中文摘要：
介绍了一种用于石油仪器的大功率多极子阵列声波换能器激励源的设计方案。该方案中，大规模复杂可编程器件执行DSP通过专用串行线路发送的命令，精确地控制多个激励源的激励时刻和激励宽度，实现了对声波辐射能量的最佳控制。对该方案进行了实验测试。测试结果表明，所设计的激励源能够保证控制电路系统在150℃环境温度下稳定工作，适于井下高温高压恶劣环境应用。
英文摘要：
A kind of downhole muhipole acoustic transducer transmitter with high power that is applied to petroleum tools was introduced. The command which is sent out by digital signal processor via special serial bus is carried out by complex programmable logic device（CPLD）, and fire time and fire width of multi-transmitters are also accurately controlled by CPLD, which can control acoustic radiation energy optimally. The test results show that the control electronic system can work stably at 150 ℃. This shows the transmitter is applicable to high temperature and high-pressure working condition of downhole.
