인덕턴스의 정확한 계산은 인덕터 설계의 가장 기본적인 문제입니다. 본 논문에서는 먼저 유한요소해석(FEA)을 통해 코어형 인덕터의 코어 윈도우 및 권선에서의 코어 자속 밀도 분포와 누설 자속을 분석한다. 이를 기반으로 단상 코어형 인덕터에 대한 고정밀 자속 밀도 분포(iMEC)를 갖춘 향상된 자기 등가 회로를 제안합니다. 기하학적 구조에 따라 코어 창의 두 가지 누출 경로가 모델링됩니다. 또한 iMEC는 권선의 기자력을 해당 코어 분기로 나눕니다. 인덕턴스의 정확성을 향상시키기 위해 코어 자속 밀도 분포를 FEA 분포와 일치하게 만듭니다. iMEC에서 코어 레그의 자속 밀도는 5.6A의 FEA 시뮬레이션과 비교하여 150% 미만의 오류를 갖습니다. 인덕턴스의 최대 상대 오차는 8.5% 미만이며, 실제 프로토타입 테스트 데이터와 비교하면 평균 상대 오차는 6% 미만입니다. 동시에 iMEC의 높은 계산 효율성으로 인해 모집단 기반 최적화 설계에 매우 적합합니다.

Abstract: The accurate calculation of the inductance is the most basic problem of the inductor design. In this paper, the core flux density distribution and leakage flux in core window and winding of core-type inductor are analyzed by finite element analysis (FEA) firstly. Based on it, an improved magnetic equivalent circuit with high accuracy flux density distribution (iMEC) is proposed for a single-phase core-type inductor. Depend on the geometric structure, two leakage paths of the core window are modeled. Furthermore, the iMEC divides the magnetomotive force of the winding into the corresponding core branch. It makes the core flux density distribution consistent with the FEA distribution to improve the accuracy of the inductance. In the iMEC, flux density of the core leg has an error less than 5.6% compared to FEA simulation at 150A. The maximum relative error of the inductance is less than 8.5% and the average relative error is less than 6% compared to the physical prototype test data. At the same time, due to the high computational efficiency of iMEC, it is very suitable for the population-based optimization design.
