驅動電(dian)路原理：

  驅動(dong)供電(dian)(dian)(dian)(dian)(dian)(dian)也由穩壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)分(fen)為+15V和-7.2V兩路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)源，以形成(cheng)對(dui)IGBT供電(dian)(dian)(dian)(dian)(dian)(dian)的(de)+15V激勵電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)回路(lu)(lu)和-7.2V的(de)截(jie)止電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)回路(lu)(lu)。驅動(dong)IC（A316J）的(de)左側(ce)(ce)引腳為輸(shu)入側(ce)(ce)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，右側(ce)(ce)引腳為輸(shu)出側(ce)(ce)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)。無論是脈(mo)沖(chong)(chong)信(xin)(xin)號還是OC故(gu)障信(xin)(xin)號，都由內部(bu)光(guang)耦(ou)合(he)器電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)相隔離(li)。由PC929相比(bi)，因內部(bu)已有對(dui)OC信(xin)(xin)號的(de)隔離(li)，可省去外接光(guang)耦(ou)合(he)器，并且脈(mo)沖(chong)(chong)信(xin)(xin)號、OC信(xin)(xin)號和故(gu)障復位信(xin)(xin)號可經控制端子CNN1直接與CPU脈(mo)沖(chong)(chong)輸(shu)出引腳相連。在有的(de)變頻器電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中，僅是下三臂(bei)IGBT驅動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)采用(yong)A316J，上三管采用(yong)TLP250等。

  其OC信號(hao)和復(fu)(fu)位信號(hao)端是并(bing)聯的，即檢測到(dao)任(ren)一臂IGBT有(you)過流(liu)故障(zhang)(zhang)時(shi)，都將(jiang)OC故障(zhang)(zhang)信號(hao)以或輸入(ru)方式，輸入(ru)到(dao)CPU；而(er)從(cong)CPU來(lai)的故障(zhang)(zhang)復(fu)(fu)位信號(hao)，也(ye)同時(shi)加到(dao)六片A316的6腳，將(jiang)整個驅動電(dian)路一同復(fu)(fu)位。驅動脈(mo)沖從(cong)A316J的11腳輸出(chu)，經R74、R75柵(zha)極電(dian)阻(zu)引入(ru)到(dao)模塊內部(bu)IGBT的G極。R77為柵(zha)極旁路電(dian)阻(zu)，Z34、Z35為柵(zha)、射(she)極正負偏(pian)壓嵌位穩壓管(guan)，保護(hu)IGBT的輸入(ru)回路的安全。

  A316J的14腳(jiao)外電(dian)(dian)路與16腳(jiao)引線并接于IGBT的C、E極，構成IGBT管(guan)壓降(jiang)檢測(ce)電(dian)(dian)路，電(dian)(dian)路僅由(you)R72、D61、C46三只元(yuan)件構成，C48吸收瞬態干擾，避免誤(wu)保護動(dong)作(zuo)出(chu)現。在11腳(jiao)輸(shu)出(chu)高電(dian)(dian)平驅動(dong)電(dian)(dian)壓期間(jian)，IGBT1的導通(tong)，使D61正(zheng)偏導通(tong)，將b點電(dian)(dian)位嵌制于OV驅動(dong)供(gong)電(dian)(dian)電(dian)(dian)位上(shang)。U31的14腳(jiao)輸(shu)入(ru)一個(ge)“IGBT良好開通(tong)"的低(di)(di)(di)電(dian)(dian)平信號(hao)，驅動(dong)脈(mo)沖被正(zheng)常(chang)傳(chuan)輸(shu)；因(yin)過流或IGBT低(di)(di)(di)效或損壞時，b、c兩點間(jian)電(dian)(dian)壓異常(chang)升(sheng)高，D61反偏截止(zhi)失(shi)去低(di)(di)(di)電(dian)(dian)平嵌位作(zuo)用，14腳(jiao)為高電(dian)(dian)平狀(zhuang)(zhuang)態，U31內(nei)部IGBT保護電(dian)(dian)路起(qi)控，將脈(mo)沖信號(hao)傳(chuan)輸(shu)通(tong)道鎖定，同時令(ling)5腳(jiao)輸(shu)出(chu)一個(ge)低(di)(di)(di)電(dian)(dian)平的OC信號(hao)，通(tong)知CPU。直到6腳(jiao)輸(shu)入(ru)一個(ge)CPU來(lai)的低(di)(di)(di)電(dian)(dian)平復位信號(hao)后，U31的故障鎖定狀(zhuang)(zhuang)態才(cai)被解除。

