Dulmar guud oo kooban oo ku saabsan 'Triacs' - Qalab Xakamaynta Awoodda AC
Ku Saabsan Triacs Qaybaha Elektarooniga ah iyo Rangegiisa Wax Soo Saarka:
Aaladda loo yaqaan 'triacs' waa aaladda wax lagu gudbiyo ee AC, waxaana laga yaabaa in loo maleeyo inay yihiin laba nooc oo isugeyn ah oo loo yaqaan 'thyristors' oo si monolithically ah loogu daro isla chipon chip isku mid ah. TRIAC, oo ka socota Triode for alternating current, waa magac guud oo ganacsi oo loogu talagalay walxaha elektarooniga ah ee ku dhaqmi kara hada labada dhinacba marki ay kiciyaan, waxaana si rasmi ah loogu magacaabaa bidirectional triode thyristor ama seddexda geesood thyristor. TRIACs waa qayb ka mid ah qoyskaaga 'thyristor' waxayna xiriir dhaw la leeyihiin silsiladaha xakameynaya silikon (SCR), si ka duwan SCRs, kuwaas oo ah aalado aan habooneyn (waxay hadda ku wadi karaan hal jiho oo keliya), TRIACs waa kuwo ku meel gaadh ah sidaas darteedna hadda waxay ku socon karaan labada dhinacba. Farqiga kale ee ka yimaadda SCRs waa in socodka hadda socda ee 'TRIAC' ay awood u yeelan karto mid taban ama mid taban oo hadda lagu dabaqay korantadiisa albaab, halka SCR-yada kaliya lagu kicin karo marka ay hadda soo galaan iridda. Si loo abuuro isbeddel keenaya hadda, korantada togan ama taban waa in laga dalbadaa irridda marka loo eego MT1 Terminalka (haddii kale loo yaqaan A1). Marka uu kiciyo, aaladda waxay sii wadaysaa in ay ku dhaqaaqdo illaa inta ay ka hoos marayso dariiqa cayiman oo loo yaqaan xajinta hadda.
Jihada ayaa ka dhigaysa TRIACs wareejinno aad u habboon oo loogu beddelayo wareegga hadda jira, sidoo kale waxay u oggolaaneysaa inay xakameyso awood aad u ballaaran oo leh albaabo cabbir ballaaran oo cabbir leh.
Ku istcimaalida garaaca halbawlaha wejiga la xakameynayo ee wareegga AC waxay u oggolaaneysaa xakameynta boqolkiiba boqolkiiba ee hadda ku qulqulaya TRIAC illaa culeyska (xakameynta wejiga), kaas oo sida caadiga ah loo isticmaalo, tusaale ahaan, xakameynta xawaaraha soo galinta awoodda hoose. matoorrada, laambadaha daciifka ah, iyo xakameynta qalabka kululeeyeyaasha AC. Sida iska cad waxa kale oo lagu soo kicin karaa iyadoo la dhaafo jebinta qiyaasta korantada. Tan caadi ahaan looma adeegsado hawlgallada Triacs. Goynta korantada ayaa inta badan loo tixgeliyaa inay tahay xaddididda naqshada. Mid kale oo xaddidan oo weyn, sida SCR ah, waa dV / dt, oo ah heerka sare u kaca korantada marka loo eego waqtiga. Aaladda loo yaqaan 'triac' waxaa loo rogi karaa qulqulka dV / dt ballaaran. Codsiyada caadiga ah waxay ku jiraan gacanta marxaladda, naqshadeynta wareejinta, AC beddelashada, dib u gudbinta bedelka. Markii loo isticmaalo culeysyada tamarta leh sida taageerayaasha korantada, waa in taxaddar la muujiyo si loo hubiyo in TRIAC ay si saxan u dammi doonto dhammaadka wareeg kasta ee awoodda AC. Runtii, TRIACs waxay noqon karaan kuwo aad u xasaasi ah oo qiimahoodu sarreeyo ee dv / dt u dhexeeya MT1 iyo MT2, sidaa daraadeed wajiga wareega oo udhaxeeya hada iyo koronto (sida kiiska culeyska) hab aan loo baahnayn.
Qiimaynta iyo astaamaha saddex-geesoodku waxay la mid yihiin kuwa taangigaaga, marka laga reebo in saddex-geesku uusan lahayn wax ku-habboonaynta korantada (korantada ku jirta hal rubuc qabad waa korantada hore ee rubuca ka soo hor jeeda). Si kastaba ha noqotee, hal dabeecad ayaa u baahan taxaddar gaar ah marka la dooranayo seddexleyda; heerka qiyaasta dib-u-adeegsiga korantada ee triacs-yada ay u adkeysan doonaan iyadoo aan la-wareejin aan la xakameyn. Haddii aaladda laydhka lagu xiro iyadoo si dhaqso leh loogu weecinayo korantada sahayda, hadda soo kabashada aaladda ee qalabka waxay si fudud u rogaysaa tan jihada ka soo horjeedda. Si loo dammaanad qaado dhimista hadda ka hooseysa qiimaheeda heysata, korantada sahayda waa in loo yareeyaa eber halkaasna lagu hayaa muddo ku filan si loogu oggolaado dib-u-soo-deynta kharash kasta oo lagu keydiyo aaladda.
