【導讀】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。展，太陽能光伏發(fā)電系統(tǒng)將逐漸由現(xiàn)在的補充能源向替代能源過渡。保護，最后，通過USB接口將穩(wěn)定直流電供給手機。另外，外觀設(shè)計為盆栽樹狀。以確保太陽能電池板采光充足。充電過程中采用LED燈、數(shù)碼管指示，系統(tǒng)中設(shè)。結(jié)構(gòu)和USB接口，可對手機，MP3、攝像機等多種數(shù)碼產(chǎn)品充電。供電，同時可為充電電池充電。軟件的設(shè)計采用模塊化設(shè)計方法，分為主程序部。分、數(shù)碼管顯示模塊、AD轉(zhuǎn)換采集模塊以PWM脈沖寬信號產(chǎn)生模塊等。