二、檢修步驟和方法：

  根據驅動(dong)電路(lu)相(xiang)關的(de)故障特(te)征，可以(yi)有的(de)放矢(shi)地進(jin)行檢查和修復(fu)了。

1、小功率變(bian)頻(pin)器，逆變(bian)輸出電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)采用集成型（一體化(hua)）模(mo)塊，引腳較多，而且直(zhi)接焊(han)接于電(dian)(dian)(dian)(dian)(dian)源(yuan)/驅(qu)(qu)動板上。在(zai)對驅(qu)(qu)動電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)上電(dian)(dian)(dian)(dian)(dian)進(jin)行(xing)電(dian)(dian)(dian)(dian)(dian)壓檢測前(qian)，必(bi)須先行(xing)切斷逆變(bian)模(mo)塊的(de)供電(dian)(dian)(dian)(dian)(dian)，待驅(qu)(qu)動電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)檢修(xiu)完畢后(hou)，再將逆變(bian)模(mo)塊的(de)供電(dian)(dian)(dian)(dian)(dian)恢復！

2、電路(lu)靜態(tai)測量(liang)（操作(zuo)控制(zhi)在停機狀態(tai)）：

  輸入側電(dian)路（A316J的(de)(de)4腳(jiao)為(wei)OV電(dian)位點）：3、4腳(jiao)之間有+5V的(de)(de)供電(dian)引入；1腳(jiao)信號輸入端(duan)(duan)為(wei)接近0V的(de)(de)低電(dian)平(ping)。5、6腳(jiao)為(wei)接近+5V的(de)(de)高電(dian)平(ping)。說明A316J輸入端(duan)(duan)靜態工作點基本正常。

A、若測得1腳有1V（比如+5V）以上的高電平信號(hao)輸(shu)入，檢查CNN1端子10到CPU脈(mo)沖輸(shu)出腳的脈(mo)沖信號(hao)傳輸(shu)通(tong)道，排除其(qi)故(gu)障；

B、若測得OC信(xin)號輸出腳(jiao)(jiao)6腳(jiao)(jiao)，為1V以(yi)下低電(dian)平，加熱焊點，用(yong)細鋼(gang)針挑開A316J的(de)(de)6腳(jiao)(jiao)與線路(lu)板的(de)(de)連(lian)接，原測量點電(dian)壓(ya)上升為+5V，說明6腳(jiao)(jiao)內(nei)部DMOS管子(zi)短路(lu)，更換A316J。測量點仍為低電(dian)平，檢(jian)查(cha)A316J的(de)(de)6腳(jiao)(jiao)至CPU引腳(jiao)(jiao)的(de)(de)相關電(dian)路(lu)，直到6腳(jiao)(jiao)電(dian)壓(ya)值恢復(fu)+5V的(de)(de)正常(chang)值為止；

C、若測(ce)(ce)得RST信(xin)號(hao)輸入腳(jiao)5腳(jiao)為(wei)1V 以下(xia)低電(dian)平，加熱焊點，用針挑開5腳(jiao)與線路板(ban)的連接(jie)，原(yuan)測(ce)(ce)量點電(dian)壓上升為(wei)+5V，說明A316的5腳(jiao)內部電(dian)路損壞，更換(huan)A316J；仍為(wei)低電(dian)平，檢查(cha)CPU主板(ban)電(dian)路。

