Te Wetewete i ngā Pūnga Totoka ESR Iti a YMIN: Mai i ngā Painga Tawhā ki te Mahi o te Ao Tūturu, Me pēhea te "Whakamatao me te Whakapai ake i te Whai Huatanga" i roto i te Hoahoa Pūtake Hiko?

Kupu Whakataki

E ngā kaihanga hiko, kua pāngia koe e te nui o te ngaru me te werawera o ngā pūnga hiko i a koe e rapu ana i ngā tauira? Ina koa i roto i te whai i te kiato mana teitei o ēnei rā, kua noho te kaha o te ESR me te ia o te ngaru o ngā pūnga hei arai kore e kitea hei whakatau i te angitu, i te kore rānei o te hoahoa. Ka tangohia e tēnei tuhinga te raupapa VPX/VPT a YMIN hei tauira mō tētahi tātaritanga hangarau hōhonu, e whakaatu ana me pēhea te whakaoti i ēnei raruraru me ngā raraunga tūturu.

Te Otinga me ngā Painga a YMIN

Hei tauira, he utu tere 65W 2C2A GaN noa, me whakahaere e ia ngā auau whakawhiti tae atu ki ngā rau kHz i roto i tētahi wāhi kuiti. Mēnā ka whakamahia ngā pūnga totoka noa (ESR tata ki te 40mΩ), kaua e whakaititia ō rātou mate i ngā auau teitei. Kua kite mātou i raro i te putanga kawenga katoa, ka taea e te pāmahana matua o aua pūnga te neke ake i te 85℃, ehara i te mea he mōrearea haumaru wera anake engari ka puta hoki te pirau o te kaha me te pikinga o te ESR nā te pāmahana teitei, ka ara ake ngā pātai mō te pono mō te wā roa.

Ko te take matua kei roto i te ESR. Ko te ngaronga hiko P_loss = I_rms² × ESR. Ina piki te auau whakawhiti ki te 100kHz, ka heke tere te tauhohenga capacitive (Xc), ā, ka noho te ESR hei wāhanga matua o te aukati. Hei tauira, he capacitor me te ESR o te 40mΩ e mau ana i te iahiko ripple 2A, ko tōna ngaronga pūtau-kotahi he teitei ki te 0.16W. I roto i te wāhi kiato, he tino uaua ki te whakawātea i tēnei wera.Te otinga a YMINka whakaiti i te ESR ki te 20mΩ, ka whakaheke i te ngaronga ki te 0.08W i raro i ngā tikanga ōrite, ka haurua tika te whakaputa wera, ā, ka whakaoti rapanga i te pikinga pāmahana.

- Ngā Painga o te Otinga me te Tukanga a YMIN: Te Auahatanga Takirua i roto i ngā Rauemi me te Hanganga -

Ehara i te mea tūpono te iti o te ESR o YMIN, engari he hua nō te hangarau pūnaha:

Auahatanga Irahiko: Mā te whakamahi i tētahi pūhui kawe-teitei kua patenttia, ka piki ake te kawe-ionic mā te neke atu i te 30%, ka whakarite kia tino iti te aukati hekenga irahiko i ngā auau teitei.

Arotautanga o te Pepa Anode: Mā te whakairo hikohiko, ka hangaia he hanganga pūwero rite ki te kauhanga, ka whakanui ake i te horahanga mata whai hua me te whakapai ake i te putanga utu inamata.

Hanganga ātete ā-roto iti: Mā te hoahoa ātete-iti puta noa i te tukanga katoa, mai i te pouaka konumohe me te mono rapa ki ngā taura, ka whakaitihia te ātete pirinoa me te hiko hiko koretake.

- Te whakaū me te pono o ngā raraunga: Tukua ngā raraunga kia kōrero mōna ake -

I whakaritea e mātou ngā raraunga whakamātautau o ngā pūnga totoka YMIN VPX 25V 100μF i mua atu, ā, i muri mai i te whakapiringa anō. I whakahaeretia te tere huringa ESR whānui i roto i tētahi awhe. Ko te pikinga o tōna uara ESR he 15.1% noa iho. E whakaatu ana tēnei i te pumau wera pai o te hua me te pono o te tukanga, e whakarite ana i te mahi hiko pumau ahakoa i muri i te huihuinga SMT.

Ngā tauira tono o te ao tūturu

Hei tauira, ka whakamahia e te rihi tere Baseus 65W GaN teRaupapa YMIN VPX,ko tōna kaha ki te marara wera me te putanga pumau e tino whakaatu ana i ēnei tawhā mahi i roto i te hua whakamutunga.

Whakamutunga

Mō ngā kaihangarau e whai ana i te mahi tino pai, ko te uara ESR o tētahi pūnga kotahi te mea nui hei whakatau i te mahi whānui o te pūnaha. E mārama ana a YMIN Electronics ki tēnei, me tōna tūnga o "Mō ngā tono pūnga, tahuri kiYMIN mō ngā otinga"E hangai ana a YMIN ki tōna kaha ki te whakaoti rapanga hangarau uaua. Mā te whakarato i ngā hua taumata-teitei me ngā ESR iti iho i te 20mΩ, kei te tutuki tonu a YMIN i tana whāinga hua o te "whakakapi i ngā kaiwhakataetae o te ao me te noho hei waitohu matua," me te whakarato i ngā kaihoahoa tuku hiko ā-rohe ki ngā otinga wāhanga maramara pai ake, pono ake hoki i hangaia i te rohe.
