He maha ngā momo pūnga iahiko. E rua ngā momo pūnga iahiko matua, arā, ko te pūnga iahiko pumau me te pūnga iahiko taurangi. Ka whakarōpūtia ēnei i runga i tō rātou kaha, arā, ko te pūnga iahiko porotaka me te pūnga iahiko kore-porotaka. Ko ngā pito pai me ngā pito kino kua tohua ki runga i ngā pūnga iahiko. Ka taea te hono i ngā pūnga iahiko porotaka i roto i ngā ara iahiko i roto i te kotahi ara motuhake, engari ko ngā pūnga iahiko kore-porotaka ka taea te hono i tetahi atu ara o ngā ara iahiko. He rerekē ngā āhuatanga me ngā whakaritenga o ngā pūnga iahiko i roto i te hiko. I runga i ō rātou āhuatanga me ngā whakaritenga, ka taea te whakamahi i roto i ngā tono rerekē.
Ngā momo pūnga
1. Ngā pūnga hiko
He pūnga iahiko porowhita ēnei. He mea hanga te anode, te pito pai rānei, ki te konganuku, ā, mā te anodization ka hangaia te paparanga waikura. Nō reira, ka mahi tēnei paparanga hei ārai. E toru ngā momo pūnga iahiko hiko e whakamahia ana mō ngā momo rauemi rerekē. Ā, ka taea ēnei te whakarōpū penei:
Ngā pūnga hiko konumohe
Ngā pūnga hiko tantalum
Ngā pūnga hiko niobium
A. Ngā pūnga hiko konumohe
I roto i tēnei momo pūnga iahiko, he konumohe te mea hanga ai te anode, te pito pai rānei, ā, ka mahi tēnei hei dielectric. He iti ake te utu o ēnei pūnga iahiko i ērā atu momo pūnga iahiko. He tino nui te manawanui.
B. Ngā pūnga hikohiko Tantalum
I roto i ēnei pūnga hiko, ka whakamahia te konganuku hei hikohiko. Kei te wātea ēnei momo i roto i te momo mata me te āhua maramara mō te whakamau mata, ā, he kaha (10 nf ki te 100 mf) ō rātou pūnga hiko. He nui te pai o te rōrahi. He iti te manawanui. He tino pumau, he pono hoki.
C. Ngā pūnga hiko niobium
Kāore ēnei i te tino rongonui pērā i ngā pūnga hiko konumohe me te pūnga hiko tantalum. He iti rawa te utu, he iti ake rānei te utu.
2. Ngā pūnga hiko uku
Kāore ēnei i te tino rongonui pērā i ngā pūnga hiko konumohe me te pūnga hiko tantalum. He iti rawa te utu, he iti ake rānei te utu.
•Akomanga I-Te pumau teitei me ngā mate iti
1. tino tika, ā, he pumau te kaha
2. tino pai te pumau o te wera
3. iti te manawanui (1 0.5%)
4. te iti o te rerenga o te iahiko
5. Ātete me ngā oscillator
•Akomanga II-iti ake te tika me te pumau e rite ana ki ngā pūngahiko akomanga-I
1. he tino pai te whai huatanga o te rōrahi, ā, he rite ki ngā pūnga iahiko akomanga-I.
2. ngā huringa me te ngaohiko whakahāngai
3. Ngā pūnga kiriata
♦ I roto i tēnei kiriata pūnga hiko, ka whakamahia te kiriata kirihou hei rauemi dielectric. He momo rerekē pērā i te polyester polypropylene me te polystyrene. He tino pumau, he pai hoki te pono, ko tōna whakatauranga ngaohiko he IOU ki te 10 KV, ā, e wātea ana ēnei i roto i te whānuitanga o te PF me te MF.
4. Pūngao nui
♦ E mōhiotia ana hoki ko te ultra capacitor, he nui te utu e rongoa ana e rātou. Ka rerekē te whānuitanga o te capacitance mai i te torutoru farad ki te 100 farad, ko te whakatauranga ngaohiko kei waenga i te 2.5 ki te 2.9.
5. Pūnga hiko mika
♦ He tika ēnei, ā, he pai te pumau o te pāmahana. E whakamahia ana i roto i ngā tono RF me ngā tono ngaohiko teitei. He utu nui, koia ēnei ka whakakapia e ētahi atu pūnga hiko.
6. Pūngahiko taurangi
♦ E mōhiotia ana hoki ko te pūnga whakapūmau, e whakamahia ana mō te whakatikatika i ngā taputapu, mō te hanga, mō te ratonga rānei. Ka taea te whakarerekē i te whānuitanga kua whakaritea. E rua ngā momo pūnga whakapūmau.
♦ Pūnga whakapūmau uku me te hau.
♦ Ko te pūnga iti rawa kei te 0.5 PF, engari ka taea te whakarerekē ki te 100PF.
Kei te wātea ēnei pūnga hiko mō te whakatauranga ngaohiko tae atu ki te 300v, ka whakamahia ēnei pūnga hiko i roto i ngā oscillator tono RF me ngā ara iahiko whakahāngai.
