Rectifier diode - da bayanin da sigogi da kuma halaye na

Rectifier diode - wani lantarki na'urar for tana mayar da akai halin yanzu a cikin wani alternating halin yanzu. Wannan shi ne wani biyu-lantarki na'urar, wanda yana daya kawai-hanya (unipolar) lantarki watsin. Rectifier diode na semiconductor kayan da ake kira diode gadoji (a lokacin da hudu diodes suna da alaka diagonally a nau'i-nau'i a daya hali) maye gurbin ignitron da kuma injin diode.

A sakamakon kyautatuwar al'amuran alternating halin yanzu da kuma maida shi a cikin wani m sauyin auku a semiconductor-karfe, karfe-semiconductor ko abin da ake kira electron-rami mika mulki a wasu lu'ulu'u (msl, silicon, germanium, selenium, jan oxide). Irin wannan lu'ulu'u sau da yawa samar da tushen da na'urar.

Semiconductor rectifier diode amfani da lantarki, lantarki da kuma lantarki na'urorin. A gaskiya ma, cikin straightening - wannan canji alternating halin yanzu (ƙarfin lantarki) zuwa yanzu na daya polarity (pulsating DC). Wannan irin gyãrawa bukatar a art for bude da kuma rufe lantarki haihuwarka, ya sauya sheka da kuma ganewa na na'urar sakonni da hatsaisai, kuma domin da yawa wasu irin canje. Irin wannan diode halaye kamar yi, kwanciyar hankali sigogi, da damar pn mararraba ba zamar masa dole ya gabatar da shi da wani musamman da bukatun.

Irin wannan na'urar yana da wani lantarki sigogi da kuma halaye na diodes:

- gaba ƙarfin lantarki a ce yanzu darajar (dauka da talakawan darajar) .

- baya halin yanzu a iyakancen darajar da baya da irin ƙarfin lantarki da kuma yawan zafin jiki (matsakaici darajar) .

- amplitude dabi'u ga iyakar halatta baya ƙarfin lantarki.

- da talakawan tamanin da gaba halin yanzu.

- mita dabi'u ba tare da rage yanayin.

- juriya.

Rectifier diode ne sau da yawa rage tsawon kawai ake kira mai rectifier. Kamar yadda wani bangaren na kewaye, yana da high juriya zuwa yanzu wanda gudana a daya shugabanci da kuma low zuwa ga abin da ya auku a cikin Reverse shugabanci. Wannan sa a halin yanzu gyãrawa.

A wani na'urar kamar wani diode rectifier, a isasshe kananan mita iyaka. Operating mita ga masana'antu amfani da irin wannan na'urar da wani AC zuwa DC hira ne 50 Hz. Yawan mita aka dauke su ba fiye da 20 kHz.

Rectifier diode matsayin na'urar lantarki za a iya raba da dama kungiyoyin bisa ga talakawan darajar matsakaicin kai tsaye halin yanzu. Wannan low ikon diode (0.3 amps), matsakaici ikon (daga 0.3 A zuwa 10 A) da kuma nauyi wajibi (ikon) rectifier diodes (fiye da goma amperes).

Babban sigogi na irin wannan na'urorin lantarki kamar a rectifier diode, kuma dole ta hada da aiki iyaka ga yanayi zazzabi (shi yawanci jeri daga -50 zuwa +130 digiri Celsius domin ya fi kowa da irin diode - silicon) da kuma matsakaicin jiki zafin jiki (a dama sigogi, dangane da ikon saduwa da manufacturer).
