【摘要】：現(xiàn)代社會的進步以及經(jīng)濟發(fā)展的推進力以能源為根本,能源也是人類日常生活不可缺少的物質(zhì)保障。然而當(dāng)前人類雖然能享受著能源給予的各項福利,但是還面臨著一系列不可避免的諸如能源不足和化石能源過度消耗以及其帶來的環(huán)境質(zhì)量破壞等能源安全危機,嚴重妨礙人類生活和進步。所以我們要加快新能源的開發(fā),提高科技水平,才能在資源匱乏和環(huán)境問題突出的今天處理好社會發(fā)展的可持續(xù)問題。太陽能是上天賜予我們一個純天然的可使用量巨大的可循環(huán)再生的資源,它使用過程中具有潔凈、簡單易得、藏量巨大的特點。它的使用能給環(huán)境保護、全球變暖和資源匱乏現(xiàn)狀提供一個高效處理的方式,是當(dāng)今替代不可再生能源較為優(yōu)越的資源之一。此外,采用電網(wǎng)進行電能的輸送往往會受到地域的限制,從而造成部分山區(qū)以及偏遠地區(qū)無電可用的情況,所以本文針對戶用光伏逆變電源展開研究,研制出的性能穩(wěn)定、優(yōu)越的系統(tǒng)必將為改善人們的生活起到極致的促進作用。針對戶用光伏逆變電源系統(tǒng),筆者對其主要的四個部件進行了簡單地介紹,其中太陽能電池作為最關(guān)鍵的一個部件,本文著重研究了其特性,由于其具有價格高昂和輸出非線性這兩個問題,為使太陽能得到盡可能地利用,以便提升工作效率并降低成本,本文對最大功率跟蹤法進行了研究。為此,本文通過軟件對這兩個方面均進行模擬研究,用理論來指導(dǎo)模型,亦反過來用模型驗證理論。但從另一方面來看,蓄電池因其容易受到損傷與破壞的特性,是所有環(huán)節(jié)中最脆弱的一部分,因此可以說蓄電池的性能優(yōu)劣對于系統(tǒng)整體的穩(wěn)定性起到至關(guān)重要的作用。本設(shè)計根據(jù)系統(tǒng)在溫度與光照兩個方面的特性,充電過程中額外補充了涓流與浮充兩個階段,即為四階段充電法,該方法可以實現(xiàn)充電過程的最優(yōu)化。本文DC-DC變換器使用了BOOST電路,主要是由電感、二極管等部件組成,DC-DC變換部分的目的是實現(xiàn)功率。DC-AC逆變部分的電路,主要是利用了全橋逆變的方式,其主要是通過IGBT開關(guān)管,以及并聯(lián)的二極管等組成的。為了可以保證系統(tǒng)的各類電源可以得到足夠的芯片工作電源,本文的輔助電源設(shè)計活動中主要使用了Topswitch器件來幫助,電池組件的輸出電壓就是輸入的太陽能電池電壓。由于EMI信號在輸出信號的時候,會對電磁環(huán)境帶來比較嚴重的污染,同時也會嚴重地干擾到電子產(chǎn)品和通信設(shè)備,本文分析了其中的電池干擾問題,并提出了這一問題的產(chǎn)生原因,并給出了相應(yīng)的解決策略。本文選取了TI公司的DSP(TMS320F2407 A)來充當(dāng)電路中的主控制芯片。筆者以上面的設(shè)計為基礎(chǔ),最終將一套700W的戶用光伏逆變電源系統(tǒng)開發(fā)了出來,試驗結(jié)果表面,系統(tǒng)有著比較好的運行效果,很多預(yù)期設(shè)計和指標都比較相符。
[Abstract]:The progress of modern society and the propelling force of economic development are based on energy, which is also an indispensable material guarantee for human daily life.However, although mankind can enjoy the benefits of energy, it still faces a series of inevitable energy security crises, such as insufficient energy, excessive consumption of fossil energy and environmental quality damage.It is a serious obstacle to human life and progress.Therefore, we should speed up the development of new energy and raise the level of science and technology, so that we can deal with the sustainable problem of social development well today with the shortage of resources and the outstanding environmental problems.Solar energy is a pure natural renewable resource which can be used in large quantities. It has the characteristics of clean, simple and easy to obtain, and huge storage in the process of use.Its use can provide an efficient way to deal with environmental protection, global warming and resource scarcity. It is one of the superior resources to replace non-renewable energy.In addition, the use of electric power grid is often limited by the region, resulting in some mountain areas and remote areas where there is no electricity, so this paper studies the household photovoltaic inverter power supply, the performance of the development is stable,Superior systems are bound to play an extremely important role in improving people's lives.For the household PV inverter power system, the author briefly introduces its four main components, among which the solar cell as the most critical component, this paper focuses on its characteristics.Due to its high price and nonlinear output, the maximum power tracking method is studied in this paper in order to maximize the utilization of solar energy in order to improve the efficiency and reduce the cost.In this paper, the two aspects are simulated by software, and the theory is used to guide the model, and in turn, the theory of model verification is used.But on the other hand, the battery is the most vulnerable part of all links because of its easy damage and damage, so it can be said that the performance of the battery plays a vital role in the overall stability of the system.According to the characteristics of the system in temperature and light, the trickle and floating charging stages are added in the charging process, that is, the four-stage charging method. This method can realize the optimization of the charging process.In this paper, BOOST circuit is used in DC-DC converter, which is composed of inductor, diode and other components. The purpose of this converter is to realize the circuit of power. DC-AC inverter part. It mainly uses the full-bridge inverter mode, which is mainly through the IGBT switch tube.And parallel diodes, etc.In order to ensure that all kinds of power supply of the system can get enough chip power supply, Topswitch devices are mainly used in the auxiliary power design activities. The output voltage of the battery module is the input solar cell voltage.Since the EMI signal will bring serious pollution to the electromagnetic environment when it outputs the signal, it will also seriously interfere with the electronic products and communication equipment. This paper analyzes the battery interference problem.The causes of this problem are put forward, and the corresponding solutions are given.In this paper, TI's DSP(TMS320F2407 A is chosen as the main control chip in the circuit.On the basis of the above design, the author has developed a set of 700W photovoltaic inverter power supply system. The test results show that the system has a good operation effect, and many expected designs and specifications are in accordance with each other.
