I ka mea hana a me ka pae'ōnaehana rula o ka diode alahaka rectifier huakai kaapuni

Alternating uila au i ua hoohuliia i ka lāʻau ikiʻai wale DC ma ka hoʻohana 'ana o kūikawā lolouila i puhi ai - diode na alahaka. Diode alahaka rectifier huakai kaapuni a ua maheleia i mau wale nō: hoʻokahi-pae, a ekolu-pae.

Ma ka papa kuhikuhiE rectifier hehee ai mea he diode. Structurally, ia mea he papa o ka mea uholo uila inoaia me nāʻokoʻa conductivity cii. A hiʻona mea he unilateral e hooholo ia ana o ka uila papa, ke kaumaha ma muli o ka olelo o ka pele.

'Ole a me ka hana ana o ka rectifier diode nānā' ana i nā hiʻona o ka mea uholo uila pn hoʻololi ma waena o nā cii. Kona ia'ku hilinaʻi nui ma luna o ka polarity o ka mea mawaho anakahi uila. I kekahi manawa, ia mea nui, i loko o nā - iki.

Ka hookahi-pae diode alahaka

I ka wā o ka hoʻokomo o - AC sine nalu anakahi uila ma kela a me keia hapalua kalapona o ka papa hele ma ka paʻa o diodes a me ka'ē aʻe paa hou mai la. E like me ka hopena, i ka auoiaea kaapuni i hanaʻia o ka diode uwapo rectifier ripple anakahi uila me ke alapine (frequency) elua manawa nui ma mua ma ka muliwai.

Ka ekolu-pae alahaka huakai kaapuni

Keia huakai kaapuni a hoʻohana diode hapa-alahaka rectifiers. Na ia auoiaea anakahi uila ua loaa me ka liʻiliʻi pulsations.

Pehea e nāʻalā mai i ka ripple ma straightening mana?

Ka mea e like ai o ka rectified anakahi uila emi me ka hoomahuahua i loko o kona pulsation. I ka ho'ēmi i ia, pili oihana mua, loaa ikehu wā a pau loa, mai ka rectifier i hooakea ai ma luna o hoopau wale o kona waiho 'ana.

I ke kiʻikuhi, he diode uwapo rectifier me ka mea pihana e pili ana ma ka laua me ka hope haawe ana. Kona pūnaewele nona iho ua wae ke kaumaha ma muli o ka haaweʻikena. I ka lāʻau ikiʻai wale ana i ka mea pihana ua kauoha aku la i. Ma waena o ka lāʻau ikiʻai (ia ka mea, i ole), ka mea, ua haawiia mai i ke anakahi uila haawe ana.

E like me ka hopena o ka smoothing Kānana ia auoiaea anakahi uila lilo nui, a hoʻokokoke mai ka waiwai o ka rectified ikaika hawewe waiwai.

An maikaʻi anakahi uila ma ka auoiaea o ka Kānana hiki ole e loaa no i ka hookuuia ana o ka mea pihana ma waena o ka lāʻau ikiʻai. Nō kāu, i kēia mau pulsations 'ana. Ka mea hiki ke ua hoʻemi ma ka hoʻoulu i ka capacitance o ka mea pihana.

Inā ka smoothing inductor ua hoʻohana 'ia, ka mea, ua pili i ka moʻo me ka haawe ana. Ka hui Kānana kaapuni nā inductors a me capacitors.

Ieoaeunoai o ka diode alahaka

Ke simplest lima kūlana kiʻekiʻe alahaka, ua hana Via kaawale diodes adhesions. Ka hana produces monolithic nā hale i mea uuku i ka nui a me ka ho'ēmi. Eia hou kekahi, ua like ka mea, diodes me ka like 'ano, e leie aku ia lakou, e hana me ka ia wela. Kēia maoli i ka pono o ka diode alahaka rectifier huakai kaapuni.

I ka pomaikai o ka diode uapo o ke kanaka hehee wale o ka hiki i ka hana hou, ka wā i kekahi o ia ke aloha. hoopakele mai no hoi i ka ahakanaka e e auou caiaiai loa. Hewa i loko o ka mea e pohihihi keia, no ka mea, e pono i nā kumu like.

Power rectifiers

Mea maalea, e hoʻopau i ka nuiʻikena, nō kāu e manaʻia e 220 V. Direct manaʻo ka mea, i pili, mahope mai o ke anakahi uila koi 'ia no ka uila i puhi ai mea liʻiliʻi, heʻikena - ikaika. A laila, e hoʻohana i ka AC mea hoʻopili.

Anakahi uila kuu iho ma ka mea hoʻololi uila, a hoi i ka mea galvanic hoʻokaʻawale ma waena o ka iniiaiie a me ka haumāna eʻai nā kaula. Kēia ho'ēmi i kā ka pilikia o ka uila hawewe, a hoomaluia ma ka hoʻomākaukauʻia ka wā i ka pōkole-kaapuni i loko o ka huakai kaapuni.

Hoikehonua, adapters hana ma ka hapanui o na hihia ma ka Nohie transformerless kaapuni me galvanic hoʻokaʻawale, kahi o ka mana oi ke kemu ma ka mea pihana.

E hoohauhee ana i ka diode uwapo 12 volts: ke aʻo a me kaʻaha kanaka

Ka mana lako he o mau modules, ma ka mua - no i koe-ia mea hoʻololi uila, a me ka lua o ka - he diode uwapo i pio kekahi 'ano o ke anakahi uila i kekahi.

I koho pono mea hoʻololi uila. Ke iniiaiie o Kahualoa Kokohi mea me heʻia. Kona ia'ku pono ia i ka mea nui. By ka hoʻomauʻana multimeter makemake welau i ka ia'ku ana ano. A laila, loaʻa nō nā Leomakana, a i kaʻaʻai.

