隨著時間推移(yi)供(gong)用電(dian)(dian)(dian)網絡(luo)技術采(cai)用水(shui)平的(de)成(cheng)長 和技術采(cai)用特(te)色化(hua)(hua)，轉(zhuan)換(huan)按(an)鈕(niu)主(zhu)機(ji)外(wai)(wai)(wai)接(jie)(jie)主(zhu)機(ji)旋鈕(niu)電(dian)(dian)(dian)源開(kai)(kai)(kai)關(guan)技術采(cai)用水(shui)平也在一個(ge)勁(jing)技術采(cai)用特(te)色化(hua)(hua)。當下(xia)，轉(zhuan)換(huan)按(an)鈕(niu)主(zhu)機(ji)外(wai)(wai)(wai)接(jie)(jie)主(zhu)機(ji)旋鈕(niu)電(dian)(dian)(dian)源開(kai)(kai)(kai)關(guan)故有大小小、稱(cheng)重輕(qing)、使(shi)用率高教優越性被寬(kuan)泛(fan)采(cai)用于近(jin)乎各(ge)種(zhong)的(de)網絡(luo)環保設(she)備中。轉(zhuan)換(huan)按(an)鈕(niu)主(zhu)機(ji)外(wai)(wai)(wai)接(jie)(jie)主(zhu)機(ji)旋鈕(niu)電(dian)(dian)(dian)源開(kai)(kai)(kai)關(guan)是網絡(luo)資料加工業很快成(cheng)長 的(de)一個(ge)不得緊(jin)缺的(de)主(zhu)機(ji)外(wai)(wai)(wai)接(jie)(jie)主(zhu)機(ji)旋鈕(niu)電(dian)(dian)(dian)源開(kai)(kai)(kai)關(guan)傳統(tong)模式，正是因為轉(zhuan)換(huan)按(an)鈕(niu)主(zhu)機(ji)外(wai)(wai)(wai)接(jie)(jie)主(zhu)機(ji)旋鈕(niu)電(dian)(dian)(dian)源開(kai)(kai)(kai)關(guan)的(de)工作的(de)原去(qu)理有所(suo)為不相同(tong)。
一、按(an)鈕開關主機電源線(xian)(xian)(xian)路(lu)由復制粘貼電磁感應侵擾濾(lv)(lv)波器(qi)(EMI)、整流(liu)濾(lv)(lv)波三極管(guan)、電率變換三極管(guan)、PWM的(de)傳感器(qi)線(xian)(xian)(xian)路(lu)和輸(shu)送整流(liu)濾(lv)(lv)波線(xian)(xian)(xian)路(lu)構(gou)成，助手線(xian)(xian)(xian)路(lu)收(shou)錄鍵入欠(qian)壓(ya)呵護(hu)線(xian)(xian)(xian)路(lu)、輸(shu)送欠(qian)壓(ya)呵護(hu)線(xian)(xian)(xian)路(lu)、輸(shu)送過瞬時電流(liu)呵護(hu)線(xian)(xian)(xian)路(lu)、輸(shu)送虛接呵護(hu)線(xian)(xian)(xian)路(lu)等(deng)。
二、 進(jin)入電線(xian)的方式及常有電線(xian)：
1、AC 投入整流濾波電路板的原理：
A.防電(dian)雷(lei)路(lu)：當(dang)有(you)被雷(lei)擊(ji)，形(xing)成直流電(dian)經(jing)電(dian)力系統引入交(jiao)流電(dian)源時，由(you) MOV1、MOV2、MOV3：F1、F2、F3、 FDG1 組(zu)合(he)而(er)成的(de)電(dian)路(lu)原理去維(wei)修。當(dang)加在(zai)壓(ya)敏熱敏阻(zu)值(zhi)(zhi)倆(lia)頭的(de)輸(shu)出(chu)功(gong)率逾越(yue)其家庭作業輸(shu)出(chu)功(gong)率時，其阻(zu)值(zhi)(zhi)減退， 使超高壓(ya)能源總(zong)量在(zai)壓(ya)敏熱敏阻(zu)值(zhi)(zhi)上，若交(jiao)流電(dian)過大，F1、F2、F3 會焚毀系統維(wei)護后(hou)級電(dian)路(lu)板(ban)。
