逆變電路
? ? 逆變電路的作用是在控制電路的作用下，將直流電路輸出的直流電源轉(zhuǎn)換成頻率和電壓都可以任意調(diào)節(jié)的交流電源。逆變電路的輸出就是變頻器的輸出，所以逆變電路是變頻器的核心電路之一，起著非常重要的作用。
? ? 最常見的逆變電路結(jié)構(gòu)形式是利用六個(gè)功率開關(guān)器件（GTR、IGBT、GTO等）組成的三相橋式逆變電路，有規(guī)律的控制逆變器中功率開關(guān)器件的導(dǎo)通與關(guān)斷，可以得到任意頻率的三相交流輸出。
? ? 通常的中小容量的變頻器主回路器件一般采用集成模塊或智能模塊。智能模塊的內(nèi)部高度集成了整流模塊、逆變模塊、各種傳感器、保護(hù)電路及驅(qū)動(dòng)電路。如三菱公司生產(chǎn)的IPMPM50RSA120，富士公司生產(chǎn)的7MBP50RA060，西門子公司生產(chǎn)的BSM50GD120等，內(nèi)部集成了整流模塊、功率因數(shù)校正電路、IGBT逆變模塊及各種檢測(cè)保護(hù)功能。模塊的典型開關(guān)頻率為20KHz，保護(hù)功能為欠電壓、過電壓和過熱故障時(shí)輸出故障信號(hào)燈。?逆變電路中都設(shè)置有續(xù)流電路。續(xù)流電路的功能是當(dāng)頻率下降時(shí)，異步電動(dòng)機(jī)的同步轉(zhuǎn)速也隨之下降。為異步電動(dòng)機(jī)的再生電能反饋至直流電路提供通道。在逆變過程中，寄生電感釋放能量提供通道。另外，當(dāng)位于同一橋臂上的兩個(gè)開關(guān)，同時(shí)處于開通狀態(tài)時(shí)將會(huì)出現(xiàn)短路現(xiàn)象，并燒毀換流器件。所以在實(shí)際的通用變頻器中還設(shè)有緩沖電路等各種相應(yīng)的輔助電路，以保證電路的正常工作和在發(fā)生意外情況時(shí)，對(duì)換流器件進(jìn)行保護(hù)。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國(guó)內(nèi)實(shí)力庫存商家


選擇深圳長(zhǎng)欣，選擇放心，售后無憂大量現(xiàn)貨，當(dāng)天順豐發(fā)貨！
主營(yíng)：本特利，英維思，伍德沃德，福克斯波羅、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂，ACSO，力士樂等各大品牌的DCS系統(tǒng)配件，機(jī)器人系統(tǒng)配件，大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”（不管能不能看懂，先了解個(gè)大概，以便學(xué)習(xí)編程時(shí)查找）；
2、由位控邏輯入手，逐漸增加定時(shí)、計(jì)數(shù)等條件，把或、與、非關(guān)系理順；
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換；
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解（最好是有個(gè)物理回路驗(yàn)證，比如變頻器+電機(jī)+測(cè)速傳感器）；
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制（盡量避免跳轉(zhuǎn)，非跳不可時(shí)也是跳的越近越好）；
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列，GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌，由于PLC的基本框架大同小異，學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡(jiǎn)單了。
