中文摘要:
      宽带大功率换能器是现代水声发展的一个重要方向,换能器与功放间的匹配也是其关键技术之一。文中从换能器负载阻抗复角与功放管耗散功率及电源供电效率的关系入手,结合窄带阵元串联或并联调谐方法的特点,确定了适合宽带阵元电匹配网络的电路形式。并针对研制的宽带换能器进行了大功率发射试验,取得了较为满意的结果。
英文摘要:
      Broadband high power transducers are important devices in modern underwater acoustics. M-atch between the transducer and the amplifier is a key in developing the broadband transducer. In this paper,relationships between load impedance phase angle,power amplifier dissipation and power supply efficiency are discussed. The matching methods based on serial and parallel resonance for a single frequ-ency transducer are studied. Electric matching circuits suitable for broadband transducer are designed. A test shows that the electric matching circuit is satisfactory for broadband high-power transducers.
