Rectifier diode - inkcazelo parameters kunye iimpawu

Rectifier diode - kwizixhobo ze-elektroniki ukuba zokuguqula lwangoku rhoqo ibe ifildi yangoku. Esi sisixhobo electrode-mbini, nto leyo eye-indlela enye kuphela (unipolar) conductivity zombane. Rectifier diode izinto semiconductor kwaye kuthiwa Iibhulorho diode (xa ilight ezine oxhulumene kwikonw ngekona ngababini xa elinye) kufakwe ignitron kunye cleaner diode.

Umphumo Ukulungiswa alternating current kwaye ukuyijika ibe inguqu esisigxina lwenzeka kwi semiconductor-metal, metal-semiconductor okanye ekuthiwa-electron-umngxuma utshintsho kwezinye ziikristale (umz, lesilicon, germanium, selenium, oxide zobhedu). ziikristale enjalo aphela rhoqo yakha isiseko kwefowuni.

Semiconductor rectifier diode ezisetyenziswa elektroniki, elektroniki kunye nezixhobo zombane. Enyanisweni, lo eqondisa - eli yenguqu alternating current (ombane) ukuya langoku wokwephuka (eliguquguqukayo DC). Olu hlobo nokulungisa kufuneka kwi ezobugcisa lokuvula nokuvala iziphaluka zombane, isenza kunye ubhaqo lwemiqondiso zombane kunye pulses, kunye nezinye utshintshwano ezininzi ezifanayo. iimpawu diode afana yokusebenza, parameters uzinzo, umthamo ezidibanayo PN akanyanzelekanga ukuba bammise kuye naziphi na iimfuno ezizodwa.

Loo isixhobo unalo lombane parameters kunye iimpawu ilight ezithile:

- ombane phambili kwi uthe ixabiso yangoku (uthabathe ixabiso avareji) ;

- reverse zangoku kwi ixabiso elinikiweyo le ombane umva lobushushu (umyinge ixabiso) ;

- amaxabiso awo ukuba ubuninzi umva obuvumelekileyo ombane;

- ixabiso avareji ye yangoku phambili;

- amaxabiso rhoqo ngaphandle imo lokunciphisa;

- ukuxhathisa.

Rectifier diode udla olufinyeziweyo ebizwa nje rectifier. Njengenxalenye zesekethe, oko enokumelana eliphezulu ukuya zangoku ophuma kwicala elinye kwaye ephantsi oko kwenzeka kwicala umva. Oku kwenza a ukulungisa yangoku.

Kwiphakati efana rectifier diode, encinane ngokwaneleyo uluhlu rhoqo. sokuquqa zokusebenza ukwenzela ukusetyenziswa kwimizi isixhobo esinjalo kunye uguqulelo AC ukuya DC 50 Hz. Nciphisa frequency ithathwa kuba ngaphezu kwe-20 kHz.

Rectifier diode njengoko isixhobo electronic zingahlulwa zibe ngamaqela eziliqela ngokwexabiso umndilili yangoku ngqo ubuninzi. Le diode ephantsi amandla (0.3 amps), igunya eliphakathi (ukusuka 0.3 A ukuya 10 A) kunye duty ezisindayo (power) ilight rectifier (amperes ngaphezu kweshumi).

Ipharamitha ezingundoqo izixhobo ezifana electronic ezifana diode rectifier, kwaye kufuneka ibandakanye uluhlu yokusebenza iqondo lobushushu kokugquma i (kudla isusela ukusuka -50 ukuya +130 degrees Celsius ukuba ixhaphakileyo udidi diode - lesilicon) kunye ubushushu bomzimba iphezulu (iintlobo yemida, kuxhomekeke emandleni wokuqeshwa kunye yakowayo).
