Zusammenfassung:The present invention relates to an energy harvesting apparatus which uses a direct current energy harvesting energy source and an alternating current energy harvesting energy source and a method thereof. The energy harvesting apparatus comprises: an alternating current harvesting unit extracting electricity from an alternating current environment energy source; a direct current harvesting unit extracting the electricity from a direct current environment energy source; and an electricity transmission unit controlling a transmission path of the electricity extracted from the direct current harvesting unit based on the magnitude of voltage of an alternating harvesting capacitor, which is an inner capacitor of the alternating current environment energy source, and the magnitude of voltage supplied from the direct current harvesting unit. 직류 하베스팅 에너지원 및 교류 하베스팅 에너지원을 이용한 에너지 하베스팅 장치 및 그 방법에 관한 것으로, 에너지 하베스팅 장치는 교류 환경 에너지원에서 전력을 추출하는 교류 하베스팅부와, 직류 환경 에너지원에서 전력을 추출하는 직류 하베스팅부 및 상기 교류 환경 에너지원의 내부 캐패시터인 교류 하베스팅 캐패시터의 전압의 크기 및 상기 직류 하베스팅부에서 인가되는 전압의 크기에 기초하여 상기 직류 하베스팅부에서 추출한 전력의 전달 경로를 제어하는 전력 전송부를 포함한다.
