Āhuatanga Power-Supply

āhuatanga mana supply-

He maha ngā āhuatanga mana supply-e pā ratou mahi:

'Auhia:  Ko te rerekētanga i roto i te dc putanga ngaohiko rite te mahi o te wā i te ngaohiko tamau aho, kawenga, me ambient pāmahana.

Whakautu hihiri:  kia mahi te supply te mana i roto i te pūnaha i reira i reira he he whakaritenga ki te whakarato whakautu hihiri nohopuku ki te huringa i roto i te mana kawenga. E taea e te take mo te kawenga o microprocessors nui-tere ki ngā mahi whakahaere-mana. I roto i tenei take, kia waiho te microprocessor i roto i te āhua tūtatari me runga whakahau me tīmata ake tahuri atu tonu, e whakanoho ngā hihiri tiketike ki auau rōnaki nohopuku i runga i te supply mana ranei. Hei hāngai te microprocessor, me rōnaki ngaohiko whakaputa o te supply ake ranei ki raro, i roto i te wā wa i whakaritea, engari kahore overshoot nui. 

Te kaha:  Ratio o putanga-ki-tāuru mana (i roto i te ōrau), whanganga i te nāianei kawenga hoatu ki ngā āhuatanga raina iti (Pout / Pin).

Wā Holdup:  Time i roto i nei tonu ngaohiko whakaputa he supply o te mana i roto i whakatakotoranga e whai ake nei i te mate o te mana tāuru.

Inrush nāianei:  nāianei tāuru Peak inamata unu e te supply mana i tahuri-i runga i.

Paerewa International:  Tauwhāiti whakaritenga haumaru te supply o te mana, me te tīkina EMI (pokanoa hiko) taumata. 

Wehe:  wehenga Electrical i waenganui i te wāhi me te putanga o te supply mana whanganga i roto i volts. He kore-taratahi he huarahi dc i waenganui i te wāhi me te putanga o te supply, te mea kaimahi he supply mana taratahi te hiko ki te whakakore i te huarahi dc i waenganui i kōkuhu me te whakaputa.

Ture Raina:  Huria i roto i te uara o dc putanga ngaohiko hua i te huringa i roto i te ngaohiko ac tāuru, tohua rite te huringa i roto i ± mV ranei ±%.

Utaina ture:  Huria i roto i te uara o dc putanga ngaohiko hua i te huringa i roto i te kawenga i tuwhera-iahiko ki te nāianei putanga mōrahi-tauanga, tohua rite te huringa i roto i ± mV ranei ±%.

Putanga haruru:  Ka taea e puta tenei i roto i te supply mana i roto i te puka o popoto o te pūngao auau tiketike. Meinga ana te haruru e tohutohutia me fakahoko o capacitances Parasitic i roto i te supply mana i roto i tona huringa whakahaere. Ko tōna kaha tīwera tāupe a taea whakawhirinaki i runga i te parenga ia utanga, te tātari waho, a he pehea te reira inenga. 

Putanga ngaohiko kuti:  Most power supplies have the ability to “trim” the output voltage, whose adjustment range does not need to be large, usually about ±10%. One common usage is to compensate for the dc distribution voltage drop within the system. Trimming can either be upward or downward from the nominal setting using an external resistor or potentiometer.

ine Periodic me tupurangi (PARD): Hiahiatia wā (pōkare) ranei aperiodic (haruru) ine o te putanga ngaohiko mana supply-i tona uara mata. Ua faaite PARD te i roto i mV tihi-ki-tihi rms ranei, i te hōkaiipurangi whakaritea.

Tihi o nāianei:  Ko te nāianei mōrahi e taea te supply mana whakarato mō te wā poto. 

Mana Peak:  te tino mana putanga mōrahi e taea te supply mana hua kahore kino. Ko te nuinga te reira i pai tua atu i te āheinga putanga mana pono tonu, me te kia anake ka whakamahia pinepine.

Power supply-whakaraupapa:  Raupapa tahuri-i runga i me atu o kai mana kia hiahiatia i roto i ngā pūnaha ki te ngaohiko whakahaere maha. Ko, Me tono ngaohiko i roto i te raupapa motuhake, te kore e taea te pakaru te pūnaha. Hei tauira, i muri i te tono i te ngaohiko tuatahi, me te tae te reira i te uara motuhake, e taea te ramped ake he ngaohiko tuarua, a na i runga i. Mahi whakaraupapa i roto i te whakamuri, ka nekehia atu te mana te, ahakoa kahore he te tikanga tere rite te nui o te raruraru rite tahuri-i runga i.

Mamao i runga i / atu:  meinga tenei te i runga i whakakā ki te tahuri kai mana i runga i a atu. Power supply-ngā raraunga-rau te tikanga taipitopito te tawhā dc mō mamao i runga i / atu, rārangi i te i runga i me atu ngā taumata arorau hiahiatia.

Tikanga Mamao:  aroturuki te supply mana angamaheni tona ngaohiko putanga, me te whāngai i te wahi o reira whakahokia ki te supply ki te whakarato ngaohiko ture. I roto i tenei ara, ki te whangai ana te putanga ki te whakatika hinga ranei, regulates te urupare ngaohiko whakaputa o te supply. Heoi, ki te mau tonu i te putanga tonu i te pikaunga, te supply te mana kia mau aroturuki i te ngaohiko i te kawenga. Ko, hononga i putanga he supply o te mana ki tona kawenga i resistance me te nāianei e rerengia ana i roto i te hunga e hua i te maturuturunga iho ngaohiko e hangaia e te rerekētanga ngaohiko i waenganui i putanga o te supply me te kawenga tūturu. Hoki te ture tino pai, kia waiho te ngaohiko whangai hoki ki te supply mana te ngaohiko kawenga tūturu. E rua (me me tango) hononga tikanga mamao o te supply aroturuki te ngaohiko kawenga tūturu, he tino iti te wahi o nei te ka whangai hoki ki te supply ki te maturuturunga iho ngaohiko iti rawa no te mea te nāianei i roto i te hononga tikanga mamao e rua. Ka rite ki te putanga, whakaritea te ngaohiko tono ki te kawenga kei te.

Pōkare:  whakatika i a tātari hua putanga he supply o whakawhitinga mana i roto i te wāhanga ac (pōkare) e eke i runga i tona putanga dc. Auau Ripo ko etahi maha wāhi o te auautanga whakawhitinga o te pūtahuri, e tei runga i te āhuawhatunga pūtahuri. Ko ngā watea i kawenga o nāianei pōkare, engari e taea te heke i te tātari pūnga waho.

Aroturuki:  A, no te whakamahi i maha kai mana putanga kotahi, neke atu rānei ngä whai ai tetahi ki huringa i roto i te aho, kawenga, me te pāmahana, kia pupuritia e ia i te taua ngaohiko whakaputa hautanga, i roto i kātakí aroturuki i tohua, ki te whakapai kanohi ki te uara noa.
