0. 원문 1. 내용 (0) Abstract This paper introduces a novel approach for dynamically detecting the lowest speed threshold at which regenerative braking is effective in electric vehicles (EVs). The control approach is based on real-time sensing of the motor controller dc link current and disabling regenerative braking when current changes direction while the motor is operating as a generator. Various ..

0. 원문 1. 내용(0) AbstractThis paper proposes a simple but effective method of electric brake with energy regeneration for a brushless dc motor of an electric vehicle (EV).During the braking period, the proposed method only changes the switching sequence of the inverter to control the inverse torque so that the braking energy will return to the battery. Compared with the presented methods, the prop..

Abstract 이 논문은 전해 커패시터가 한상 사용되는 에너지 버퍼링 응용 분야, 특히 단상 교류와 직류 사이의 버퍼링에 대한 것입니다. 이러한 커패시터는 필름 및 세라믹 커패시터와 비교하여 높은 에너지 밀도를 가지지만 수명이 제한되고 신뢰성이 주요 관심사입니다. 이 논문은 전해 커패시터 없이도 비교 가능한 유효한 에너지 밀도를 달성하면서 이러한 제한을 극복하는 쌓인 스위칭 커패시터(SSC) 에너지 버퍼 아키텍처와 그 일부 토폴로지를 제시합니다. 아키텍처 접근 방식과 함께 설계 및 제어 기술도 소개됩니다. 320 V 직류 버스에 맞추어 설계된 필름 커패시터를 사용한 프로토타입 SSC 에너지 버퍼가 구축되었으며, 135 W의 부하를 지원할 수 있도록 설계되었습니다. 이 ..
