摘 要:隨著地球上石油、煤炭、天然氣等傳統(tǒng)不可再生資源的日益減少，外加日漸嚴(yán)重的化石燃料燃燒產(chǎn)生的環(huán)境污染，人們開(kāi)始發(fā)掘和探索太陽(yáng)能作為替代者。地球上94%的能源由太陽(yáng)能提供，根據(jù)目前太陽(yáng)產(chǎn)生的核能速率估算，氫的儲(chǔ)量足夠維持600億年，而地球內(nèi)部組織因熱核反應(yīng)聚合成氫，壽命約為50億年，從這個(gè)意義上講，太陽(yáng)能是取之不盡，用之不竭的。 太陽(yáng)能路燈是有效利用太陽(yáng)能的一種方式，由太陽(yáng)能電池板、蓄電池、控制器、負(fù)載以及燈桿組成。能夠?qū)崿F(xiàn)白天充電，晚上放電的功能。它利用光生伏打效應(yīng)將太陽(yáng)能轉(zhuǎn)化為電能儲(chǔ)存在蓄電池中，再通過(guò)控制器向負(fù)載供電。 太陽(yáng)能路燈系統(tǒng)能夠?qū)崿F(xiàn)充放電保護(hù)及各種短路保護(hù)，通過(guò)最大功率點(diǎn)跟蹤算法在固定電池板傾角的情況下實(shí)現(xiàn)高轉(zhuǎn)化率，高利用率。 關(guān)鍵詞：光生伏打效應(yīng) 硬件設(shè)計(jì) 充放電控制MPPT算法
ABSTRACT:With the shrinking of such as oil, coal, natural gas on earth of the traditional non-renewable resources, coupled with increasingly serious environmental pollution from the burning of fossil fuels, people began to discover and explore solar as a replacement. 94% of earth's energy provided by solar energy, according to the current rate of the sun produces nuclear energy estimation, hydrogen storage of enough to maintain in 60 billion, and earth's internal organization because thermonuclear reaction polymerization into hydrogen, life is about 5 billion years, in this sense, the solar energy is inexhaustible, inexhaustible. Solar street light is an effective way of using solar energy, from solar panels, battery, controller, the load and the composition of light pole. The function of the discharge can achieve charge during the day, night. It uses photovoltaic effect converts solar energy into electrical energy stored in the battery, then supply power to load by the controller. Solar street light system is able to realize the charge and discharge protection and short circuit protection, by maximum power point tracking algorithm under the condition of the fixed panel Angle to achieve high conversion rate, high utilization rate.
