Abstract
In this paper a photovoltaic energy harvesting charger with battery management circuit is proposed. The proposed circuit harvests maximum power from a solar cell by employing MPPT(Maximum Power Point Tracking) control and charges an external capacitor battery with the harvested energy. The charging state of the battery is controlled according to the signals from the battery management circuit. The proposed circuit is designed in a 0.35um CMOS process technology and its functionality has been verified through extensive simulations. The maximum efficiency of the designed entire system is 84.8%, and the chip area including pads is
본 논문에서는 배터리 관리 기능을 갖는 빛 에너지 하베스팅 충전기 회로를 제안하였다. 제안된 회로는 MPPT(Maximum Power Point Tracking)를 통해 빛 에너지를 솔라 셀로부터 수확하고, 수확한 에너지를 외부 배터리 커패시터에 연결하여 충전한다. 배터리 관리회로(Battery Management)의 신호에 따라, 배터리 커패시터의 충전 상태를 조절한다. 제안된 회로는 0.35um CMOS 공정으로 설계하였으며, 모의실험을 통해 동작을 검증하였다. 설계된 회로의 최대효율은 84.8%이며, 칩 면적은 패드를 포함하여