B.進(jin)(jin)入濾波用(yong)電(dian)(dian)(dian)線(xian)路：C1、L1、C2、C3 根據的(de)雙(shuang) π 型濾波數據網(wang)絡(luo)主(zhu)要(yao)(yao)是(shi)對(dui)錄(lu)入主(zhu)機(ji)電(dian)(dian)(dian)原線(xian)的(de)電(dian)(dian)(dian)磁(ci)波背景(jing)噪聲 及雜波信號(hao)燈進(jin)(jin)行(xing)抑制，以免(mian)對(dui)主(zhu)機(ji)電(dian)(dian)(dian)原線(xian)攪(jiao)擾，一起去(qu)也以免(mian)主(zhu)機(ji)電(dian)(dian)(dian)原線(xian)客觀存在突發的(de)低頻(pin)雜波對(dui)輸電(dian)(dian)(dian)攪(jiao)擾。 當主(zhu)機(ji)電(dian)(dian)(dian)原線(xian)開放瞬(shun)(shun)息(xi)，要(yao)(yao)對(dui) C5 充(chong)電(dian)(dian)(dian)器，如果快速功(gong)率大，加 RT1（熱敏功(gong)率電(dian)(dian)(dian)阻）就能合理的(de)預防(fang)浪 涌感應電(dian)(dian)(dian)流(liu)。因(yin)瞬(shun)(shun)時熱量(liang)全使(shi)用(yong)在 RT1 功(gong)率電(dian)(dian)(dian)阻上(shang)，特定時候后(hou)溫度變(bian)高后(hou) RT1 阻值變(bian)大（RT1 是(shi)負(fu) 溫公式電(dian)(dian)(dian)子器件），這(zhe)是(shi)它需求的(de)養分相當小，后(hou)級電(dian)(dian)(dian)路原理可沒問題使(shi)用(yong)。
C.整流(liu)濾波(bo)電(dian)路(lu)板：交流(liu)與溝(gou)通(tong)電(dian)壓降經 BRG1 整流(liu)后，經 C5 濾波(bo)后能夠得到最為(wei)純(chun)凈版(ban)的(de)(de)直流(liu)電(dian)電(dian)流(liu)電(dian)壓。若 C5 使用量(liang)變小，內(nei)容輸(shu)出的(de)(de)溝(gou)通(tong)能力紋波(bo)將變大。
2、 DC 放入濾(lv)波電路(lu)板方法：
A.導入(ru)濾(lv)波(bo)(bo)電(dian)(dian)(dian)線：C1、L1、C2 根據的(de)雙 π 型(xing)濾(lv)波(bo)(bo)網(wang)上具(ju)體(ti)是(shi)對輸進外(wai)接電(dian)(dian)(dian)壓的(de)電(dian)(dian)(dian)磁能燥聲(sheng)及雜 波(bo)(bo)網(wang)絡(luo)信號(hao)開展按奈，制(zhi)止(zhi)對外(wai)接電(dian)(dian)(dian)壓攪(jiao)擾，最大的(de)也制(zhi)止(zhi)外(wai)接電(dian)(dian)(dian)壓身再(zai)次(ci)發生的(de)中頻雜波(bo)(bo)對國家電(dian)(dian)(dian)網(wang)攪(jiao)擾。C3、 C4 為安規電(dian)(dian)(dian)容(rong)（電(dian)(dian)(dian)容(rong)器），L2、L3 為差模(mo)電(dian)(dian)(dian)感(gan)。
B.R1、R2、R3、Z1、C6、Q1、Z2、R4、R5、Q2、RT1、C7 組(zu)合成抗(kang)浪涌三極管。在(zai)起機的(de)(de)一瞬， 而是 C6 的(de)(de)長(chang)期(qi)存在(zai) Q2 不導通，電(dian)(dian)(dian)流值經 RT1 涉及雙回路(lu)(lu)。當 C6 上(shang)(shang)的(de)(de)額定電(dian)(dian)(dian)壓(ya)(ya)充(chong)至 Z1 的(de)(de)穩壓(ya)(ya)值時(shi) Q2 導 通。一旦 C8 漏電(dian)(dian)(dian)或后(hou)級電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)(lu)燒壞物理(li)現(xian)象，在(zai)起機的(de)(de)畫面瞬時(shi)電(dian)(dian)(dian)流在(zai) RT1 上(shang)(shang)有的(de)(de)壓(ya)(ya)降(jiang)增(zeng)加，Q1 導 通使 Q2 沒得柵極電(dian)(dian)(dian)壓(ya)(ya)降(jiang)不導通，RT1 一定會在(zai)很短(duan)的(de)(de)一直焚毀，以維護保養后(hou)級控制電(dian)(dian)(dian)路(lu)(lu)。
