【正文】 度。PV系統(tǒng)的輸出功率受輻射照度的強(qiáng)烈影響，也受太陽(yáng)能電池組件內(nèi)的太陽(yáng)能電池單元的溫度影響，因此用在日照強(qiáng)度為1kw/m單元溫度為25攝氏度的標(biāo)準(zhǔn)條件下的最大輸出功率表示標(biāo)準(zhǔn)太陽(yáng)能電池陣列的輸出功率。太陽(yáng)能電池鎮(zhèn)流是有太陽(yáng)能電池組件集合體的太陽(yáng)能電池組件串、防止逆流元件、旁路元件和接線箱等構(gòu)成的。太陽(yáng)能功能電池組件就是將數(shù)十個(gè)太陽(yáng)能電池單元進(jìn)行耐候性封裝。太陽(yáng)能是一種輻射能，它必須借助于能量轉(zhuǎn)換器才能轉(zhuǎn)換成為電能。其原因可能是人們對(duì)信息的追求特別強(qiáng)烈，而常規(guī)能源還能滿足人類對(duì)能源的需求。本課題主要研究光伏發(fā)電系統(tǒng)中的逆變器，逆變器是一種將直流電能變換成交流電能的變流裝置。真正將太陽(yáng)能作為“近期急需的補(bǔ)充能源”，“未來(lái)能源結(jié)構(gòu)的基礎(chǔ)”，則是近來(lái)的事。 the output voltage of the RMS is changed. Because of this circuit has freewheeling loop, even to the perceptual load, the output voltage waveform nor distortion. This circuit faults is under the arm, bridge, no power transistor must therefore be adopted by isolating circuit or special driving power.These kinds of inverter circuit are needed to control circuit, general square wave and are weak wave two control mode, the output pulse inverter circuit is simple, low cost, low efficiency, harmonic ponents. Sine wave output is the development trend of the inverter, along with the development of microelectronics technology, PWM function of micro processor is also available, so the sinusoidal output inverter technology has matured.Key word：Solar energy。由于該電路具有續(xù)流回路，即使對(duì)感性負(fù)載，輸出電壓波形也不會(huì)畸變。光伏板組件是一種暴露在陽(yáng)光下便會(huì)產(chǎn)生直流電的發(fā)電裝置，由幾乎全部以半導(dǎo)體物料(例如硅)制成的薄身固體光伏電池組成。摘 要 由于全球能源的逐漸緊張和環(huán)境污染的日益嚴(yán)重，清潔的可再生的太陽(yáng)能越來(lái)越受到人們是重視。為人類創(chuàng)造了一種新的生活形態(tài)，使社會(huì)及人類進(jìn)入一個(gè)節(jié)約能源減少污染的時(shí)代。我們主要研究光伏發(fā)電系統(tǒng)中的逆變電路而其中的電壓型單相全橋逆變電路是我們所要詳細(xì)研究的對(duì)象，.而其中本論文會(huì)涉及最大功率跟蹤及PWM控制技術(shù)全橋逆變電路克服了推挽電路的缺點(diǎn)，功率晶體管調(diào)節(jié)輸出脈沖寬度，輸出交流電壓的有效值即隨之改變。關(guān)鍵詞：太陽(yáng)能；光伏系統(tǒng)；逆變器技術(shù)；正弦波輸出Solar Photovoltaic System Inverter ApplicationsLEE ZhishunAbstractDue to tight global energy and environmental pollution gradually growing, clean, renewable solar energy more and more people are seriously.Solar energy is the first time, but also renewable energy. It is rich in resources, can use free of charge, and without transportation, without any pollution to the environment. For mankind to create a new life, so that social and human energy into a era of reducing pollution.Is a ponent of photovoltaic panels in the sun exposure will generate direct current power generation devices, from virtually all semiconductor materials (eg silicon) are made of thin photovoltaic cells posed of solid. Because there is no part of activity, and would thus be a long time operation would not lead to any loss. Simple photovoltaic cells for watches and puters to provide energy, and more plex PV systems to provide lighting for the housing and power supply.we almost go deeply into the source inverter in PV systems，and the Voltage SinglePhase FullBridge Controlled Rectifier is the most important simple for us to research, as thus it will relate to MPPT and PWM controller technology,The bridge has pushpull inverter circuit to overe the shorting, power transistor circuits of the output pulse width adjustment。 Sine wave output目 錄１．緒論.................................................．．...．．．．.....1　?。薄　。病　。场　。▎蜗啵础　。叮玻夥到y(tǒng)的組成．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．６．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．６．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．７３．光伏并網(wǎng)系統(tǒng)的工作原理．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．７．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．７．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．９．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．９．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１０４．PWM型逆變電路．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１０．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１０．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１１．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１３．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１３．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１３．．．．．．．．．．．．．．．．．．．．．．．．．．１４．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１５．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１６．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１７．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１７５．軟件部分及結(jié)論．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１９．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１９．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．２１．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．２１．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．２２總結(jié)．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．２２參考文獻(xiàn)．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．
