Hoahoa Utu Ahokore me te Utu Wātahi
Nā te horapa haere o ngā taputapu atamai i roto i te tekau tau kua pahure ake nei, kua uaua haere ngā hiahia utu. He maha ngā taputapu kei roto i ā tātou tēpu i ēnei rā: he waea pūkoro, he taringa taringa, he mataarataki atamai, he pēke hiko rānei. Koinei te wāhi e tika ai te ariā o tētahi rihi ahokore me te utunga i te wā kotahi—he otinga e taea ai te utu i ngā taputapu maha i te wā kotahi me te kore he taura e raruraru ana. Heoi, ko te hoahoa i tētahi rihi ahokore maha-taputapu he nui atu i te whakanui noa i te rahi o te papa utu. He wero hangarau anō hoki pērā i te whakahaere hiko, te pokanoa hikohiko, te whakatakotoranga koiri, te whai huatanga, tae atu ki ngā āhuatanga haumaru me te wheako kaiwhakamahi. Ka matapakihia e tēnei tuhinga te huarahi hoahoa, ngā wāhanga nui, me ngā whakaaro mahi mō te whakawhanake i tētahi rihi ahokore ka taea te utu i te wā kotahi.
1. Ariā Taketake o te Rīhi Ahokore
Ko te tikanga, ko te mahi a ngā rihi ahokore i runga i te kaupapa o te whakapūngao hikohiko. Kei roto i te rihi he koiri tuku e whakaputa ana i tētahi papa aukume tauutuutu. Ka puta he iahiko i roto i te koiri kaiwhiwhi i roto i te taputapu i tēnei papa, ka hurihia hei hiko DC hei utu i te pākahiko. Ko te paerewa tino noa ko te Qi (Wireless Power Consortium), e whakahaere ana i te whakawhitiwhiti kōrero, te haumarutanga, me te hototahi i waenga i ngā kaihanga.
I roto i te utunga i te wā kotahi, ka whakawhānuihia tēnei ariā taketake ki ngā huarahi e rua:
1. Maha-kōiri (he maha ngā kōiri i roto i te papa kotahi): ka taea te whakanoho i te taputapu ki ētahi wāhi; he kōiri motuhake tō ia wāhi.
2. Tuku maha-hongere, maha-awa rānei: he ara iahiko taraiwa motuhake tō ia koiri/kawenga kia taea ai te whakahohe me te whakahaere i te wā kotahi.
Ka taea e ngā mea e rua te utu i te wā kotahi, engari he rerekē te uauatanga o te hoahoa me te utu.
2. Ngā Whakaritenga Pūnaha: He aha tāu e hiahia ana kia tutuki?
I mua i te urunga atu ki ngā taipitopito hangarau, tautuhia ngā āhuatanga o te hua:
– Te maha o ngā taputapu: 2, 3, neke atu rānei? Hei tauira, waea + pane taringa + mataaratanga atamai.
– Whāinga mana: 5 W, 10 W, 15 W (he mea noa i runga i te Qi), he huinga mana rerekē rānei mō ia rohe.
– Ngā rahinga o te hua: papa papatahi, tūnga, tauira "tauranga" taputapu-toru rānei.
– Pūtake hiko tāuru: USB-C PD (hei tauira, 9V/2A, 12V/2A, 20V), urutau motuhake, pūwero DC rānei.
– Hototahi: Paerewa Qi, Qi2 (me te whakaritenga aukume), tautoko taputapu motuhake rānei.
Mā ēnei whakaritenga e tautuhi te āhuahanga mana, te whakapaunga katoa, me te rautaki whakamatao.
3. Hanganga Mana mō te Utu Wā Kotahi
Me whakahaere pūmau te mana ina utua ngātahi. E rua ngā hoahoa rongonui:
a) Kotahi te pūtake hiko nui + te tiritiri maha-hongere
Ka heke te pūtake hiko e haere mai ana (hei tauira, he PD USB-C 20V) mā te kaitahuri DC-DC ki te ara hiko e hiahiatia ana e te koiri taraiwa. Kātahi ka wehea te hiko ki waenga i ngā hongere tuku maha, ka taea te whakahohe i te wā kotahi. Ko ngā painga ko te pai ake o te whai huatanga me te hoahoa urutau māmā ake. Ko te wero ko te hiahia kia āta whakahaeretia kia kore ai te tapeke o te hiko e neke ake i te kaha o te urutau, ā, kia kore ai e heke te hiko.
b) He waeine hiko motuhake tō ia rohe
He taraiwa motuhake tō ia koiri, ā, he āhua motuhake hoki te whakahaere mana. Mā tēnei ka māmā ake te wehewehe me te whakatikatika haruru, engari ka nui ake te utu o ngā wāhanga, te wāhi PCB, me te uaua o te wera.
