Ngōhiko rectifier - te whakaahuatanga o te tawhā, me ngā āhuatanga o

ngōhiko rectifier - he pūrere hiko mō te tahuri i te nāianei tamau ki te nāianei tauutuutu. Ko te pūrere e rua-kawehiko, e kua anake kotahi-ara (unipolar) kawe ia hiko tenei. Rectifier ngōhiko o rauemi Semiconductor me pera-ka karanga piriti ngōhiko (ina e hono wha p hauroki i roto i takirua i roto i te take kotahi) whakakapi ignitron me mārua ngōhiko.

Ko te pānga o te whakatikatikaina o tauutuutu nāianei, me te tahuri te reira ki te whakawhitinga tūturu puta i te Semiconductor-whakarewa, maitai-Semiconductor te whakawhitinga irahiko-rua pera-ka karanga i roto i te tahi mau tioata (hei tauira, silicon, germanium, selenium, parahi waikura) ranei. maha taua tioata te hanga i te pūtake o te pūrere.

ngōhiko Semiconductor rectifier whakamahia i roto i te hikohiko, hiko me ngā pūrere hiko. I roto i te meka, te hangatonu - tenei tauiraa tauutuutu nāianei (ngaohiko) ki te nāianei o tetahi wehenga tawhiti (pumanawa DC). Me tenei momo o whakatikatikaina i roto i te toi mō te whakatuwhera me te kati iahiko hiko, whakawhiti me te rapunga o tohu hiko me ngātere, a mo te maha atu panoni ōrite. e kore e āhuatanga ngōhiko pērā pērā i te mahi, tawhā pūmautanga, te kaha o Junctions PN takoto ki tapaea ki a ia i tetahi whakaritenga motuhake.

kua he tetahi tawhā hiko me ngā āhuatanga o te te p he pūrere taua:

- i mea ngaohiko whakamua uara o nāianei (tangohia te uara toharite) ;

- whakataka nāianei i te uara i homai o te ngaohiko whakamuri, me te pāmahana (uara toharite) ;

- te uara tīwera mo te mōrahi whakamuri whakaaetia ngaohiko;

- te uara toharite o te nāianei whakamua;

- ngā uara auau kahore aratau whakaiti;

- resistance.

Kei te maha haapotohia huaina noa rectifier ngōhiko te rectifier. Ka rite ki te wāhanga o te mania, te mea ātete tiketike ki te nāianei e rere i roto i te kotahi aronga me te iti ki taua i puta i roto i te aronga whakamuri. ai tenei he whakatikatika nāianei.

I roto i te pūrere pērā i te rectifier ngōhiko, he ka makona ratou iti ngā auau. auau Whakahaere mō whakamahi ahumahi he pūrere taua ki te AC ki DC faafariuraa ko 50 Hz. whakaaro Whakatepe auau te ki kia kaua e neke atu i te 20 kHz.

Ka taea te wehea ngōhiko rectifier rite te pūrere hiko ki te maha ngā rōpū rite ki te uara toharite o te nāianei hāngai mōrahi. Tenei ngōhiko iti mana (0.3 Amps), te mana reo (i 0.3 te ki 10 A) me te ohipa taimaha (mana) te p rectifier (neke atu i te kotahi tekau amperes).

Me ngā te tawhā matua o taua whakaaro hiko pērā i te ngōhiko rectifier, me te whānuitanga whakahaere mo te pāmahana ambient (te tikanga pae reira i -50 ki te +130 degrees mo te momo tino noa ngōhiko - silicon) me te pāmahana tinana mōrahi (he momo o ngā tawhā, i runga i te kaha o te whakarite me te kaiwhakanao rānei).