三(san)、 功效改變電路板
1、 MOS 管(guan)的(de)功(gong)課的(de)基(ji)本原理：如今用到范圍(wei)廣泛的(de)絕緣帶柵(zha)場(chang)效用管(guan)是(shi) MOSFET（MOS 管(guan)），是(shi)施用半(ban)導(dao)體技術內心(xin)(xin)的(de)電聲(sheng)負(fu)反(fan)應實現課外作業的(de)。也(ye)是(shi)指(zhi)內心(xin)(xin)場(chang)負(fu)反(fan)應功(gong)率器件。擔心(xin)(xin)它的(de)柵(zha)極正處在不導(dao)電請況， 故此(ci)設置電容能夠(gou)大大大大提升，高(gao)達(da)會達(da) 105 歐姆，MOS 管(guan)是(shi)運用柵(zha)源端電壓(ya)的(de)大小，來替(ti)換(huan)半(ban) 導(dao)身體之外表感生電勢的(de)多少個，但是(shi)調節漏極直流(liu)電壓(ya)的(de)大小。
2、運行目的(de)(de)(de)(de)(de)(de)： R4、C3、R5、R6、C4、D1、D2 組合(he)(he)成抗震器(qi)，和(he)(he)(he)打開MOS 管(guan)(guan)并(bing)接，使面板開關(guan)(guan)管(guan)(guan)端(duan)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)載荷增多， EMI極大減少，不(bu)形(xing)成2次損(sun)壞。在(zai)旋(xuan)鈕(niu)管(guan)(guan) Q1 關(guan)(guan)斷時(shi)，箱式變(bian)壓(ya)(ya)(ya)器(qi)的(de)(de)(de)(de)(de)(de)原邊(bian)電(dian)(dian)(dian)(dian)阻(zu)誘發生尖峰(feng)交流(liu)(liu)(liu)(liu)直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和(he)(he)(he)尖峰(feng)直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，哪(na)些(xie)元器(qi)件樂隊組合(he)(he)一(yi)(yi)起(qi)去，能(neng)更好地融合(he)(he)尖峰(feng)交流(liu)(liu)(liu)(liu)直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和(he)(he)(he)直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)。從(cong) R3 測定的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)值量基線(xian)數(shu)字(zi)信號(hao)報(bao)名參加目前施工周(zhou)波的(de)(de)(de)(de)(de)(de)占空比操作(zuo)(zuo)，之所以是目前施工周(zhou)波的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)值量束縛。當 R5 上的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)提(ti)高(gao) 1V 時(shi)，UC3842 終止英(ying)語作(zuo)(zuo)業，電(dian)(dian)(dian)(dian)開關(guan)(guan)管(guan)(guan) Q1 請馬(ma)上關(guan)(guan)斷。R1和(he)(he)(he)Q1中的(de)(de)(de)(de)(de)(de)結電(dian)(dian)(dian)(dian)阻(zu) CGS、CGD一(yi)(yi)起(qi)來構成 RC 網路(lu)，濾波電(dian)(dian)(dian)(dian)容的(de)(de)(de)(de)(de)(de)充充放直(zhi)(zhi)觀直(zhi)(zhi)接影響著按鈕(niu)按鈕(niu)管(guan)(guan)的(de)(de)(de)(de)(de)(de)按鈕(niu)按鈕(niu)速 度。R1過小，易進(jin)而引發機械(xie)振動，渦流(liu)(liu)(liu)(liu)攪擾(rao)也會很高(gao)；R1過大，會降低啟閉管(guan)(guan)的(de)(de)(de)(de)(de)(de)啟閉效率。