Ko te taputapu me te whakahaere parau tumu o te rectifier taiawhio ngōhiko piriti

Tauutuutu nāianei hiko te tahuri ki a DC pākau i roto i te whakamahi o iahiko hiko motuhake - piriti ngōhiko. Kei te wehea ngōhiko piriti rectifier iahiko ki e rua putanga: kotahi-wāhanga, me te toru-wā.

I roto i te huānga rectifier matua ko te ngōhiko. Te hanganga, he mea he paraharaha o te maramara Semiconductor ki ngā rohe kawe ia rerekē e rua. He āhuatanga ko te irava unilateral o te nāianei hiko, i runga i te aronga o te rere rānei.

Hanganga me te mahi o te ngōhiko rectifier i runga i ngā āhuatanga o te Semiconductor PN whakawhiti i waenganui i te rohe. Tei Ko tōna ātete i runga i te wehenga tawhiti o te ngaohiko waho. I roto i te take kotahi, he nui, i roto i te tahi atu i te reira - paku.

Ko te piriti kotahi-wāhanga ngōhiko

A, no te te tāuru - AC ngaohiko ngaru sine i roto i ia hawhe huringa o te nāianei haere i roto i te rua o te p me te tahi atu katia. Ka rite ki te hua, i hanga te mania putanga o te pōkare ngaohiko ngōhiko piriti rectifier he auau rua nga wa nui atu i i te kokoru.

Ko te ara iahiko piriti e toru-wāhanga

Ka whakamahia e tēnei ara iahiko ngōhiko rectifiers hawhe-piriti. whiwhi te ngaohiko putanga kei te ki pulsations iti.

Me pēhea te ki te maeneene i te pōkare i kaha te faaafaro i?

Ko te kounga o te ngaohiko whakatikaina heke ki te hua i roto i tona otu'itu'iraa. Ki te whakaiti i te reira, te tono huānga, piki te pūngao ka tukua i te rectifier whakawāteatia ki runga ki whakamutunga o tona take.

I roto i te hoahoa, he rectifier ngōhiko piriti ki te pūnga hono i roto i whakarara ki te kawenga whakamutunga. tīpakohia tōna kaha rokiroki kei i runga i te nāianei utanga rānei. A, no te tono he pini te tohutohutia te pūnga. I waenganui i ngātere (ka kore e ratou), kua hoatu he kawenga ngaohiko.

Ka rite ki te hua o te whakaene putanga tātari ngaohiko riro nui me whakatata te uara o te uara kaha tīwera whakatikaina.

e kore e taea te whiwhi tētahi ngaohiko pai i te putanga o te tātari tika ki te rere o te pūnga i waenganui ngātere. Tikanga, He whakaaetia enei pulsations. Ka taea te heke ratou na roto i te whakanui ake i te āheipuringa o te pūnga iahiko.

Ki te whakamahia te pūpoapoa whakaene te, kua hono te reira i roto i te raupapa ki te kawenga. Ko te ara iahiko tātari ngā ngā inductors me pūnga iahiko.

Construction o te piriti ngōhiko

mahi te piriti pūrere māmā te mā te p motuhake adhesions. hua te ahumahi hanganga nukurau kotahi e te hunga iti i roto i te rahi me te iti. I tua atu, kei te ki āu ratou te p ki ngā āhuatanga ōrite, e taea ana ki a ratou mahi ki te wera taua. faarahi tenei te tika o te ara iahiko ngōhiko piriti rectifier.

Ko te painga o te piriti ngōhiko o te āhuatanga takitahi ko te kaha ki te hanga, ka hemo tetahi o ratou. Ko te whakaminenga ano hoki kua ki te whakakapi rawa. He onge hape i roto i reira, no te mea tika e ki āu nga mea timatanga.

rectifiers Power

e kore e Pūrere e pau te nāianei nui, te nuinga kua powered e 220 V. whakaaro Direct hono, mai te mea iti, he nāianei te ngaohiko e hiahiatia ana mo te iahiko hiko - tamau. Na ka whakamahi te whāurutau AC.

Ngaohiko tuku iho e te hiko, e hanga hoki he wehe galvanic i waenganui i nga mekameka kai tuatahi, me te tuarua. te whakaiti i tenei te mōrea o te ru hiko, me te tiakina e te taputapu ka he poto-taiawhio i roto i te ara iahiko.

whāurutau Modern mahi i roto i te nuinga o te wā i runga i te ara iahiko transformerless māmā kahore wehe galvanic, horomia ai te te mana i te taikaha e te pūnga.

Taraiwa te piriti ngōhiko 12 volts: ako me te huihui

Kei te supply te mana o e rua kōwae, te wahi i te tuatahi - he hiko taahiraa-iho, me te tuarua - te piriti ngōhiko e faafariu tetahi momo o ngaohiko ki tetahi.

Tīpakohia hiko e tika ana. Ko te tuatahi awhiowhio ki te pourewa. Me waiho tona ātete te nui. Na roto i te haere tonutanga He pito multimeter hiahiatia i roto i te aratau resistance inenga. Na i reira e te tahi atu faaipoipo me tohu i hanga.

