초록

수중용 전기 음향 변환기용 외부 회로를 구성할 때, 파워 앰프의 내부저항이 매우 작은 경우 정합 회로를 구성하기 보다는 부하측의 역률을 개선하는 것을 선호 한다. 기존 연구의 결과를 살펴보면 광대역에서 최대 파워를 전달하게 하는 정합회로를 구하는 방법을 많이 연구되어 왔으나, 두 개의 공진점을 갖는 수중용 광대역 전기 음향 변화기에 적용할 만한 광대역 역률 개선 튜닝 회로를 구성하는 방법은 논문화된 결과는 드물다. 본 논문에서는 기존의 정합회로 설계에서 사용하는 체비세프 설계법을 기본으로 하여, 좀 더 낫은 결과를 가질 수 있도록 하는 복합 최적화 과정을 바탕으로 역률 개선 회로를 설계하고 이를 실험을 통하여 역율 개선을 확인한다.

In the design of underwater electro acoustic transducer, power factor improvement circuit is more required rather than impedance matching if the driving power amplifier has little inner resistance. Many research results have been focused on the power matching circuit designing for transferring maximum power in the wideband. There are few results in the designing study on the power factor improvement for the wide band underwater electro acoustic transducer. In this paper, we set up a new design method on the power factor improvement for the wide band electro acoustic transducer, and confirm its feasibility by the experiments.
