviously very important to develop a kind of highly reliable hydroacoustic transmitter. The reliability problems of the high power hydroacoustic transmitter are proposed through the study on the traditional push pull circuit using pulse signal to drive reactance load. Some improved measures are put forward to avoid damage to the power devices under idling or single side stimulus condition. With the improvements, the high reliability of the transmitter is confirmed by long term experiments on the sea and the performance of the system is greatly improved. Furthermore, these practical measures are of great value to improve the performance of power devices under the condition of PWM stimulus and reactance loads.
