Lero tikuwunika momwe ntchito yoyendera dera la inductor ikugwiritsidwa ntchito, m'dera lenilenili makamaka kugwiritsa ntchito ma inductors kudzera pakukana kwapafupipafupi kumayendedwe apamwamba, kudzera kukana kwa DC kumayendedwe a AC pamapangidwe a mabwalo osiyanasiyana, kutsatira tiyang'ana pa inductor mu DC-DC boost circuit mfundo ntchito.

1. Kusintha S kwatsekedwa:

Monga momwe tawonetsera mu Chithunzi 1, pamene kusintha kwa S kutsekedwa, a, b, d amapanga chipika chotsekedwa, mphamvu yamagetsi E kupyolera mu inductor imapanga yaing'ono mpaka yaikulu panopa i, panthawiyi t1 (monga Chithunzi 2 t1 → t2 ) ma frequency apano amakhala pafupi ndi ma frequency apamwamba, molingana ndi lamulo la corrugator (kuwonjezera anti-kuchepa komweko), inductor imapanga induced current motsatira njira yosiyana ndi yoyambira pano i, yomwe imapangitsa kuti pakhale kusintha. i, inductor inachititsa njira yamakono ya b → a, zomwe zikutanthauza kuti mphamvu yamagetsi yomwe ilipo panopa i mu inductor mu mphamvu ya maginito yosungidwa mpaka t2 pamene yamakono ndi yaikulu, mphamvu yolepheretsa imakhalanso yaikulu, mphamvu ya maginito yosungidwa. mu inductor ndi waukulu kwambiri. Ndiye t2 pambuyo pakalipano imakhala yosalala, mafupipafupi omwe alipo tsopano amakhala ku DC, kutsekeka kwa inductor kumafowoka, kuwonjezereka kwamakono kupyolera mu kusintha, kupangidwa kwa kuzungulira kotsekedwa kumayenda kumtunda woipa.Mndandanda wazinthu zonsekuti agwiritsidwe ntchito mu ma circuit DC-DC.

2. Sinthani S kulumikiza:

Monga momwe tawonetsera mu Chithunzi 3, pamene kusintha kwa S kutsekedwa, a, b, d sikupanga chipika chotsekedwa, mphamvu yamagetsi E imayenda kupyolera mu inductor panopa nthawi yomweyo kuchokera ku inductor wamkulu, panthawiyi t3 (monga chithunzi 4). t3 → t4) ma frequency apano amakhala pafupi ndi ma frequency apamwamba, molingana ndi lamulo la corrugator (onjezani anti-kuchepa komweko), inductor imapanga inductive current motsatira njira yofanana ndi yoyambira pano i, yomwe idapangidwa panopa. zimandilepheretsa kusintha, mayendedwe a inductor omwe amapangidwira panopa kwa a → b, zomwe zikutanthauza kuti magetsi Panopa mu inductor adzakhala atatembenuza mphamvu ya maginito inayamba kusinthidwa kukhala yamakono, mayendedwe amakono kupyolera mu diode a → b → c → d, mwachitsanzo, voteji pamalo b kwa inductor anachititsa electromotive mphamvu e kuphatikiza choyambirira mphamvu magetsi voteji E, iwo ali pamodzi kudzera diode D1 ndi capacitance C kulipiritsa kusungidwa, ndipo nthawi yomweyo, linanena bungwe. voteji pa katundu U0, ngati simuganizira kutsika kwa magetsi a diode, U0 = E + e. zomwe zidapangitsa kuti votejiyo iwonetsedwe ndi kukula kwa fomula A: Fomula iyi ikuwonetsa kuti kukula kwa voteji ndi kukula kwa inductance, kuchuluka kwa kusintha kwapano pa nthawi ya unit kumatha kufufuzidwa mopitilira muyeso wathu.New Centerkwa chidziwitso chaukadaulo.

Choncho pa nthawi imeneyi voteji U0 ndi apamwamba kuposa kotunga voteji E. Mpaka t2 pamene panopa ine ndi ang'onoang'ono, chotchinga mphamvu ndi yaing'ono kwambiri, mphamvu maginito kusungidwa mu inductor nawonso kwenikweni mofulumira kutembenuka mapeto. Kenako, kudzera pa switch nthawi zonse kutsekedwa, kulumikizidwa, mutha kutulutsa voteji U0 nthawi zonse, ndipo voteji U0 ndi yayikulu kuposa mphamvu yamagetsi E, kuti muyimbe cholinga chokulitsa.