Ua lako i ka iniiaiie o Kahualoa Kokohi 220 V. A laila, ua unuhi i kaʻia i alternating anakahi uila ana 'ano i loko, a me nā bato ke anakahi uila ma luna o ka mea'ē aʻeʻanuʻu. E koho i hoʻokahi a pōkaʻa 10 V. He mea nui i ke anakahi uila i 12 V, mahope mai o ka capacitive Kānana ma hope o ka mea, ua hoomahuahua ia ka 18%.

Ka mea hoʻololi uila Ua like no ka mana makemake, alaila, i ka holoholona ua ia e 25%.

4 hilo diode i loko o ka diode alahaka, a me ka welau a propaivayutsya. A laila, ua pili i ka huakai kaapuni, ma ka auoiaea mea pihana ua pili i 25 V a me 2200 mF (electrolyte) a hōʻoia i ka hana.

Transformerless kaapuni o ka diode alahaka rectifier 24 volts

Ma aeoaeuneiai hana hoʻomano hoʻohana haʻahaʻa-mana mana lako ole transformers.

Power lako 220 ua lako ma ka ballast mea pihana C1. Ke rectifier ninoieo o diodes VD1, VD2 a me Zener diodes VD3, VD4. E hoʻopau pono kēia ma ka uwapo ai pili aku i ka mana mea pihana ma ka moʻo me kaʻikena ke kaupalenaʻana mea pale mū holapū ua hoonoho ia'ku o 50-100 ohms. I mea e ia, wawahi kaapuni, e pili ana ma ka laua ia mea 150-300 kohm mea pale mū holapū hookuuia ka mea pihana.

Na ia auoiaea huakai kaapuni a ua hoʻonoho smoothing mea pihana o 2000 pF.

Ka nele galvanic kamailio ana o ka hana i ka pilikia o ka pila kŰia.

palapala noi

Noi o ka diode alahaka ka loa ka laula, a me ka e lauwili:

• Ika (LED a me kukui hāweo kukui);
• uila metering manao ona;
• mana lako huahelu o ka uila lako a pan;
• hanalima mana lako, hooponopono a me nā ipu.

Pehea e koho i kekahi diode no ka hana ana i ka diode alahaka?

I ka papa kuhikuhiE koho ana hoʻohālike i ke anakahi uila a me ka pono ma i ka diode ua ole overheated. I kauoha inclusion ma luna iho, e hina ia anakahi uila o ma kahi o 0,6 V, e like me ka mea i he na e kū'ē'ē mai. Ka aʻe anakahi uila i ka diode, pale aku la me ke komoʻana i ka thermal a me ka uila hālāwai hope? Aaeei, i ka kekahi kali. Inā ka mea, ua papahana no 220 V, ka mea i heluʻia o ka ole e emi malalo o 25%. Akā, ia mea maikaʻi, e lawe ia nui kupono e hoʻopale ai i ku e accidental mana-laina kēia.

O kēia ua hoi ia mai ke koena. Inā pono, ka mea, ua 'oi aku ke anuanu maila radiator.

No ka pono kīvila o ka maopopo kahi papaʻaina, he diodes a me diode na alahaka.

Manufacturers diode na alahaka

Mawaena o na kumu no ka ho'ā ku nei rectifiers moʻo 1N4007 a me MS250 ua hanaʻia e Diotec. Ka mea, i papahana no ka voltages i ka 1000 V. Ma ka hihia mua, ka diode uwapo kaapuni ninoieo o ka eha diodes hoonohonoho i ka huakai kaapuni papa, a ma ka lua o ka mea, ua hōʻike mai iā ia e like me ka olelo hoopomaikai i ua ahakanaka la. ʻOiai ka hopena ua 1N4007 ike loea ma ka hana, ahakanaka MS250 hoopakele kaumaha a me ka footprint. I loko nō o kēia, he moʻo o 1N4007 koi koe kiʻekiʻe, e like me ke kumu kuai i haule iho nei, ua nui i uaʻano nui nānā 'ana i ka lilo o ka hopena o ke keleawe.

Manufacturing enehana o ka MS puke diode na alahaka mau. Ano a pau 4 o ke aniani alahaka Ua hoʻouka kekahi pu, a maoli he kona wela ia'ku aie i ka uniformity kiko'î.

Pono rectifier emi me ka māhuahua Ambient mahana. Keia pilikia ua Wehewehe i nā hāʻina ma ka mea B250S2A puke pōpilikia ma luna o ka papa o 2.3 A a me 0,7 A transmissive ma 125 ° C.

Ka hapanui o Manufacturers kuai diodes, kahi i kau ai e hoomakaukau ai rectifiers. Ka lehulehu ua komo i loko o Diotec holoʻokoʻa? Iecaianoaaiiuo, mai ka hana o nā pōaka, e hoakoakoa ia a me ka pūʻolo helu.

Kekahi ao e alakai poʻe - IRF - paʻa kū hoʻokahi loea emi ka nui o nā māhele, hoʻoikaika 'ana i ka wela hoololiia ana, mahuahua ka ka hoʻokōʻana o ka' enehana mea uholo uila. Ua o ka mea wale nō kekahi e produces eiiiiiaiou no ka mea holoʻokoʻa ikehu huli ana kalapona.

ka hopena

Ke kaapuni ana o ka diode alahaka rectifier ua hoʻohana 'ia i loko o nā mea a pau uila lako a pan. E pili piha-nalu rectifier, o kona ano ua nui maikaʻi ma mua o hookahi-manawa. E hōʻoia i kekahi o ia mau mea hiki e kū kaʻawale prozvoniv kēlā me kēia diode.
