Abstract

In this paper, we propose a method for high-frequency modeling of transformers using the S-parameter. The open and short circuits of the primary and secondary sides were configured, and the reflection coefficient in each circuit was measured using a vector network analyzer. The equivalent circuit elements were extracted from the measured results to model the high-frequency equivalent circuit, and the validity of the method was verified by comparing the measured S-parameters in a 2-port network with the simulation results.

본 연구는 S-parameter를 이용한 변압기의 고주파 모델링 방법을 제시한다. 1차측과 2차측을 단락 또는 개방 회로를 구성하여 각 상태에서의 반사계수를 Vector Network Analyzer로 측정하였다. 측정 결과로부터 등가회로 소자를 추출하여 고주파 등가회로를 모델링하고, 2-port 회로에서 측정한 S-parameter 측정치와 시뮬레이션 결과를 비교함으로써 타당성을 검증하였다. 이는 정확하고 예측 가능한 고주파 변압기를 설계하는데 적용될 수 있다.
