Rectifier diode - incazelo imingcele kanye nezici

Rectifier diode - idivayisi electronic zokuguqula zamanje njalo ibe zamanje kushintshana. Le idivayisi ezimbili electrode, okuyinto has kuphela eyodwa (unipolar) conductivity kagesi. Rectifier diode ka Semiconductor izinto okuthiwa diode amabhuloho (lapho diodes ezine axhunyiwe ngokuphambeneyo ngababili kwelinye icala) esikhundleni ignitron kanye cleaner diode.

Umthelela ukulungiswa kwananoma kushintshana zamanje bese siguqulwa inguquko unomphela kwenzeka ngesikhathi Semiconductor-metal, metal-semiconductor noma okuthiwa i-electron-imbobo ushintsho kwezinye zinhlayiya (isib, i-silicon germanium, selenium, ithusi oxide). zinhlayiya anjalo ngokuvamile yisisekelo zedivayisi.

Semiconductor rectifier diode elisetshenziswa electronics, electronic kanye namadivayisi kagesi. Eqinisweni, Ehlala - lolu shintsho kushintshana wamanje (voltage) kuya samanje eyodwa polarity (onesigqi DC). Lolu hlobo ukulungiswa kwananoma kudingeka ubuciko ngoba ivula ivala izifunda kagesi, ukushintsha futhi ukuthola amaza kagesi kanye pulses nezinye kugucuka eziningi ezifanayo. diode okunjalo izici ezifana ukusebenza, ukuzinza imingcele, amandla we kokuhlangana PN Awuphoqelekile ukwethula kuye nanoma yiziphi izidingo ezikhethekile.

idivayisi okunjalo has a imingcele ethile kagesi kanye izici diodes:

- voltage phambili ngesikhathi wathi Inani lamanje (ezithathwe inani eliyisilinganiso) ;

- ukuhlanekezela zamanje kunani kunikezwa voltage reverse futhi lokushisa (value isilinganiso) ;

- amagugu amplitude ngokuba eliphelele elivumelekile reverse voltage;

- nenani isilinganiso wamanje phambili;

- imvamisa amagugu ngaphandle imodi ukuncishiswa;

- ukumelana.

Rectifier diode ngokuvamile esifushanisiwe nje ngokuthi i-rectifier. Njengoba ingxenye circuit, it has ukumelana a wamanje yiwo ogelezela kwelinye direction futhi nibe phansi kubo ukuthi okwenzeka kolunye reverse. Lokhu kubangela ukulungiswa kwananoma zamanje.

Ngo idivayisi ezifana rectifier diode, a ngokwanele encane imvamisa ububanzi. Operating imvamisa nokuba angasetshenziswa ezimbonini thuluzi nge AC ukuze DC ukuguqulwa 50 Hz. Umkhawulo imvamisa ubhekwa akukho engaphezu kwengu-20 kHz.

Rectifier diode njengoba zobuchwepheshe zingahlukaniswa zibe amaqembu amaningana ngokuvumelana nenani isilinganiso esiphezulu zamanje ngqo. Lokhu ongaphakeme amandla diode (0.3 Amps), amandla aphakathi (kusuka 0.3 A kuya 10) futhi duty ezisindayo (amandla) rectifier diodes (amperes ezingaphezu kweziyisishiyagalombili nokuba eziyishumi).

Amapharamitha eyinhloko zobuchwepheshe ezifana ezifana diode rectifier, futhi kufanele sifake uhla lokusebenza for the lokushisa kuma (ngokuvamile zokhahlamba kusuka -50 kuya +130 degrees Celsius ukuze ezivamile uhlobo diode - Silicon) futhi izinga lokushisa komzimba esiphezulu (ezihlukahlukene imingcele, kuye amandla aphoyintimenti nomkhiqizi).
