Rectifier diode - malongosoledwe a magawo ndi makhalidwe a

Rectifier diode - pazipangizo kwa akatembenuka panopa zonse mu alternating panopa. Izi ndi ziwiri elekitirodi chipangizo, amene ali yopitira yokha (unipolar) magetsi madutsidwe. Rectifier diode zipangizo michenga yopangira zida zamagetsi ndi otchedwa diode milatho (pamene diodes anayi ogwirizana diagonally awiriawiri Ngati munthu) m'malo ignitron ndi zingalowe diode.

Zotsatira za rectification wa alternating panopa ndi kusintha mu kusintha okhazikika kumachitika pa michenga yopangira zida zamagetsi zitsulo zitsulo-michenga yopangira zida zamagetsi kapena otchedwa zinthu zosiyanasiyana za dzenje kusintha zina ndi timibulu (mwachitsanzo, pakachitsulo, germanium, selenium, okusayidi mkuwa). timibulu oterewa nthawi zambiri maziko chipangizo.

Michenga yopangira zida zamagetsi rectifier diode ntchito magetsi a pakompyuta ndi zipangizo zamagetsi. Ndipotu ataweramuka - kusintha alternating zikusinthira (voteji) kuti panopa wa polarity chimodzi (kugunda DC). Mtundu wa rectification muyenera pa luso kwa kutsegula ndi kutseka madera magetsi, kusintha ndi kudziwika chizindikiro magetsi ndi nyemba, ndi zina zambiri masinthidwe ofanana. Chotero makhalidwe diode monga ntchito, magawo bata, mphamvu mphambano pn si kupereka kwa iye amafuna zapadera.

Chotero chipangizo ali ndi ena magawo magetsi ndi makhalidwe a diodes ndi:

- patsogolo voteji pa anati phindu zikusinthira (anatengedwa kufunika pafupifupi) ;

- chigamulocho panopa pa mtengo kuperekedwa kwa voteji n'zosiyana ndi kutentha (pafupifupi phindu) ;

- matalikidwe mfundo kwa pazipita chovomerezeka n'zosiyana voteji;

- phindu avareji patsogolo panopa;

- pafupipafupi mfundo popanda mode kuchepetsa;

- kukana.

Rectifier diode kawirikawiri chidule chabe wotchedwa rectifier. Monga mbali ya dera, iyenera kukana mkulu panopa amene ukuyenda mwa njira imodzi ndi otsika zomwe akupezeka malangizo iwowo. Izi zimayambitsa rectification panopa.

Mu chipangizo monga diode rectifier, mokwanira ang'onoang'ono pafupipafupi osiyanasiyana. Opaleshoni pafupipafupi ntchito mafakitale ngati chipangizo ndi AC kwa DC kutembenuka 50 Hz. Malire pafupipafupi akuti ndi zosaposa 20 kHz.

Rectifier diode monga chipangizo zamagetsi zikhoza kugawidwa m'magulu angapo mtengo wofanana ndi mtengo avareji pazipita panopa mwachindunji. Izi otsika mphamvu diode (0,3 mikuza mawu), mphamvu sing'anga (kuchokera 0,3 A 10 A) ndi ntchito katundu (mphamvu) rectifier diodes (amperes oposa khumi).

Magawo waukulu zipangizo ngati zamagetsi monga rectifier diode, ndipo ayenera akuphatikizapo opaleshoni osiyanasiyana kwa kutentha yozungulira (izo kawirikawiri ranges ku -50 kuti +130 madigiri Celsius chifukwa ambiri mtundu diode - pakachitsulo) ndi kutentha pazipita thupi (a zosiyanasiyana magawo, malingana ndi mphamvu ya kuikidwa ndi Mlengi).