Z1 通(tong) 常將 MOS 管(guan)(guan)的(de)(de)(de)(de)(de)(de) GS 的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)限制(zhi)在(zai) 18V下面，最后保護(hu)了(le)(le)(le) MOS 管(guan)(guan)。Q1 的(de)(de)(de)(de)(de)(de)柵極受控電(dian)(dian)(dian)(dian)阻(zu)值為鋸(ju)形(xing)波，當其占空比越大時(shi)，Q1 導通(tong)時(shi)時(shi)刻(ke)(ke)刻(ke)(ke)越長，變(bian)電(dian)(dian)(dian)(dian)器(qi)所存貯的(de)(de)(de)(de)(de)(de)動能(neng)也就越少；當Q1截止日期時(shi)，干(gan)(gan)式變(bian)壓(ya)(ya)(ya)器(qi)要(yao)經過 D1、D2、R5、R4、C3 脫離激光(guang)能(neng)量是什么，一(yi)(yi)并(bing)也達到了(le)(le)(le)了(le)(le)(le)電(dian)(dian)(dian)(dian)場回零的(de)(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(de)，為干(gan)(gan)式變(bian)壓(ya)(ya)(ya)器(qi)的(de)(de)(de)(de)(de)(de)下有一(yi)(yi)次數(shu)據庫、獲(huo)取(qu)激光(guang)能(neng)量是什么要(yao)做(zuo)好了(le)(le)(le)預(yu)備(bei)黨員。IC 合(he)(he)理性(xing)輸(shu)送的(de)(de)(de)(de)(de)(de)交流(liu)(liu)(liu)(liu)交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和(he)(he)(he)直(zhi)(zhi)流(liu)(liu)(liu)(liu)交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)隨時(shi)調(diao) 整著腳鋸(ju)形(xing)波占空比的(de)(de)(de)(de)(de)(de)大小，并(bing)且踏實了(le)(le)(le)機床(chuang)的(de)(de)(de)(de)(de)(de)輸(shu)送的(de)(de)(de)(de)(de)(de)直(zhi)(zhi)流(liu)(liu)(liu)(liu)交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和(he)(he)(he)交流(liu)(liu)(liu)(liu)交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)。C4和(he)(he)(he) R6為尖峰(feng)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)獲(huo)取(qu)二次回路(lu)。
3、一起整流電路系統(tong)：
上(shang)班關鍵技(ji)術：當電(dian)(dian)(dian)(dian)壓器次(ci)級(ji)上(shang)部(bu)為(wei)(wei)正(zheng)時，直流(liu)(liu)電(dian)(dian)(dian)(dian)壓經 C2、R5、R6、R7 使(shi)(shi) Q2 導通，電(dian)(dian)(dian)(dian)路系(xi)統組成(cheng)部(bu)分控制回路， Q2 為(wei)(wei)整流(liu)(liu)管。Q1 柵極(ji)如果是反偏而(er)截止(zhi)到。當干式變壓器次(ci)級(ji)底端(duan)為(wei)(wei)正(zheng)時，感應電(dian)(dian)(dian)(dian)流(liu)(liu)經 C3、R4、R2 使(shi)(shi) Q1 導通，Q1 為(wei)(wei)續流(liu)(liu)管。Q2 柵極(ji)這是因為(wei)(wei)始(shi)終處于反偏而(er)截止(zhi)期。L2 為(wei)(wei)續流(liu)(liu)電(dian)(dian)(dian)(dian)感，C6、L1、C7 組成(cheng)的 π 型濾波器。R1、C1、R9、C4 為(wei)(wei)削尖(jian)峰電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。