I ngā huarahi e rua, ko te mana whakahaere ka mahia e tētahi pūmana iti, e tētahi IC whakahaere mana rānei e aroturuki ana i te iahiko, te ngaohiko, te pāmahana, me te tūnga o te pūrere.
4. Tatūnga Koiri: Te karo i ngā "Wāhi Matapo" me te Whakararuraru
Ko te hoahoa ā-tinana o te koiri te mea nui e whakatau ana i te whakamarie o te kaiwhakamahi. Ko te wero nui ko te tūnga o te taputapu. Ki te waiho te waea e te kaiwhakamahi kia paku kore e anga whakamua, ka heke te pai o te mahi, ka mutu pea te utu, ka piki ake rānei te wera.
Mō ngā hoahoa tukutahi, ko te tikanga ka whakaritea ngā koiri:
– E toru ngā rohe motuhake (hei tauira, maui-pokapū-matau) mō ngā taputapu e toru.
– Taupokina ngā koiri hei whakawhānui i te wāhi hopu, engari ka nui ake te tūponotanga o te hononga i waenga i ngā koiri.
– Whakakotahitia ki te pepa ferrite hei tuku tika i te rerenga aukume ki te pūrere, hei whakaiti hoki i te turuturu o te mara ki raro (hei tiaki i te PCB me te whakanui ake i te pai o te mahi).
Ka puta te pokanoa ina mahi tahi ngā koiri e rua e tata ana, ā, ka taea e ō rāua papa aukume te awe tetahi ki tetahi. Ko ngā otinga ko:
– Kia tika te tawhiti i waenga i ngā koiri.
– Te tāpiritanga o te ferrite me te parepare.
– Ngā taraiwa koiri me te auau me te āhua e whakahaerehia ana e te kaiwhakahaere kia kore ai e pokanoa tetahi ki tetahi.
– Rautaki whakarea-wā (whakawhiti tere). Heoi, ehara tēnei i te mea kotahi noa iho; ka taea tonu te ahua kotahi ahakoa he tino tere te whakawhiti, engari ka taea te heke te mana whai hua mō ia taputapu.
5. Te Kimi Pūrere (Te Kimi i ngā Mea Tauhou me te Kimi Pūrere)
Ko te tikanga, ka kitea te taputapu e ngā rihi: te tirotiro mēnā he taputapu e whakahohea ana e te Qi. Ki te kore he taputapu, kaua te tuku hiko e tino hohe hei karo i te moumou hiko me te mōrearea o te wera i ngā mea ke.
Ngā wāhanga haumaru nui:
– FOD (Kitenga Mea Tawahi): kitea ai ngā konganuku tawahi (ngā moni, ngā kī) ka wera ake nā te whakapūngao.
– Parenga wera: pūoko pāmahana (NTC/thermistor) i roto i te rohe koiri me te IC taraiwa.
– Te parenga o te au nui/te ngaohiko nui i runga i te tāuru me ia hongere.
I roto i ngā hoahoa tukutahi, me whakahaere ngā FOD mō ia rohe. Ko tētahi hapa noa ko te "tinihanga" o ngā FOD e ngā taputapu i ētahi atu rohe, e hiahiatia ana he rauropi whakatikatika me te kimi matatau ake.
6. Te Whakawhitiwhiti Kōrero me te Whakahaere: Te Whakahaere i te Mana o Ia Pūrere
Ko te paerewa Qi e uru ana ki te whakawhitiwhiti kōrero i waenga i te tuku me te kaiwhiwhi hei whakatau i te taumata hiko e hiahiatia ana. Ina maha ngā taputapu e utu ana i te wā kotahi, me:
– Tohaina te hiko kia rite ki ngā hiahia o ia taputapu.
– Kaua e nui ake te mana katoa i te pūtake.
– Ka whakahaere i ngā āhuatanga hihiri: kua kī tetahi taputapu, kua whakatakotorangahia tētahi atu, kua nekehia rānei tetahi taputapu.
Hei tauira, ko te mana katoa o te urutau he 30 W. Mena e rua ngā waea e tono ana i te 15 W mō ia waea, ka taea e te pūnaha te whakarato i te 15 W mō ia waea. Heoi, mena e toru ngā taputapu, ā, ko te katoa o te tono he 40 W, me whakawhāiti te pūnaha i te mana: hei tauira, 15 W + 10 W + 5 W, me whakaiti rānei i te katoa ki te 10 W kia pumau ai.
7. Hoahoa Wera: Ngā Raru Tino Noa
Ka whakaputahia te wera e ngā rihi ahokore mai i:
– ngā ngaronga i roto i te koiri (ātete, ia hurihuri),
– ngā mate whakawhiti i roto i ngā taraiwa,
– ngā ngaronga i roto i te taputapu e whiwhi ana,
– te turuturu o te rerenga me ngā ngaronga FOD.
