I ngā tau tata nei, kua tino rongonui ngā rihi GaN (Gallium Nitride) i roto i te ao hangarau. E mōhiotia ana mō tōna whai huatanga, tōna rahi kiato, me tōna kaha, e kiia ana ko ngā rihi GaN te heke mai o te hangarau utu. Engari ka taea e koe te whakamahi i tētahi rihi GaN hei utu i tō waea? Ko te whakautu poto he āe, ā, i roto i tēnei tuhinga, ka tūhuratia e mātou he aha ngā rihi GaN kāore i te hototahi noa ki ngā waea atamai engari he maha hoki ngā painga e tukuna ana e rātou ki ngā rihi tuku iho.
He aha te utunga GaN?
I mua i te ruku ki ngā āhuatanga motuhake o te utu i tō waea, he mea nui kia mārama koe he aha te utunga GaN. Ko te GaN he whakarāpopototanga mō te Gallium Nitride, he rauemi semiconductor kua whakamahia i roto i ngā momo hikohiko mō ngā tekau tau. Heoi, nō ngā tau tata nei ka whakamahia te GaN mō ngā utunga kaihoko. Ki te whakatauritea ki ngā utunga silicon tuku iho, he pai ake te mahi a ngā utunga GaN, he iti ake te wera e whakaputaina ana, ā, ka taea te whakaiti ake me te kore e whakaiti i te putanga hiko.
Hototahi ki ngā Waea
Ko tētahi o ngā pātai e pā ana ki ngā rihi GaN ko te hototahi ki ngā waea atamai. Ko te whakautu he āe tino kaha. Kua hangaia ngā rihi GaN kia mahi tahi me te whānuitanga o ngā taputapu, tae atu ki ngā waea atamai, ngā papa, ngā pona, tae atu ki ngā papatohu petipeti. He maha ngā tauranga o te nuinga o ngā rihi GaN, pērā i te USB-C me te USB-A, ā, he maha ngā whakamahinga hei utu i te nuinga o ngā taputapu.
Ko ngā waea atamai hou, inā koa ko ngā mea nō ngā waitohu pēnei i a Apple, Samsung, me Google, e tautoko ana i ngā hangarau utu tere pēnei i te USB Power Delivery (PD) me te Qualcomm Quick Charge. He maha ngā wā ka whakauruhia ngā kawa utu tere ki ngā rihi GaN, kia taea ai te utu i tō waea i tōna tere tautokona. Hei tauira, ki te tautoko tō waea i te utu tere 30W, ka taea e te rihi GaN me te USB-PD te tuku i taua hiko me te whai hua me te haumaru.
Ngā Painga o te Whakamahi i tētahi Rīhi GaN mō tō Waea
1. Ngā Tere Utu Tere
E mōhiotia ana ngā rihi GaN mō tō rātou kaha ki te tuku putanga mana teitei i roto i te āhua iti. Ko te tikanga ka taea e rātou te tautoko i ngā hangarau utu tere pēnei i te USB-PD me te Utu Tere, e taea ai e tō waea te utu tere atu i te rihi paerewa. Hei tauira, ka taea e te rihi GaN te utu i tētahi waea atamai hou mai i te 0% ki te 50% i roto noa i te 20-30 meneti, i runga i te taputapu me ngā whakaritenga rihi.
2.Kiko me te Kawe
Ko tētahi o ngā āhuatanga tino hira o ngā rihi GaN ko tōna rahi. Ko ngā rihi tuku iho e tuku ana i ngā putanga mana teitei he nui, he taumaha hoki. He rerekē, he iti ake, he māmā ake hoki ngā rihi GaN, he mea pai mō te haereere, mō te whakamahi rānei i ia rā. Ka taea e koe te whakauru ngāwari i tētahi rihi GaN ki roto i tō pēke, i tō pute rānei, me te kore e nui ake te taumaha, te rahi rānei.
3. Te Whai Hua o te Pūngao
He pai ake te penapena pūngao o ngā rihi GaN i ō rātou hoa silicon. He iti ake te whakapaunga pūngao hei wera, ā, ehara i te mea he pai ake mō te taiao engari he haumaru ake hoki te whakamahi. Ko te tikanga hoki o tēnei whai huatanga, he iti ake te tūponotanga o te wera rawa o ngā rihi GaN, ahakoa te utu i ngā taputapu maha i te wā kotahi.
4. Te Whakautu Maha-Pūrere
He maha ngā tauranga o ngā rihi GaN, ā, ka taea e koe te utu i tō waea, papahiko, me te pona i te wā kotahi. He tino whai hua tēnei mō te hunga e kawe ana i ngā taputapu maha, ā, e hiahia ana ki te whakaiti i te maha o ngā rihi e hiahiatia ana e rātou. Hei tauira, ka taea e te rihi GaN 65W me ngā tauranga USB-C e rua me te tauranga USB-A kotahi te utu i tō waea, papahiko, me te pona i te wā kotahi, me te kore e whakararu i te tere utu.
5. Hangarau Ārai-Āmua
I te mea he nui ake ngā taputapu e whakamahi ana i te USB-C me ngā hangarau utu tere, kei te piki haere te tūponotanga o ngā rihi GaN mō ngā rā kei te heke mai. Mā te haumi ki tētahi rihi GaN ināianei ka whiwhi koe i tētahi otinga utu maha-whakamahinga me te kaha e taea ai te whakahaere i ō taputapu o nāianei me ngā taputapu o muri mai.
He Āhuatanga Kino Kei Tērā?
Ahakoa he maha ngā painga o ngā rihi GaN, he iti noa ngā mea hei whakaaroaro māu. Tuatahi, he nui ake te utu o ngā rihi GaN i ngā rihi tuku iho. Heoi, he maha ngā wā ka tika te rerekētanga o te utu nā te pai o te mahi, te whai huatanga, me te roa o te ora.
Tuarua, kāore i te ōrite te hanganga o ngā rihi GaN katoa. He mea nui kia whiriwhiria he waitohu rongonui, kia mōhio hoki kei te tautoko te rihi i ngā tikanga utu tere e hiahiatia ana e tō waea. Tērā pea kāore e tutuki i ngā rihi GaN utu iti, kāore rānei i te pai te hanga te mahi i whakaaria mai, ā, ka kino pea tō pūrere.
Whakamutunga
Hei whakamutunga, ehara i te mea ka taea e koe te utu i tō waea mā te whakamahi i tētahi rihi GaN anake, engari he maha ngā painga o tēnei mahi. Mai i ngā tere utu tere me ngā hoahoa kiato ki te whai huatanga o te pūngao me te hototahi ki ngā taputapu maha, he haumitanga mohio ngā rihi GaN mō te hunga e hiahia ana ki te whakapai ake i tā rātou tatūnga utu. Ahakoa he nui ake te utu i te tīmatanga, ko ō rātou painga mō te wā roa ka pai te utu. I te whanaketanga tonu o te hangarau, kua rite ngā rihi GaN hei paerewa mō te whakakaha i ā tātou taputapu, e whakaatu ana i te tirohanga ki te heke mai o te hangarau utu. Nō reira, ki te whakaaro koe ki tētahi rihi hou mō tō waea, he mea tika kia whakaarohia he rihi GaN.
