1. Te Whakamāramatanga me te Mātāpono o Ku
Ko ngā matua aukume o ngā whakawhiti hiko me ngā inductors he wāhi matapihi e wātea ana mō te takai, ā, ko te tauwehenga whakamahinga matapihi Ku e tautuhia ana ko te ōwehenga o te horahanga whai hua tuturu o te waea parahi (konumohe rānei) takai ki te horahanga katoa o te matapihi matua aukume. E whakaatuhia ana penei:
Ku=Ac/Aw， I roto i ēnei, ko Ac te horahanga whakawhiti katoa o te waea takai, ā, ko Aw te horahanga o te matapihi matua aukume. Ko te Ku te whakaata i te taumata whakamahinga o te wāhi matapihi matua aukume. Ko te teitei ake o te uara Ku, ko te nui ake o ngā waea takai ka taea te whakauru ki te wāhi matapihi kotahi, ka taea te kawe i ngā iahiko nui ake, me te whakapai ake i te kaha tukatuka mana o ngā wāhanga hikohiko.
Ka taea te mārama ake i te whanaungatanga i waenga i te horahanga matapihi me te takai mā te hoahoa e whai ake nei:
2. Tikanga tātai a Ku
Hei tatau i a Ku, me whakatau motuhake te horahanga whakawhiti-wāhanga Ac o te waea takai me te horahanga matapihi Aw o te matua aukume.
Whakatau: Ka taea te whiwhi i te horahanga matapihi matua aukume Aw mā te ine i te roa me te whānui o te matapihi matua aukume, kātahi ka whakareatia ngā mea e rua. Mō ngā tauira matua aukume paerewa, ka taea hoki te tiki tika i te horahanga matapihi mai i te pukapuka raraunga i whakaratohia e te kaihanga matua aukume.
Tātaitanga: Tuatahi, me whakamārama te maha o ngā hurihanga N o te takai me te horahanga whakawhiti-wāhanga a o tētahi waea kotahi. Ka taea te tatau i te horahanga whakawhiti-wāhanga a o tētahi waea kotahi mā te whakamahi i te tātai horahanga porowhita a=π d2/4 i runga i te diameter waea d. Nō reira, ko te horahanga whakawhiti-wāhanga katoa o te waea takai ko Ac=N * a. Hei tauira, mēnā ka whakamahia e tētahi whakawhiti hiko he matapihi matua aukume he 50mm te roa me te 30mm te whānui, ko Aw=50 * 30=1500mm2, ko ngā hurihanga takai he 100, ā, ka tīpakohia he waea he diameter 0.5mm. Ko te horahanga whakawhiti-wāhanga o tētahi waea kotahi ko a=π * 0.52 ≈ 0.196mm2, Ac=100 * 0.196=19.6mm2, me Ku=19.6/1500 ≈ 0.013
3. Ngā āhuatanga matua e pā ana ki a Ku
a. Hanganga takai
He pānga nui tō te tikanga takai ki a Ku. Mā te tikanga takai maha-paparanga, ātaahua, ka taea te whakamahi pai ake i te wāhi matapihi ki te whakataurite ki te tikanga takai korekore me te matapōkere, ā, ka pai ake te uara Ku. Hei tauira, mā te whakamahi i te tikanga takai hanawiti (mā te wehewehe i te takai tuatahi kia rua ngā wāhanga me te whakapiri i te takai tuarua ki waenganui) kāore e taea te whakapai ake i te tohatoha o te papa aukume, engari ka whakapai ake hoki i te whakamahinga o te wāhi matapihi ki tētahi taumata.
b. Rauemi ārai
Hei whakarite i te mahi ārai hiko o te takai, me whakamahi ngā rauemi ārai pēnei i te peita ārai me te rīpene ārai. Heoi, ka nohoia e ēnei rauemi ārai tētahi wāhi matapihi. Ka matotoru ake te rauemi ārai, ka iti ake te wāhi e toe ana mō te waea, ā, ka heke iho te uara Ku. Nō reira, ko te whiriwhiri i ngā rauemi ārai angiangi me te mahi teitei, me te whakatutuki i ngā whakaritenga ārai he huarahi whai hua hei whakapai ake i te Ku.
c. Āhua matua aukume
He rerekē ngā āhua me ngā rahi o ngā matapihi o ngā matua aukume, ā, ka pā pea tēnei ki ngā uara Ku. Hei tauira, ki te whakaritea ki ngā matua aukume toroidal, he maha ake ngā matapihi o ngā matua aukume momo-E, ā, he māmā ake te takai i ngā takai, ā, tera pea ka eke ki ngā uara Ku teitei ake; Ahakoa he pai ngā matua aukume āhua porowhita i roto i te parenga aukume me ētahi atu āhuatanga, he uaua te takai, ā, he tino uaua te whakamahi i te wāhi matapihi. He nui ake ngā wero e pā ana ki te whakapai ake i te uara Ku.
