Sidee loo dayactiraa transformer-ka garaaca wadnaha ee foornada dhalaalidda induction?

Haddi ay tahay garaaca garaaca garaaca wadnaha (6 Transformer pulse yar ee sabuuradda kontoroolka) ama garaaca garaaca garaaca wadnaha (meel kale lagu rakibay, iyadoo ku xidhan pulse pulse transformer-ka uu isticmaalo foornada dhalinta dhalaalaysa soo saaraha, waxaa jira hal transformer ama laba transformer oo wada jira. Looxyada yaryar ee wareegga, waxaa jira 4 transformers oo ku yaal hal sariirood). Laakin waxaa jira diode casaan ama cagaar ah oo soo baxaya dhinaca transformer kasta. Marka garaaca garaaca wadnaha uu yahay mid caadi ah, diode-yadani waxay soo daayaan iftiin. Dabcan, mararka qaarkood diode iftiin-bixiya laftiisa ayaa jaba.

Markaa ma la hubaa in diodh-yada iftiimiya ay shidan yihiin si ay u muujiyaan in garaaca wadnaha uu yahay mid caadi ah? jawaabtu waa taban. Qaybta wax soo saarka ee wareegyada garaaca wadnaha qaarkood waxay ku qalabaysan yihiin laba diodes, mid waxay la mid tahay hagaajinta mawjada nuska si ay u bixiso kicinta hore ee thyristor, kan kalena waa rogan yahay oo ku xiran yahay terminaalka wax soo saarka si loo xaddido wax soo saarka tamarta xad-dhaafka ah. Haddii aan ka soo qaadno in diode-kii hore ee loo isticmaali jiray sixid uu jabay (open circuit) , waxaa dib loo saxayaa diode-ka korantada xaddidaya, iyo diode-ka iftiimiya iftiinka marka uu leeyahay koronto hore. Sidaa darteed, diode iftiin-bixiya si sax ah uma go’aamin karo haddii beddelka garaaca wadnaha uu dhaawacmay.

Xaaladda hubinta daacadnimada qaybaha kale (inta badan thyristors), habka lagu xukumo in garaaca garaaca wadnaha uu fiican yahay iyo in kale: ka saar siliga caadiga ah ee saddexda fiilooyinka garaaca wadnaha ee ku yaala guddiga xakamaynta. Boodhka kantaroolka nooca MPU-2, u leexi bakhtiga yar ee lambarka 1 ee sabuuradda dhinaca ka soo horjeeda (dami wareegga xaaqidda), ka dibna shid tamarta inta jeer ee dhexdhexaadka ah sida ku cad barnaamijka, u rog potentiometer awoodda Albaabka albaabka ilaa ugu badnaan, oo fiirso in danabku DC uu yahay 400 ~ 500V? Haddii ay tahay, waxay ka dhigan tahay in wareegga rectifier oo ay ku jiraan garaaca garaaca wadnaha uu asal ahaan caadi yahay; Haddii danabka DC uu yahay mid aan caadi ahayn ama aad u hooseeya, ka saar albaabbada thyristor-ka toosiyaha mid mid oo u fiirso. Xusuusnow, haddii thyristor leh garaaca wadnaha caadiga ah laga saaro, danabku wuu yaraan doonaa. Haddii thyristor ee garaaca garaaca garaaca la saaro, ma jiraan wax jawaab ah oo ku saabsan mitirka, sida haddii fiilada aan la saarin, waxay la macno tahay in ay jirto dhibaato garaaca wadnaha u dhigma. Ka saar guddiga garaaca wadnaha, haddii ay jiraan laba diode ee dhamaadka wax soo saarka ee guddiga garaaca wadnaha, alxanka hal daraf ee diode soo socda, ka dibna ku cabbir caabiga mitir caalami ah, oo beddelo mid jaban.
