【正文】 ith good performance, can make the power electronic devices work in the switch state of ideal, shorten the switching time, reduce the switching loss. In addition, many protection link is located in the drive circuit or to achieve through the drive circuit. Trigger circuit and drive circuit is an important part of power electronic device. In order to ensure the normal operation and give full play to the potential of power electronic devices, device, must correct design and select trigger circuit and drive circuit. The trigger signal of the thyristor can be part of a positive half cycle of AC, DC is also available, can also be used short pulse. In order to reduce the gate loss, to ensure the accuracy of the trigger signal triggering time, often using pulse form. The thyristor trigger circuit of the basic requirements are as follows: Keywords: half control。 觸發(fā)電路與驅(qū)動(dòng)電路是電力電子裝置的重要組成部分。采用 性能良好的驅(qū)動(dòng)電路,可使電力電子器件工作在較理想的開關(guān)狀態(tài),縮短開關(guān)時(shí)間,減少開關(guān)損耗。 控制 GTR、 GTO、功率 MOSFET、 IGBT 等全控型器件的通斷則需要設(shè)置相應(yīng)的驅(qū)動(dòng)電路??刂凭чl管導(dǎo)通的電路稱為觸發(fā)電路。 課程設(shè)計(jì)說明書 電力電子技術(shù)課程設(shè)計(jì) 院 、 部: 電氣與信息工程學(xué)院 學(xué)生姓名: 指導(dǎo)教師: 職稱 副教授 專 業(yè): 自動(dòng)化專業(yè) 班 級(jí): 自本 1103 班 完成時(shí)間: 2022 年 5 月 28 日 摘要 普通晶閘管是半控型電力電子器件。為了使晶閘管由阻斷狀態(tài)轉(zhuǎn)入導(dǎo)通狀態(tài),晶閘管在承受正向陽極電壓的同時(shí),還需要在門極加上適當(dāng)?shù)挠|發(fā)電壓。觸發(fā)電路常以所組成的主要元件名稱進(jìn)行分類,包括簡單觸發(fā)電路、單結(jié)晶體管觸發(fā)電路、晶體管觸發(fā)電路、集成電路觸發(fā)器和計(jì)算機(jī)控制數(shù)字觸發(fā)電路等?;鶚O(門極、柵極)驅(qū)動(dòng)電路是電力電子主電路和控制電路之間的接口。另外,許多保護(hù)環(huán)節(jié)也設(shè)在驅(qū)動(dòng)電路或通過驅(qū)動(dòng)電路來實(shí)現(xiàn)。為了充分發(fā)揮電力電子器件的潛力、保證裝置的正常運(yùn)行,必須正確設(shè)計(jì)與選擇觸發(fā)電路與驅(qū)動(dòng)電路。 trigger。 trigger circuit. 目錄 1 晶閘管 ...................................................................................................................... 1 單向晶閘管 .................................................................................................... 1 雙向晶閘管 .................................................................................................... 3 2 晶閘管觸發(fā)電路 ...................................................................................................... 4 單向晶閘管觸發(fā)電路 ..................................................................................... 4 雙向晶閘管觸發(fā)電路 .................................................................................... 6 觸發(fā)電路工作原理 ........................................................................................ 7 鋸齒波的形成、脈沖移相環(huán)節(jié) ............................................................... 8 同步環(huán)節(jié) ...................................................................................................... 9 3 AT89C2051 的晶閘管觸發(fā)電路設(shè)計(jì) ................................................................... 11 觸發(fā)電路的硬件設(shè)計(jì) .................................................................................. 11 AT89C2051 簡介 ......................................................................................... 11 晶閘管觸發(fā)主電路 ...................................................................................... 12 觸發(fā)電路的軟件設(shè)計(jì) .................................................................................. 13 小結(jié) ............................................................................................................. 14 參考文獻(xiàn) ..........
