DC (Direct Current) Sinthani kukhala DC Transformer
Transformer ya DC/DC ndi gawo kapena chipangizo chomwe chimatembenuza DC (mwachindunji) kukhala DC, makamaka kutengera gawo lomwe limagwiritsa ntchito DC kutembenuza kuchokera mulingo wina wamagetsi kupita kumagetsi ena.DC/DC imagawidwa m'magulu awiri kutengera kusintha kwa magetsi: Transformer yomwe imapanga magetsi otsika kuposa magetsi oyambirira amatchedwa "step-down transformer";Transformer yomwe imapanga magetsi apamwamba kuposa magetsi oyambirira amatchedwa "boost transformer".Ndipo imathanso kugawidwa m'magulu amagetsi akutali komanso magetsi osadzipatula kutengera kulumikizana / kutulutsa.Mwachitsanzo, chosinthira cha DC/DC cholumikizidwa ndi magetsi agalimoto a DC chimasintha ma DC wokwera kwambiri kukhala DC wocheperako.Ndipo zida zamagetsi monga ma IC zili ndi magawo osiyanasiyana ogwiritsira ntchito magetsi, motero zimafunikanso kusinthidwa kukhala ma voltages ofanana.
Makamaka, zimatanthawuza kutembenuza zolowetsa za DC kukhala AC kudzera mu Self-oscillation circuit, kenako kusinthira ku DC kutulutsa mutatha kusintha voteji kudzera pa thiransifoma, kapena kutembenuza AC kukhala yotulutsa mphamvu yamagetsi ya DC kudzera pamagetsi owirikiza kawiri.
Ubwino watsatanetsatane wawonetsedwa pansipa:
(1) Kutulutsa kotayirira kumatha kuwongoleredwa mkati mwa 1% -10% ya inductance yayikulu;
(2) Maginito pachimake ali wabwino maginito coupling, kapangidwe yosavuta ndi mkulu dzuwa;
(3) High ntchito pafupipafupi, mkulu mphamvu kachulukidwe, pafupipafupi pakati za 50kHz ~ 300kHz.
(4) Makhalidwe abwino kwambiri otenthetsera kutentha, okhala ndi malo okwera kwambiri mpaka kuchuluka kwa voliyumu, njira yayifupi kwambiri yotenthetsera, yabwino kutulutsa kutentha.
(5) Kuchita bwino kwambiri, mawonekedwe apakati a maginito a mawonekedwe apadera a geometric amatha kuchepetsa kutayika kwakukulu.
(6) Kusokoneza kwamagetsi kwamagetsi kakang'ono.Kutsika kwamphamvu kwamphamvu, kukwera kotsika kwa kutentha, kutentha kwambiri.
1. Ali ndi machulukitsidwe apamwamba maginito induction;
2. Kutentha kwapamwamba kwa Curie, kuchepa kwachitsulo chochepa komanso kukakamiza;
3. Kutentha kwabwino kwa kutentha, phokoso lochepa komanso kuyendetsa bwino;
4. Kusalowetsedwa kwa madzi, chinyezi, fumbi komanso kugwedezeka;
5. Kuchulukana kwamphamvu kwamphamvu;
6. Kulondola kwakukulu kwa kutayikira kwa inductance;
7. Kudalirika kwakukulu, kukhazikika kwakukulu, kusasinthasintha kwakukulu;
