Abstract

전류원 배열 에너지 공급 시스템과 전류피드백 회로장치가 개시된다. 본 발명에 따른 전류원 배열 에너지 공급 시스템은 부하군의 일측에 출력전압을 공급하는 전압공급노드, 부하군의 다른 일측에 전류원을 연결하는 전압태핑노드, 전압공급노드와 연결되는 피드백 네트워크단, 전압태핑노드와 피드백 네트워크단 사이에 피드백라인으로 연결된 전류피드백단 및 전압태핑노드의 전압이 설정된 전압 이하인 경우 전류피드백단으로 전류가 흘러서 부하군에 공급하는 출력전압을 조절하는 DC전압조절기를 포함한다. 본 발명에 따르면, 부하군과 전류원 사이의 전압을 감지하여 필요로 하는 최소한의 전압을 안정적으로 공급할 수 있다는 효과가 있다.