I te wā e utu tahi ana, ka piki ake tēnei wera. Nō reira:
– Whakamahia ngā rauemi anga hei āwhina i te whakamarara i te wera (hei tauira, te konumohe me te whakamarumaru haumaru, te kirihou rānei me te horapa wera).
– Tāpirihia ngā papa whakamahana me ngā vias whakamahana ki te PCB.
– Whakatakotoria te pūoko pāmahana ki te taha o te koiri me ngā wāhanga wera (MOSFET/taraiwa).
– Whakaarohia he pā hau iti mō ngā tauira kaha-nui (ahakoa ka nui ake te haruru me te utu).
Ko te whāinga o te hoahoa wera ehara i te mea kia "kore e wera", engari kia mau tonu te pāmahana ki roto i ngā rohe haumaru kia kore ai te taputapu e whakaroa, e mutu rānei te utu.
8. Atanga Kaiwhakamahi: Māmā engari he Whai Kōrero
Ka raru pea te utunga i te wā kotahi mēnā kāore ngā kaiwhakamahi e mōhio ko tēhea rohe e hohe ana. He otinga UX māmā:
– Ngā tohu LED mō ia rohe (hei tauira, mā: tūtatari, kikorangi: utu, kakariki: kī, whero: hapa/FOD).
– Tāngahia ngā tohu, ngā kakano rānei o te wāhi whakatakotoranga.
– Te whakarārangi aukume (i runga i te pūnaha Qi2) hei whakarite i te tūranga tika o te koiri me te whakapiki i te whai huatanga.
Ka taea e te UX pai te whakaiti i te amuamu "i ētahi wā ka utua, i ētahi wā kāore" e pā pinepine ana ki ngā rihi ahokore.
9. Tauira Ariā Hua: Rīhi 3-i-te-1
Ko tētahi āhuatanga noa ko te 3-i-te-1: waea + mātaaratanga atamai + pane taringa.
– Rohe pūkoro: 15 W Qi.
– Rohe taringa: 5W Qi.
– Rohe mataaratanga atamai: he maha ngā wā ka whakamahia he paerewa motuhake, he koiri iti rānei kua whakaritea.
– Tāurunga: USB-C PD 30–45 W mō te wāhi pane.
– Mana Whakahaere: 3 ngā hongere, kei ia hongere he pūoko pāmahana, he FOD, me te rohe mana.
Ko tēnei ariā e hiahia ana kia tino tika te hoahoa ā-ringa, inā koa mō ngā mataaratanga atamai e hiahia ana kia tino tika te tūnga.
10. Whakamātautau me te Tiwhikete
Kia oti te hoahoa, ko te taahiraa nui ko te whakamātautau:
– Whakamātautau hototahitanga me ngā taputapu maha (ngā matotoru o te pouaka, ngā kōwae kāmera e kokiri ana, me ētahi atu).
– Whakamātautau kawenga mōrahi i te wā kotahi mō te wā roa (whakamātautau mimiti wera).
– Whakamātautau FOD me ngā momo mea whakarewa.
– Whakamātautau EMC/EMI kia kore ai e pokanoa ki ētahi atu taputapu.
– Te tiwhikete Qi (mēnā kei te hiahia koe ki te whakamahi i te tohu Qi mana) me te hanganga ture mō te haumaru hiko (e whakawhirinaki ana ki te whenua).
Ehara te tiwhikete i te mea he tikanga noa iho—e huraina ana ngā take hoahoa pēnei i ngā wera nui, ngā hekenga o te whai huatanga, te pokanoa rānei i waenga i ngā koiri.
Te Katinga
Ko te hoahoa o tētahi rihi ahokore me te utunga ā-wā kotahi he huinga o te hangarau hiko, te hikohiko, te hangarau wera, te hangarau whakahaere, me te hoahoa hua. Ko te arotahi matua ko te whakarite kia taea te utu i ngā taputapu maha i runga i te pumau, te haumaru, te whai hua, me te ngāwari. Ko te kī ki te angitu kei roto i te whiriwhiri i te hoahoa hiko tika, he tahora koiri e whakaiti ana i te pokanoa, he rauropi whakahaere atamai mō te tiritiri hiko, me te hoahoa wera kua whakaarohia pai. Mā tēnei huarahi, ka taea e tētahi rihi ahokore maha-taputapu te noho hei otinga whai hua e tino whakarei ake ana i te whakamarie o te kaiwhakamahi, kaua ko te mea he taputapu tāpiri noa iho i runga i te tēpu.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga kia hangarau ake (me ngā hoahoa poraka, ngā rārangi wāhanga, me ngā āhua porowhita) kia rongonui ake rānei (kāhua maheni hangarau) kia rite ki tāu hunga whakarongo.
