【摘要】：目前,隨著電力電子等技術(shù)的發(fā)展,對(duì)高性能電力需求不斷增加,使得大量開(kāi)關(guān)電源變換器被廣泛用于軍事、工業(yè)、商業(yè)等領(lǐng)域。性能優(yōu)異的開(kāi)關(guān)電源變換裝置可以提供給設(shè)備優(yōu)質(zhì)的電能,從而極大限度地提升產(chǎn)品質(zhì)量。但同時(shí),為了達(dá)到提升電能質(zhì)量以及產(chǎn)品整體性能的目的,開(kāi)關(guān)器件的開(kāi)關(guān)頻率不斷增加,開(kāi)關(guān)電源體積不斷減小,由此而帶來(lái)的電磁兼容問(wèn)題成為制約開(kāi)關(guān)電源發(fā)展的一個(gè)關(guān)鍵技術(shù)難點(diǎn)。本文針對(duì)高性能開(kāi)關(guān)電源的電磁兼容性問(wèn)題,研究了以下三個(gè)部分內(nèi)容：1、DC-DC開(kāi)關(guān)電源的架構(gòu)。通過(guò)對(duì)buck型開(kāi)關(guān)電源的原理進(jìn)行分析,找出影響開(kāi)關(guān)電源性能的關(guān)鍵點(diǎn),進(jìn)行針對(duì)性設(shè)計(jì),從而對(duì)電路進(jìn)行優(yōu)化,提高開(kāi)關(guān)電源的工作性能。2、濾波電路的設(shè)計(jì)。通過(guò)對(duì)應(yīng)用對(duì)象的分析,根據(jù)應(yīng)用對(duì)象的工作頻率來(lái)設(shè)計(jì)濾波電路,從而滿(mǎn)足工作要求。3.腔體結(jié)構(gòu)的設(shè)計(jì)。通過(guò)對(duì)影響電磁兼容性因素的分析,設(shè)計(jì)自己的腔體結(jié)構(gòu),提高電源的電磁兼容性。基于以上的研究,制作了樣機(jī)并進(jìn)行相關(guān)實(shí)驗(yàn),給出了實(shí)驗(yàn)結(jié)果和實(shí)驗(yàn)性能參數(shù)。
[Abstract]:At present, with the development of power electronics and other technologies, the demand for high performance power is increasing, which makes a large number of switching power converters widely used in military and industry. Commercial and other fields. Excellent switching power conversion device can provide high quality electrical energy to equipment, thus greatly improve the quality of products. But at the same time. In order to improve the power quality and the overall performance of the product, the switching frequency of switching devices is increasing, and the volume of switching power supply is decreasing. The electromagnetic compatibility (EMC) problem has become a key technical difficulty that restricts the development of switching power supply. In this paper, the following three parts: 1 are studied in order to solve the EMC problem of high performance switching power supply. The structure of DC-DC switching power supply. Through the analysis of the principle of buck switching power supply, the key points that affect the performance of switching power supply are found out, and the targeted design is carried out, so as to optimize the circuit. Through the analysis of the application object, the filter circuit is designed according to the working frequency of the application object. In order to meet the requirements of the work. 3. Cavity structure design. Through the analysis of the factors affecting electromagnetic compatibility, design their own cavity structure, improve the electromagnetic compatibility of power supply. Based on the above research. The prototype is made and related experiments are carried out. The experimental results and experimental performance parameters are given.
