25、力領域的電子技術,就是使用電力電子器件(如晶 閘管)對電能進行變換和控制的技術。 電力電子技術所變換的“電力”功率可大到數(shù)百 MWS 至GW也可以小到數(shù) W甚至1W以下,和以信息處理為主的信息電子技術不同電力電子技術主 要用于電力變換。通過電力電子技術對電能的處理,使電能的使用達到合理、高效和節(jié) 約,實現(xiàn)電能使用最佳化。電力電子技術分為電力電子器件制造技術和變流技術(整流,逆變,斬波,變頻,變相等)兩個分支。變流技術也稱為電力電子技術的應用技術,它 包括用電力電子器件構成各種電力變換電路和對這些電路進行控制的技術,以及由這些電路構成電力電子裝置和電力電子系統(tǒng)的技術。變流技術是電力電子技術的核心
26、,變流 技術的理論基礎是電路理論。整流電路是電力電子電路的一種,將交流電變?yōu)橹绷麟?,應用十分廣泛,電路形式 多種多樣。按組成器件可分為不可控、半控、全控三種;按電路結構可分為橋式和零式 電路;按交流輸入相數(shù)分為單相電路和多相電路。這次課程設計我們設計的是單相橋式全控整流電路,與單相半波可控整流電路相 比,橋式全控的電源利用率高一些,應用范圍更廣。uptd, mplmetai3icea 5%lge eg a ueat g 1m.e.,eielt-Lc- s-s dlea est yt-d e ds.i u - ci c -u- - uaeede et i a lua .- Pkd.it-i u

29、統(tǒng)的能力。2)較全面地鞏固和應用本課程所學知識和基本方法,初步掌握整流電路的設計方法。3)培養(yǎng)獨立思考,獨立收集材料,獨立實際的能力。4)熟悉電力電子技術的課程和一些相關知識。1.2 課程設計的總體要求1)負載:電阻電感性負載2)電感 L=700mh , R=500C3) 電網提供的電壓為 220V, 50H4)輸出電壓0100V輸出功率1KW5)移相范圍090i.ul - -mid t u-e payi-iIs and lad- I g ore s p-pery. their po r s S - ond srongif 75%ll vt l b tv f 500 li Y Pitl t i

36、阻一電感性負載和反電動勢負 載的工作情況。本組所做的是單相橋式全控整流電路。與單相橋式半空整流電路相比,無需接續(xù)流二極管, 也不會出現(xiàn)失控的現(xiàn)象,負載形式多樣,整流效果好,波形平穩(wěn),應用廣泛。變壓器二次繞 組中,正負兩個半周電流方向相反且波形對稱,平均值為零,即直流分量為零,不存在變壓 器直流磁化問題,變壓器的利用率也高。單相全控橋式整流電路具有輸出電流脈動小,功率因數(shù)提高,變壓器二次側電流為兩個等大反向的半波,沒有直流磁化的問題,變壓器利用率高的優(yōu)點。單相全控橋式整流電路其輸出平均電壓是半波電路的2倍,在相同的負載下流過晶閘管的平均電流減小一半,且功率因數(shù)提高了一半。2.2 觸發(fā)電路的要求及
