Seung‐Min Song, In-Dong Kim, Byunghwa Lee, Jeong-Min Lee · 2019
Generally transducers for active SONAR(SOund Navigation And Ranging)has large capacitive load characteristics. So an impedance matching circuit of high power transmitter is required to improve the power factor of transducer. Conventional matching circuits composed of L, C elements have many additional lumped elements. However, transducers for active sonar have many channels so that it is difficult to consist of many devices due to spatial limitations. Therefore, this paper proposes a new design method of transformer used in impedance matching circuit of transducers without any additional devices.
