Ungayilungisa kanjani i-pulse transformer esithandweni sokuncibilika se-induction?

Kungakhathaliseki ukuthi ukushaya kwe-rectifier (ama-pulse transformer amancane angu-6 ebhodini lokulawula) noma i-inverter pulse (efakwe kwenye indawo, kuye ngokuthi i-pulse pulse transformer esetshenziswa ukuchithwa kwesithando somlilo umkhiqizi, kukhona i-transformer eyodwa noma ama-transformer amabili ndawonye. Kumabhodi amancane wesifunda, kukhona ama-transformer angu-4 ebhodini elilodwa lesifunda). Kodwa kukhona i-diode ekhipha ukukhanya ebomvu noma eluhlaza ohlangothini lwe-transformer ngayinye. Lapho ukushaya kwenhliziyo kuyinto evamile, lawa ma-diode azokhipha ukukhanya. Yiqiniso, ngezinye izikhathi i-diode ekhipha ukukhanya ngokwayo iphukile.

Ngakho-ke ingabe kuqinisekile ukuthi ama-diode akhipha ukukhanya avuliwe ukuze abonise ukuthi ukushaya kwenhliziyo kujwayelekile? impendulo ithi negative. Ingxenye ephumayo yamanye amasekhethi okushaya kwenhliziyo ifakwe ama-diode amabili, eyodwa ifana nokulungiswa kwamagagasi ohhafu ukuze kunikeze amandla ogesi wokuqhumisa phambili ku-thyristor, kanti enye ihlehliswa futhi ixhunywe kutheminali yokukhiphayo ukuze kukhawulwe ukuphuma kwamandla kagesi amaningi. Ngokucabanga ukuthi i-diode yangaphambilini esetshenziselwa ukulungiswa iphukile (isifunda esivulekile), i-voltage-limiting diode iyalungiswa, futhi i-diode ekhipha ukukhanya isakhipha ukukhanya uma ine-voltage eya phambili. Ngakho-ke, i-diode ekhipha ukukhanya ayikwazi ukucacisa ngokunembile ukuthi i-pulse transformer yonakalisiwe.

Endabeni yokuhlola ubuqotho bezinye izingxenye (ikakhulukazi i-thyristors), indlela yokwahlulela ukuthi i-rectifier pulse inhle noma cha: susa intambo evamile yezintambo ezintathu ze-inverter pulse ebhodini lokulawula. Ebhodini lokulawula uhlobo lwe-MPU-2, Vula iswishi encane No. 1 ebhodini uye kolunye uhlangothi (cisha isekethe yokushanela), bese uvula amandla kagesi aphakathi nendawo ngokohlelo, vula i-potentiometer yamandla iphaneli yomnyango ukuya phezulu, bese ubheka ukuthi i-voltage ye-DC ingu-400 ~ 500V? Uma kunjalo, kusho ukuthi i-rectifier circuit kuhlanganise ne-rectifier pulse ngokuyisisekelo ijwayelekile; uma i-voltage ye-DC ingajwayelekile noma iphansi kakhulu, susa amasango e-thyristor yokulungisa elinye ngalinye bese ubheka. Khumbula, uma i-thyristor ene-pulse evamile isusiwe, I-voltage izoba ngaphansi. Uma i-thyristor eyonakaliswe yi-pulse isusiwe, ayikho impendulo kumitha, njengokungathi ucingo alususiwe, kusho ukuthi kunenkinga nge-pulse ehambisanayo. Susa ibhodi le-pulse, uma kukhona ama-diode amabili ekugcineni kokuphuma kwebhodi lokushaya kwe-pulse, solder ekupheleni kwe-diode elandelayo, bese ulinganisa ukumelana kwemitha yendawo yonke, bese ubuyisela ephukile.
