Ingundoqo ye-flyback transformer yi-inductor edibeneyo, kwaye ukugcinwa kunye nokukhululwa kwamandla kuqhutyelwa ngokuhlukileyo.
Inkqubo eqhelekileyo ye-inductor esetyenziswa njengendawo yokugcina amandla kukuvula isithuba somoya.I-Flyback transformers ayinjalo.
Isiphumo sokuvula isikhewu somoya siphindwe kabini:
I-1) Lawula i-inductance, i-inductance efanelekileyo inokuhlangabezana neemfuno zoyilo.
I-inductance inkulu kakhulu kwaye amandla akakwazi ukubizwa.Ukuba i-inductance incinci kakhulu, uxinzelelo lwangoku lwe-tube yokutshintsha luya kwanda.
2) Nciphisa ukuxinana kwemagnethi
Ukucinga ukuba i-inductance, i-current and magnetic material iye yamiselwa, ukwandisa i-gap yomoya kunokunciphisa ubuninzi bokusebenza kwe-inductor ukukhusela ukugcwala.
Emva kokuqonda umsebenzi wokuvula i-gap yomoya, makhe sibone ukuba kukho i-flyback transformer engayivuli isithuba somoya?
Impendulo kukuba ngokwenene akukho msantsa womoya.Kukho malunga neemeko ezintathu apho umsantsa womoya kungafuneki ukuba uvulwe.
A. Undoqo wemagnethi okhethiweyo mkhulu kakhulu kunemfuno yokwenyani.
Masithi wenze isiguquli se-1W kwaye ukhethe i-EE50 engundoqo, ngoko ke ukugcwala kwayo okunokwenzeka ngu-zero.
Akukho mfuneko yokuvula isithuba somoya.
B. I-powder core material magnetic ikhethiwe, kuquka i-FeSiAl, i-FeNiMo kunye nezinye izinto.
Ngenxa yokuba i-powder core imathiriyeli yemagnethi ivumela ukuxinana kwemagnethi esebenzayo ukufikelela kwi-10,000, ephezulu kakhulu kune-3,000 ye-ferrite eqhelekileyo.
Emva koko ngokubala okufanelekileyo, akukho mfuneko yokuvula i-gap yomoya kwaye ayiyi kuhluthwa.Ukuba ubalo alwenziwanga kakuhle, lusenokuba lugcwele.
C. Iimpazamo zoyilo okanye iimpazamo zokuqhuba.
