INDEPENDENT PHOTOVOLTAIC POWER GENERATION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide an independent photovoltaic power generation system/ method which can safely and surely charge an electric power accumulation device with desired current/voltage by means of a solar battery having unstable generated output. SOLUTION: This system includes a 1st converter 2 which is connected to the output of a solar battery 1, an electric double layer capacitor 5 which is connected to the output of the converter 2, an Ni-MH accumulator 6 which is charged by a charger 7 connected to the output of the converter 2, a 2nd converter 3 which is connected to the output of the converter 2 and the output of the capacitor 5 and also connected to the battery 6 via a reverse current prevention diode 8 and a load 4 which is connected to the output of the converter 3.
