多用太陽能手機充電器中英文資料

1、摘 要化石能源的日益枯竭、人們對環(huán)境保護問題的重視程度也在不斷提高，尋找潔凈的替代能源問題變得越來越迫切。太陽能作為一種可再生能源它具有取之不盡、用之不竭和清潔安全等特點，因此有著廣闊的應用前景，光伏發(fā)電技術也越來越受到人們的關注，隨著光伏組件價格的不斷降低和光伏技術的發(fā)展，太陽能光伏發(fā)電系統(tǒng)將逐漸由現在的補充能源向替代能源過渡。使用手機的人都有過這樣的經歷，外出或旅游時電池突然沒電了，因不能及時找到或沒有220v市電而無法給手機充電，影響了手機的正常使用。為了解決這一問題，本課程設計介紹一種多用太陽能手機充電器，利用單片機控制，將太陽能經過電路變換為穩(wěn)定直流電給手機充電，并能在電池充電完成后

2、自動停止充電，還可作為一般直流電源使用，從而擺脫對市電的依賴而獲得通信的自由。與常規(guī)的充電器相比，太陽能充電器有著明顯的優(yōu)勢。關鍵詞：太陽能，電池，單片機，智能，buck變換器multi-purpose solar mobile chargerabstractincreasing depletion of fossil energy, its emphasis on environmental protection are also rising, look for clean alternative energy issues become more urgent. solar energy

3、 as a renewable energy it has an inexhaustible and clean and safe and so on, so have a broad application prospects, photovoltaic power generation technology is more and more attention, with the pv module continue to lower prices and photovoltaic technology, solar pv systems will gradually supplement

4、 the energy from the current transition to alternative energy. people who use mobile phones have had the experience, go out or travel no electricity when the battery suddenly, and because they can not be found or does not timely 220v electricity and not to charge their cell phones affect the normal

5、use of mobile phones. to solve this problem, the course design introduces a multi-purpose solar charger, use mcu control, will transform solar energy through the circuit to stabilize the direct current to charge their cell phones and can charge the battery automatically stops charging after, but also as a general dc power use, so get rid of dependence on electricity obtained the freedom of communication. compared with the conventional charger, solar charger has a cle
