[논문해석] Differential Power Processing for Increased Energy Production and Reliability of Photovoltaic Systems

1. 논문 원문 2. 논문 분석(0) Abstract요약—태양광 (PV) 시스템에서의 전통적인 에너지 변환 구조는 종종 변환 효율과 전력 생산 사이의 절충을 강요받습니다. 이 논문은 각 PV 요소가 최대 출력 점 (MPP)에서 동작하면서 생산된 총 전력의 일부만 처리하는 에너지 변환 접근 방식을 소개합니다. 이는 일련의 직렬 연결된 PV 요소의 MPP 전류의 불일치만 제공함으로써 달성됩니다. 차등 전력 처리는 전체 변환 효율을 높이고 부분 그림자, 손상, 제조 허용치 등으로 인해 발생하는 MPP 불일치와 관련된 문제를 극복합니다. 차등 전력 처리 구조는 몬테카를로 시뮬레이션과 함께 분석되고 비교됩니다. 차등 컨버터의 지역 제어는 분산 보호 및 모니터링을 가능하게 합니다. 신뢰성 분석은 전체 시스템 신뢰성..

[논문해석] Cascaded DC–DC Converter Connection of Photovoltaic Modules

1. 논문 원문+ 참고 논문 2. 논문 분석(0) AbstractNew residential scale photovoltaic (PV) arrays are commonly connected to the grid by a single dc–ac inverter con- nected to a series string of pv panels, or many small dc–ac inverters which connect one or two panels directly to the ac grid. This paper proposes an alternative topology of nonisolated per-panel dc–dc converters connected in series to create a hig..
