IC693PTM101CA 光伏電池的轉(zhuǎn)換效率取決于一系列變量,其中包括光照強(qiáng)度、電池的溫度、工作點(diǎn)以及電池的理論峰值效率。只要了解這些變量,就可以確定整個(gè)太陽(yáng)能面板的工作點(diǎn)。我們可用傳感器、微控制器和其他集成電路來(lái)監(jiān)測(cè)和調(diào)節(jié)工作電壓——容易受系統(tǒng)設(shè)計(jì)師控制的變量,并在條件下獲得大于10-15%的能量增益。這只是信息與通信技術(shù)如何提高光伏發(fā)電效率的其中一個(gè)范例。此外,它還可以添加額外功能,如提高水平、簡(jiǎn)化安裝、使維護(hù)更輕松便捷等。
光伏發(fā)電行業(yè)方興未已,成本效益和節(jié)能太陽(yáng)能系統(tǒng)架構(gòu)尚未成型。分布式電源管理系統(tǒng)似乎已為業(yè)界所認(rèn)可。然而,一個(gè)問(wèn)題是,究竟是讓能源以直流電壓的形式在系統(tǒng)中傳輸,還是采用微型變流技術(shù)將每塊面板的輸出從直流電轉(zhuǎn)換成交流電,兩者孰優(yōu)?無(wú)論系統(tǒng)架構(gòu)如何競(jìng)爭(zhēng),都已蓄勢(shì)待發(fā),準(zhǔn)備潮流。
在這兩種提高光伏發(fā)電效率的方法中,優(yōu)化設(shè)計(jì)和提高半導(dǎo)體性能尤為重要,而在這些方面都已做出了重大貢獻(xiàn)。公司近推出了MPT612,一種專門執(zhí)行功率點(diǎn)跟蹤(MPPT)功能的低功耗集成電路,能夠優(yōu)化太陽(yáng)能應(yīng)用的電力提取效率。以電池充電為例,當(dāng)MPT612在運(yùn)行即將獲得專利的MPPT算法時(shí),它從一塊太陽(yáng)能面板提取的能量比傳統(tǒng)的控制器要高出30%以上。
