LLC (ʻelua inductors a me hoʻokahi capacitor topology) Transformer
Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomohala ʻana i ka ʻenehana uila, ʻoi aku ka nui o nā mea uila e koi ai i ka hoʻohana ʻana i nā ʻāpana transformer.ʻO nā mea hoʻololi LLC (resonant), me ko lākou hiki ke hana i ka manawa like me ka ʻole o ka ukana a hōʻike i ka māmā a i ʻole ka ukana kaumaha me ke kahawai resonant i kēia manawa, e hoʻokomo i nā pono i hiki ʻole i nā mea hoʻololi resonant maʻamau a me nā mea hoʻololi resonant like ke hoʻohālikelike, no laila, ua hoʻohana nui ʻia lākou.
ʻO ka LLC transformer kahi hoʻomaikaʻi i ka LC kuʻuna lua-kaupapa resonant transformer ma o ka hoʻohui ʻana i kahi inductor like.Loaʻa iā ia nā mea maikaʻi o ke alapine hoʻololi kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ākea ākea ākea hoʻokomo uila, hana kiʻekiʻe, paona māmā, haʻahaʻa haʻahaʻa EMI, a haʻahaʻa hoʻololi koʻikoʻi.Eia nō naʻe, i ka emi ʻana o ka wahi hoʻonohonoho, aia kahi koi kiʻekiʻe no ka nui o ka mea hoʻololi LLC.
ʻO ka mea hoʻololi LLC i hana ʻia e Yamaxi, koe wale nā mea maikaʻi i ʻōlelo ʻia ma luna, he liʻiliʻi ka liʻiliʻi a me ka mana kiʻekiʻe, no laila me ka mana kiʻekiʻe.Eia kekahi, he kiʻekiʻe ka pololei o ka leakage inductance, hilinaʻi kiʻekiʻe, kūpaʻa kiʻekiʻe a me ke kūpaʻa kiʻekiʻe.Hōʻike ʻia nā pōmaikaʻi kikoʻī ma lalo nei:
(1) Hiki ke hoʻomalu i ka leakage inductance i loko o 1% -10% o ka inductance nui;Hiki ke mālama ʻia ka leakage ma 5%
(2) Loaʻa i ka magnetic core ka hoʻohui electromagnetic maikaʻi, ka hana maʻalahi a me ka hana kiʻekiʻe;
(3) Ke alapine hana kiʻekiʻe, ka mana kiʻekiʻe, ke alapine ma waena o 50kHz ~ 300kHz.
(4) ʻO nā hiʻohiʻona hoʻoheheʻe wela maikaʻi loa, me kahi kiʻekiʻe o ka ʻili a me ka ratio leo, kahi ala wela pōkole loa, kūpono no ka hoʻopau wela.
(5) Hiki ke hoʻohaʻahaʻa maikaʻi i ka poho kumu (5) ʻo ke ʻano magnetic core o ke ʻano geometric kūikawā.
(6) Liʻiliʻi electromagnetic radiation interference.Haʻahaʻa mana poho, haʻahaʻa wela piʻi, kiʻekiʻe pono
◆ ʻO ka hilinaʻi kiʻekiʻe, e hoʻokō me AEC-Q200;
◆ Haʻahaʻa poho;Kiʻekiʻe Power Density, Hoʻopau wela maikaʻi;
◆ Hiki ke kiʻi i ka wela hana ma 140 ℃;
◆ ʻAha haʻahaʻa haʻahaʻa leaka inductance (0.1uH Max.)
Kaʻa a me ka papa mana kikowaena.Kūpono loa no nā noi ma kekahi mau lako mana kūpono a kiʻekiʻe.