Kei te tukua ki te tuatahi awhiowhio te 220 V. Na te iritihia te hei whakamatau ki te aratau inenga tauutuutu ngaohiko me ine te ngaohiko i runga i te tahi atu kopiko. Tīpakohia kotahi ranei hurori 10 V. He mea nui e ko te ngaohiko 12 V, mai te tātari kahapupuri i muri i te nui haere te reira i te 18%.

whakaritea te hiko te mo te kaha e hiahiatia ana, ka tangohia te rakau e 25%.

4 ngōhiko miro i roto i te piriti ngōhiko me mutu propaivayutsya. Na ka te hono te ara iahiko, i runga i te hono i te pūnga putanga ki 25 V me 2200 MF (kawehiko) me manatoko i roto i te mahi.

Transformerless taiawhio o nga volts ngōhiko piriti rectifier 24

I roto i te mahi runaruna whakamahia whānuitia supply te mana te mana-iti, kahore transformers.

Power supply 220 tukua te roto i te C1 whakataimaha pūnga. Kei te rectifier o te p VD1, VD2 me te p Zener VD3, VD4. Hei whakakore ongo nāianei i roto i te piriti honotanga te pūnga te mana i roto i te raupapa ki whakaturia he parenga whāiti nāianei te ātete o te 50-100 ohms. I roto i te tikanga ki te ruke i te pūnga ka pakaru iahiko, hono i roto i te whakarara taua 150-300 iahiko kohm.

whakaturia te ara iahiko putanga te pūnga whakaene te āheipuringa o 2000 PF.

hanga te kōrero galvanic kore te ati o te ru hiko.

tono

Tono o te piriti ngōhiko he tino whānui, me te momo:

• rama (LED me rama kōrekoreko);
• pūrere hiko kia inea te;
• wae mana supply o taputapu hiko;
• supply mana ahumahi, mana me te peihana.

Me pēhea te ki te whiriwhiri i te ngōhiko mo te hanga i te piriti ngōhiko?

Ko te paearu kōwhiringa matua ko te ngaohiko me te nāianei i nei e kore te te ngōhiko overheated. I roto i te tika whakaurua runga taka ngaohiko o e pā ana ki 0.6 V, rite te mea he parenga ā-. Ko te ngaohiko whakamuri e whakakeke ana te ngōhiko waho tomo i te aratau wehenga waiariki, me te hiko, kua he tetahi rohe. Ki te hangaia reira mo te 220 V, e te reira kararehe o kahore iti iho i te 25%. Ko he reira pai ki te tango i nui reira nui ki te te tiaki ki ongo aho-mana kōpeka.

Kei te tangohia ano hoki o nāianei i te rāhui. Ki te tika, whakarato reira he whakamahana meangiti.

Hoki kōwhiringa matau o te tepu tohutoro he p me piriti ngōhiko.

Manufacturers piriti ngōhiko

I roto i te āhuatanga mō te rama tu raupapa rectifiers 1N4007 me MS250 hangaia e Diotec. E hangaia ratou hoki ngaohiko ki runga ki te 1000 V. I roto i te take tuatahi, ngā te mania ngōhiko piriti o wha p whakarite i runga i te poari ara iahiko, me te i roto i te tuarua tukua atu rite te huihui kiato. Ahakoa te 1N4007 raupapa pono i roto i te mahi, whakaora whakaminenga MS250 taimaha me te tapuwae. Ahakoa tenei, tonu te raupapa o 1N4007 tono tiketike, rite kua maturuturu iho te utu kia nui e te nuinga whakaritea e te utu o nga whakatau o te parahi.

tonu hangarau ahumahi o te piriti raupapa ngōhiko MS. Na 4 katoa o te piriti karaihe e tāuta tahi, e faarahi tona ātete pāmahana tika ki te tawhā taurite.

heke tika rectifier ki te whakanui ake i ambient pāmahana. faatiti'aifarohia tenei raruraru e te raupapa pūrere B250S2A tātai i runga i te nāianei o 2.3 A me 0.7 te transmissive i 125 ° C.

Te nuinga o ngā kaiwhakanao hoko p, taunga nei rectifiers rite. whai wāhi te kamupene i roto i te hanga katoa Diotec, i te hanga o tioata ki huihui me te mōkihi.

Ko tētahi atu ao kamupene ārahi - IRF - roaa hangarau ahurei whakaiti te rahi o ngā wāhanga, te whakapai ake i te whakawhitinga wera, te whakanui ake i te tōtika o te hangarau Semiconductor. Ko ia te kotahi anake e hua wāhanga mo te huringa faafariuraa pūngao katoa.

mutunga

whakamahia te ara iahiko o te rectifier ngōhiko piriti e i roto i te taputapu hiko katoa. Me te tono rectifier poipoi-tonu, he nui, pai atu i kotahi-wā nei āhuatanga. Tirohia tetahi o ratou e taea e takitahi prozvoniv ia ngōhiko.
