Generally, transducers for active sound navigation and ranging (SONAR) has a low power factor due to large capacitive load characteristics. Thus, high-power transmitter requires an impedance matching circuit to improve the low-power factor of a transducer. Conventional matching circuits composed of L and C elements have many additional lumped elements. In addition, transducers for active sonar have numerous channels. As a result, the implementation of the matching circuit with many devices is non-practical and bulky due to spatial limitations. Therefore, this paper proposes a new matching circuit that uses the magnetization inductance of the transformer without additional elements. In addition, a design method of a transformer that implements a matching circuit using magnetization inductance is proposed. The proposed matching circuit is verified by the experimental results, and the volume and weight are reduced by approximately 20% compared to the conventional matching circuit.

有源声纳大功率发射机匹配电路变压器设计

通常，由于大电容负载特性，用于主动声音导航和测距 (SONAR) 的换能器具有低功率因数。因此，大功率变送器需要阻抗匹配电路来改善换能器的低功率因数。由 L 和 C 元件组成的常规匹配电路具有许多附加的集总元件。此外，有源声纳的换能器有许多通道。结果，由于空间限制，具有许多设备的匹配电路的实现是不实用且庞大的。因此，本文提出了一种新的匹配电路，该电路利用变压器的磁化电感，无需附加元件。此外，提出了一种利用磁化电感实现匹配电路的变压器设计方法。