五、 穩壓環路(lu)原里
安(an)全作(zuo)業作(zuo)用：當輸出(chu)電(dian)(dian)(dian)(dian)壓(ya) U0 增加，經(jing)送樣功率(lv)電(dian)(dian)(dian)(dian)阻 R7、R8、R10、VR1 分壓(ya)后(hou)(hou)，U1腳(jiao)(jiao)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流增高，當其超過(guo)(guo) U1腳(jiao)(jiao)依(yi)據額定(ding)電(dian)(dian)(dian)(dian)壓(ya)后(hou)(hou) U1腳(jiao)(jiao)所在(zai)高電(dian)(dian)(dian)(dian)平(ping)，使(shi)(shi) Q1 導通(tong)(tong)，光(guang)(guang)耦 OT1 帶光(guang)(guang)肖特基二極管帶光(guang)(guang)，光(guang)(guang)電(dian)(dian)(dian)(dian)晶體管導通(tong)(tong)， UC3842腳(jiao)(jiao)電(dian)(dian)(dian)(dian)位差某些變少，之后(hou)(hou)更新 U1腳(jiao)(jiao)讀(du)取(qu)占空(kong)比縮(suo)減，U0 增漲。 當效果 U0 的(de)降(jiang)低時(shi)，U1腳(jiao)(jiao)電(dian)(dian)(dian)(dian)壓(ya)降(jiang)越(yue)來越(yue)低，當其低過(guo)(guo) U1腳(jiao)(jiao)基準(zhun)(zhun)值(zhi)線電(dian)(dian)(dian)(dian)壓(ya)后(hou)(hou) U1腳(jiao)(jiao)輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)低電(dian)(dian)(dian)(dian)平(ping)，Q1 不(bu)導通(tong)(tong)，光(guang)(guang)耦 OT1 會(hui)亮場效應管不(bu)會(hui)亮，光(guang)(guang)學三級管不(bu)導通(tong)(tong)，UC3842腳(jiao)(jiao)電(dian)(dian)(dian)(dian)極電(dian)(dian)(dian)(dian)位偏高，并且變動(dong) U1腳(jiao)(jiao)輸出(chu)占空(kong)比過(guo)(guo)大，U0 急(ji)劇下降(jiang)。無限(xian)循環(huan)循環(huan)往(wang)復，以后(hou)(hou)使(shi)(shi)打出(chu)的(de)電(dian)(dian)(dian)(dian)壓(ya)要保持安(an)逸。冶療 VR1 可變動(dong) 輸出(chu)精(jing)度(du)交流的(de)電(dian)(dian)(dian)(dian)壓(ya)交流的(de)電(dian)(dian)(dian)(dian)壓(ya)值(zhi)。 的(de)現(xian)象(xiang)環(huan)路(lu)是會(hui)影響面板開關(guan)的(de)電(dian)(dian)(dian)(dian)壓(ya)準(zhun)(zhun)確性的(de)必要電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路(lu)。如的(de)現(xian)象(xiang)阻值(zhi)電(dian)(dian)(dian)(dian)容（電(dian)(dian)(dian)(dian)容器(qi)）錯、漏、虛焊等(deng)，會(hui)有自(zi)激 機械(xie)噪聲，出(chu)毛病的(de)現(xian)象(xiang)為：波形圖非(fei)常，空(kong)、載(zai)滿機械(xie)噪聲，輸出(chu)精(jing)度(du)交流的(de)電(dian)(dian)(dian)(dian)壓(ya)交流的(de)電(dian)(dian)(dian)(dian)壓(ya)不(bu)準(zhun)(zhun)確等(deng)。
六、擊穿(chuan)維修(xiu)用電線路：
1、在輸(shu)送端過壓的癥狀下:
PWM 操縱電線能能把打出(chu)工作電流(liu)管(guan)束在同一個人身安(an)全空間(jian)內(nei)，它(ta) 能能用(yong)多樣(yang)技(ji)巧來做完限(xian)流(liu)電線，當電機(ji)功(gong)率限(xian)流(liu)在斷路時(shi)我用(yong)途(tu)時(shi)，不過另加建一環節分(fen)電線。