輸出側電(dian)路（以(yi)16腳為O電(dian)位點）：

A、先(xian)檢查(cha)+15V、-7.2V的驅動供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源是否正常(chang)(chang)。若無(wu)負壓，檢查(cha)穩壓電(dian)(dian)(dian)(dian)(dian)(dian)路并排(pai)除；測得輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓偏低(di)，A316有(you)異常(chang)(chang)溫升，脫開柵極(ji)電(dian)(dian)(dian)(dian)(dian)(dian)阻R74，供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓正常(chang)(chang)，為模(mo)塊內部IGBT的G、E結(jie)漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)損(sun)壞(huai)，更(geng)換模(mo)塊；供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓仍低(di)，挑開A316的12/13腳，供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓恢復(fu)為正常(chang)(chang)值(zhi)，更(geng)換A316J；

B、測(ce)量UG、UE端子電(dian)壓(ya)應為(wei)-7V左右。測(ce)得(de)負(fu)壓(ya)僅為(wei)3V以下，測(ce)得(de)柵極電(dian)阻上(shang)有電(dian)壓(ya)降(jiang)，說明(ming)模塊內部(bu)IGBT的G、E結漏電(dian)損壞，更換(huan)逆變模塊；測(ce)得(de)柵極電(dian)阻上(shang)電(dian)壓(ya)降(jiang)為(wei)OV，更換(huan)A316J；

C、檢查(cha)R74、R75、Z34、Z35、R77等IGBT柵控回路元件，確保其正(zheng)常。

3、電路的動態檢測：

A、從三相供電電路(lu)中找到b、c、e、f點(dian)，并將b、c點(dian)和e、f點(dian)分(fen)別短(duan)接，以屏蔽驅動IC中IGBT保護電路(lu)OC故(gu)障報警功能，令CPU輸出六路(lu)脈(mo)沖信號；

B、配(pei)合操作顯示面板的(de)啟/停(ting)操作，可測(ce)出(chu)正常狀(zhuang)態下的(de)驅動電路的(de)輸入、輸出(chu)電壓值（數字(zi)表(biao)測(ce)得）：

注：各(ge)機型所(suo)測驅動(dong)脈沖的輸(shu)出信號電(dian)壓(ya)應相差不(bu)大，但輸(shu)入電(dian)壓(ya)值因(yin)(yin)各(ge)種因(yin)(yin)素的不(bu)同，可能(neng)有較大差異，但以(yi)動(dong)、靜態電(dian)壓(ya)值的顯著變化(hua)(hua)來判斷故障所(suo)在就(jiu)行了。顯然，用交流電(dian)壓(ya)檔，測量數值變化(hua)(hua)更(geng)為顯著。

a、檢(jian)測A316J的1、2腳之間輸(shu)入(ru)信號(hao)(hao)無變化，檢(jian)查CPU至(zhi)A316J的輸(shu)入(ru)信號(hao)(hao)通(tong)路，并將故障排除；

b、若檢測輸入信(xin)號正常，檢測UG、UE端子電(dian)壓(ya)，正常時(shi)交流電(dian)壓(ya)值約為14V左右；檢測輸出電(dian)壓(ya)偏低(di)，同時(shi)測量+15V供電(dian)電(dian)壓(ya)低(di)落(luo)，為電(dian)源(yuan)(yuan)帶負載(zai)能力不足，排(pai)除(chu)電(dian)源(yuan)(yuan)故障；檢查電(dian)源(yuan)(yuan)故障，可能為A316J內(nei)部輸出管低(di)效，導通(tong)內(nei)阻變大，更換AJ316。

4、檢(jian)查六(liu)路驅動脈沖電壓幅度都正常了，先別忙(mang)著裝機(ji)，在下一節專門(men)討論裝機(ji)過程中必須注意(yi)的問題。
