【摘要】：隨著新能源、可再生能源發(fā)電及照明節(jié)能新技術(shù)的快速發(fā)展，適合于太陽能、燃料電池等新能源并網(wǎng)的寬增益DC/DC變換器拓撲，以及提高LED照明驅(qū)動電源壽命的AC/DC變換器拓撲，成為目前一個重要的研究方向。由于現(xiàn)有電力電子變換器拓撲的構(gòu)造都是采用經(jīng)驗的方法，，具有隨機性，且需耗費大量的人力、物力，往往事倍功半，提不出具有實用價值的電力電子變換器，為此研究具有系統(tǒng)性、可重復(fù)性的電力電子變換器拓撲構(gòu)造方法具有理論和實際意義。 本文根據(jù)電力電子變換器拓撲構(gòu)造特點，借鑒TRIZ發(fā)明創(chuàng)造理論中的套裝與合并原理，演繹出適合于電力電子變換器拓撲構(gòu)造的置換和嵌入方法，提出了一系列寬增益DC/DC變換器，AC/DC無橋變換器和無電解電容LED驅(qū)動電路。具體工作如下： 1.基于置換方法構(gòu)造寬增益DC/DC變換器的研究。提出了雙電感單元和開關(guān)電感電容單元兩種基本置換單元，將這兩種基本置換單元對傳統(tǒng)DC/DC變換器中的功率電感元件進行置換，構(gòu)造出了兩種寬增益Buck-Boost變換器、高增益N次型BOOST變換器，該方法還可推廣到寬增益Cuk、Sepic、Zeta變換器中。 2.基于嵌入方法構(gòu)造寬增益DC/DC變換器的研究。提出了無源嵌入單元和三種嵌入方法。構(gòu)造出了六種寬增益DC/DC變換器，即Sepic-Boost變換器、帶電壓乘法器的高增益變換器、反向輸出二次型Buck-Boost變換器、兩繞組倍壓高增益變換器和集成電壓轉(zhuǎn)移技術(shù)的高增益變換器。 3.基于置換和嵌入方法綜合的AC/DC變換器的研究。提出了一種Boost-Buck-Boost無橋變換器、一種偽連續(xù)Boost-Buck-Boost無橋變換器和一種Buck-Buck-Boost無橋變換器。 4.為解決LED驅(qū)動電源由于存在電解電容導(dǎo)致壽命降低的問題，基于嵌入方法提出了一種新型的無電解電容LED驅(qū)動電路。 以上研究表明，提出的適合于電力電子變換器拓撲構(gòu)造的置換和嵌入方法，可以系統(tǒng)地構(gòu)造出一系列新型的電力電子變換器拓撲，具有較好的實際價值。
[Abstract]:With the rapid development of new energy sources, renewable energy generation and lighting energy-saving technologies, it is suitable for the topology of wide-gain DC/DC converters connected to the grid of new energy sources such as solar energy, fuel cells, and so on. And the topology of AC/DC converter, which can improve the life of LED lighting driving power supply, has become an important research direction at present. Because the topology of current power electronic converter is constructed by experience method, it has randomness, and needs a lot of manpower and material resources, it often takes half the effort, and can not bring up the power electronic converter with practical value. Therefore, it is of theoretical and practical significance to study a systematic and repeatable topology construction method for power electronic converters. According to the characteristics of topology construction of power electronic converter, this paper deduces the replacement and embedding method suitable for topology construction of power electronic converter by referring to the combination and combination principle of TRIZ's theory of invention and creation, which is suitable for the topology construction of power electronic converter. A series of wide gain DC/DC converters, AC/DC bridge-less converters and electrolytic capacitor-free LED driving circuits are presented. The specific work is as follows: 1. The research of wide gain DC/DC converter based on permutation method. Two basic replacement units, double inductor unit and switched inductance capacitor unit, are proposed. Two kinds of wide gain Buck-Boost converters are constructed by replacing the power inductance elements of traditional DC/DC converter with these two basic replacement units. The high-gain N-order BOOST converter can also be extended to wide-gain Cuk,Sepic,Zeta converter. 2. The research of constructing wide gain DC/DC converter based on embedding method. Passive embedding elements and three embedding methods are proposed. Six kinds of wide gain DC/DC converters are constructed, that is, Sepic-Boost converter, high gain converter with voltage multiplier and backward output quadratic Buck-Boost converter. Two-winding double-voltage high-gain converter and high-gain converter integrated with voltage transfer technology. 3. The research of AC/DC converter based on substitution and embedding method. This paper presents a Boost-Buck-Boost bridge-less converter, a pseudo-continuous Boost-Buck-Boost bridge-less converter and a Buck-Boost bridge-less converter. 4. In order to solve the problem that the life of LED drive power supply is reduced due to electrolytic capacitance, a new type of electrolytic capacitor-free LED driving circuit is proposed based on embedding method. The above research shows that the proposed replacement and embedding method is suitable for the topology construction of power electronic converter, and a series of new power electronic converter topologies can be constructed systematically, which has a good practical value.