2、短(duan)路(lu)故障(zhang)等問題維持用電(dian)(dian)線路(lu)似的(de)有(you)三種(zhong)，其(qi)基本原理闡述(shu)下面的(de)：當(dang)輸(shu)出(chu)用電(dian)(dian)線路(lu)短(duan)路(lu)故障(zhang)等問題，輸(shu)出(chu)的(de)電(dian)(dian)壓(ya)(ya)熄(xi)滅，光耦 OT1不導(dao)通，UC3842腳相電(dian)(dian)壓(ya)(ya)上漲(zhang)至 5V 左右兩邊，R1 與(yu) R2 的(de)分(fen)壓(ya)(ya)勝過 TL431 系數，使(shi)之導(dao)通，UC3842腳 VCC 電(dian)(dian)極電(dian)(dian)位(wei)被會(hui)降低，IC 暫緩功課(ke)。UC3842 休庭(ting)施工作(zuo)(zuo)業后(hou)腳電(dian)(dian)勢差沒有(you)，TL431不導(dao)通 UC3842腳電(dian)(dian)位(wei)差增漲(zhang)，UC3842 再(zai)次起動，重復往返。當(dang)短(duan)路(lu)故障(zhang)現(xian)況(kuang)沒了(le)后(hou)，電(dian)(dian)路(lu)板(ban)不錯半(ban)自(zi)動康復訓練(lian)成一切正常課(ke)外作(zuo)(zuo)業現(xian)況(kuang)。
3、如圖是中耗油率短路故障定期維護三極管，其(qi)目的簡析給出：
當讀取短(duan)路(lu)故障，UC3842腳(jiao)電(dian)(dian)(dian)(dian)阻變高(gao),U1腳(jiao)電(dian)(dian)(dian)(dian)極電(dian)(dian)(dian)(dian)勢(shi)超出(chu)腳(jiao)時，更加器轉(zhuan)動腳(jiao)導出(chu)高(gao)電(dian)(dian)(dian)(dian)極電(dian)(dian)(dian)(dian)勢(shi)，給C1電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)，當 C1 兩手輸出(chu)功(gong)率戰勝腳(jiao)系(xi)數(shu)輸出(chu)功(gong)率時 U1腳(jiao)內(nei)容輸出(chu)低電(dian)(dian)(dian)(dian)極電(dian)(dian)(dian)(dian)位，UC3842腳(jiao)小(xiao)于1V，UCC3842 執行程序高(gao)空作業，輸出(chu)精度工作電(dian)(dian)(dian)(dian)壓為 0V，循環法循環往復(fu)，當出(chu)現短(duan)路(lu) 消失掉后電(dian)(dian)(dian)(dian)線沒問題做業。R2、C1是充電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)隨時常數(shu)，阻值不合適時不導通運(yun)營維護不起來(lai)用。
4、常見(jian)的(de)的(de)限(xian)流、斷路保養集成運放。
其家庭作業機(ji)制詳述以(yi)下： 當轉換電(dian)(dian)路(lu)設計(ji)串電(dian)(dian)或過流，配(pei)電(dian)(dian)變壓(ya)器原邊電(dian)(dian)流量變高，R3 兩邊電(dian)(dian)阻值(zhi)降大(da)，腳(jiao)電(dian)(dian)阻值(zhi)增加，UC3842腳(jiao)輸(shu)出(chu)占空(kong)比迅速提高，腳(jiao)的電(dian)(dian)壓(ya)掌控(kong) 1V 時，UC3842關閉程(cheng)序(xu)無輸(shu)出(chu)的。
5、用水量流互(hu)調節器取(qu)樣方法功(gong)率的系統維護電路(lu)系統，
存在功能損(sun)耗小(xiao)，但利潤高和電源線(xian)路相對冗雜，其做業機制(zhi)舉例說明以下：
所在電線發生故障或工(gong)作電流過(guo)大，TR1 次(ci)級(ji)電磁鐵自(zi)感應的電壓電流就(jiu)越高，當UC3842腳撼(han)動1伏(fu)，UC3842 駁回操(cao)作，無限循環往返(fan)，當短路故障或過(guo)載保護消(xiao)掉，集成(cheng)運放立(li)刻康服。
