In contrast with DC source, Fell cell has non linear characteristics that has lange voltage fluctuation due to load variation, and slow dynamic characteristics. when the loads are increase, the ripples of input and output voltage, also power densities, of inductor, capacitor, and switching devices, are bulky. This paper presents Interleaved boost converter using Fuel cell stacks proposed converter has merits to promote power densities without increasing loss. Because each converter has same switching frequency and constant phase difference. In this paper, Interleaved boost converter was design for 1[㎾], it's validity was proved by simulation and experiments.

This paper proposes a method correcting the error which is created inherently by time-step approximation in FEA. For a simple RL linear circuit, the error in time-step analysis is analytically investigated and the correction method is proposed. Then for a practical inductor model, non-linear time-step analysis is performed and the calculation result is corrected by the proposed method. The accuracy of the corrected result is confirmed by comparing the electric input and output power.

이 연구는 기계식 조향장치를 전동식 조향장치로 변환하는 주요 매개체인 전동기에 대한 설계에 관한 연구이다. 특히, 전동기가 가지고 있는 코깅토크와 토크리플의 저감 인자로 Pole/Slot 구조에 대하여 고려하였다. 저감인자에 대하여 2차원 유한요소해석을 이용하여 코깅토크와 토크리플을 비교 분석하였다.
