YINTONI ITSHINTSHI YESIBONELELO SAMANDLA OKUTSHINTSHA?ISEBENZA NJANI?

Ukutshintsha i-transformers kuyafuneka ekutshintsheni izixhobo zombane.Ngoko ke yintoni i-switching transformers?Yiyiphi imigaqo yokusebenza kunye nemisebenzi yokutshintsha iinguqu?Masiziqonde.

 

·Intshayelelo

I-transformer yokutshintsha ibhekisela kwi-transformer esetyenziswe kwi-switching power supply.Isebenza kwisimo sokubetha kwentliziyo ngokuphindaphindiweyo kweshumi ukuya kwamashumi ekhilohertz okanye namakhulu ekhilohertz.I-iron core yenziwe ngokubanzi ngezinto ze-ferrite.

           

·Umgaqo wokusebenza wokutshintsha i-transformer

I-transformer sisixhobo sombane esenziwe kusetyenziswa umgaqo wokungeniswa kwe-electromagnetic.Xa i-coil ephambili ye-transformer ixhunywe kumthombo wamandla we-AC, i-iron core ivelisa i-alternating magnetic flux.Ukunikezelwa kwamandla okutshintsha kulawulwa yisekethe, kwaye i-tube yokutshintsha itshintshi ngesantya esiphezulu.

Ukuguqulwa kwangoku ngokuthe ngqo ukuya kwi-high frequency alternating current inikezelwa kwi-transformer yokuguqulwa, ngaloo ndlela ivelisa isethi enye okanye ngaphezulu kwee-voltages.Ekubeni ukusebenza kwe-AC frequency ephezulu kwi-transformer circuit iphezulu kakhulu kune-50Hz, zonke iinguqu zokutshintsha zingenziwa zincinci kakhulu, ngaloo ndlela zinciphisa iindleko.

 

·Tindima yakhe yokutshintsha ii-transformers

Imisebenzi ephambili yokutshintsha i-transformers kukuhanjiswa kwamandla, ukuguqulwa kwe-voltage kunye nokugquma.

Iingenelo zayo eziphambili bubukhulu obuncinci, ukusebenza kakuhle okuphezulu, kunye nokolula ngexabiso eliphantsi.Njengenxalenye enkulu yemagnethi yemagnethi ethambileyo, iziguquli zokutshintsha zisetyenziswa kakhulu ekutshintsheni itekhnoloji yobonelelo lwamandla kunye netekhnoloji yombane we-elektroniki, kwaye zikwasetyenziswa kwiisekethe ezijikelezayo ezinjengokutshintsha umbane.

 

Ngokwamandla okuhanjiswa kwe-transformer switching, abaguquli bamandla banokuhlulwa ngamabakala amaninzi: i-10kVA inamandla amakhulu, i-10kVA ~ 0.5kVA inamandla aphakathi, i-0.5kVA ~ 25VA inamandla aphantsi, kwaye ngaphantsi kwe-25VA inamandla amancinci.Amandla othumelo ahlukeneyo, uyilo lwe-transformer yamandla lukwahlukile.Undoqo we-ferrite kunye ne-magnetic saturation coefficient yesiguquli samandla ayilunganga njengaleyo ye-silicon steel sheet core, ekhokelela kumandla amancinci kakhulu kwi-Hertz yokudluliselwa kwamandla e-AC.Kodwa usebenza kwi-high-frequency circuit, kunye ne-energy exchange frequency per unit time interval iphezulu kakhulu (i-1000 times that of a low-frequency transformer).Ithatyathwe kunye, ukusebenza kwayo kunokufikelela kumatyeli aphindwe kabini kunalawo aguquguqukayo asezantsi.

 

·Omnye umsebenzi we-switching transformer kukuba unempendulo ejikelezayo

I-feedback winding inika umqondiso wempendulo efanelekileyo kwi-PWM IC, ibangela ukuba ivelise i-oscillation ephezulu-frequency kunye ne-secondary winding, ukwenzela ukuba i-DC ingena kwi-primary winding ye-transformer inecandelo elikhulu le-AC, kunye ne-AC ephezulu. icandelo lodwa ngundoqo we-transformer, okwenza i-secondary Pure high-frequency AC, elungiswayo kwaye ihluzwe ukubonelela ngezixhobo zombane.I-feedback winding inokulungelelanisa i-voltage ephumayo kwixabiso elizinzile.Ukushwankathela, i-transformer yokutshintsha idlala indima yokuhanjiswa kwamandla, ukuguqulwa kwe-voltage kunye nokufakelwa.