4. Te hiranga o Ku i roto i te hoahoa mahi
a. Whakarei ake i te mātotoru o te mana
I roto i te ia o te whakaiti me te whakaiti i te māmā o ngā taputapu hiko mana hou, kua noho te whakapai ake i te kiato mana hei whāinga matua. Mā te arotau i te Ku, ka taea te whakanui ake i te horahanga whakawhiti o ngā waea takai i roto i te wāhi matapihi matua aukume iti, ka taea ai te rere o ngā iahiko nui ake, me te whakapai ake i te kaha tukatuka mana o ngā whakawhiti me ngā inductors. Mā tēnei ara, me te rōrahi ōrite, ka taea e te taputapu te whakatutuki i te putanga mana teitei ake hei whakatutuki i te hiahia hiko e piki haere ana.
b. Whakaitihia ngā utu
Mā te whakanui ake i te Ku e tika ana, ka taea te whakatutuki i te tuku mana kotahi me te kore e whakanui ake i te rahi o te matua aukume. Ka whakaitihia te hiahia mō ngā matua aukume rahi ake, ā, ka whakaitihia te utu o ngā matua aukume. I taua wā, mā te whakamahi pai i ngā matapihi ka whakaitihia te moumou o ngā rauemi takai, ka penapenahia ngā utu. Nō reira, ko te arotau i te Ku he huarahi nui hei whakataurite i te mahi me te utu.
c. Whakapai ake i te mahi whakamarara wera
Ina iti te Ku, ka horapa noa te takai i roto i te matapihi, ka hua ake pea he tohatoha kore taurite o te papa aukume me te kukū wera ā-rohe. Mā te arotau i te Ku me te whakakī i te wāhi matapihi i roto i te takai ka āwhina i te whakapai ake i te tohatoha o te papa aukume, te whakaiti i te ātete AC o te takai, te whakaiti i ngā ngaronga takai, ā, ka whakarei ake i te mahi whakamarara wera me te whakarite kia pumau te mahi a te taputapu.
5. Ngā Tikanga me ngā Mahi mō te Whakapai Ake i te Ku
a. Te whakamahi i te hangarau takai matatau
Mā te whakamahi i ngā taputapu matatau pēnei i ngā mīhini takai aunoa, ka taea te whakatutuki i te takai tika ake, kiato ake hoki, ka karohia ngā raruraru o te wetewete me te kore taurite ka puta i te wā e takai ā-ringa ana, ā, ka pai ake te whakamahinga o te wāhi matapihi. I taua wā anō, ka taea hoki e ētahi tukanga takai motuhake, pēnei i te takai wāhanga me te takai taurite, te arotau i te tahora takai me te whakapai ake i te Ku kia rite ki ngā whakaritenga hoahoa motuhake.
b. Kōwhiria ngā waea me ngā rauemi whakamahana e tika ana
Mā te whakamahi i ngā waea kawe hiko teitei, ka taea te whakamahi i ngā waea angiangi i raro i te kaha kawe iahiko kotahi hei whakarite i ngā hurihanga maha atu o ngā takai i roto i te matapihi, me te whakanui ake i te Ac. I taua wā anō, ka tīpakohia ngā rauemi whakamarumaru angiangi hou pērā i ngā kiriata whakamarumaru nano hei whakarite i te mahi whakamarumaru me te whakaiti i te wāhi e nohoia ana e ngā rauemi whakamarumaru me te whakapai ake i te Ku.
c. Te hoahoa arotau o te matua aukume
Kōwhiria ngā matua aukume o te āhua me te rahi e tika ana i runga i ngā āhuatanga tono motuhake me ngā whakaritenga mahi. Mō ētahi hoahoa he nui ngā whakaritenga Ku, ka taea te whakaaro ki ngā matua aukume ritenga kore-paerewa hei arotau i te āhua me te rahi o te matapihi matua aukume kia tutuki ai te pānga whakamahinga matapihi pai rawa atu.
Ka rere te tauwehenga whakamahi matapihi Ku puta noa i te tukanga katoa o te hoahoa o ngā whakawhiti hiko me ngā inductors, ā, ka pā nui ki te mahi, te utu, me te pono o ngā wāhanga hikohiko. Mā te mārama hohonu ki te kaupapa o Ku, te tatau tika i ōna uara, te tātari whānui i ngā āhuatanga awe, me te whakamahi i ngā tikanga arotau whaitake, ka taea te hoahoa i ngā whakawhiti hiko me ngā inductors me te mahi pai ake me te utu iti iho, ka whakatairanga i te whanaketanga tonu o te hangarau hikohiko mana.
