Ib qho ntawm cov ntsiab lus hauv cov khoom siv hluav taws xob niaj hnub no yog lub diode. Nws yog siv nyob rau hauv circuits qhov twg AC rectification yog xav tau, thiab yog siv nyob rau hauv yuav luag tag nrho cov khoom siv hauv tsev. Koj tuaj yeem pom nws hauv TV, khoos phis tawj, tub yees, daim kab xev kaw, thiab lwm yam. Nws kuj yog siv dav hauv kev lag luam hluav taws xob, yog ib feem ntawm cov circuits uas tswj cov txheej txheem thev naus laus zis. Hwj chim diodes yog siv nyob rau hauv semi-tswj thyristor converters. Raws li lub hauv paus ntawm lub diode, lub thiaj li hu ua Hertz Circuit Court tau sib sau ua ke, uas yog hu ua tus choj diode. Kev sib txuas ntawm diodes nyob rau hauv ib tug choj Circuit Court ua rau nws muaj peev xwm mus kho ib tug alternating voltage thiab hloov mus rau ib tug pulsating ib tug, uas yuav tau stabilized thiab rectified siv voltage stabilization circuits thiab capacitors. Raws li qhov tshwm sim, qhov hluav taws xob tsis tu ncua tuaj yeem tau txais ntawm cov khoom siv no.
Thaum lub sijhawm Leo Hertz, nws muaj teeb meem siv tus choj diode, txij li lub sijhawm diodes yog raj diodes. Muab plaub lub teeb rau AC rectification ib zaug yog yam tsawg kawg nkaus, thaum lub sijhawm ntawd lawv kim heev. Qhov xwm txheej tau hloov pauv loj heev nrog rau qhov tshwm sim ntawm semiconductorCov khoom siv, lawv muaj ntau dua compact thiab pheej yig dua.
Sib dhos diode
bridge tuaj yeem ua los ntawm koj tus kheej, piv txwv li, rau koj lub tsev kuaj mob. Txhawm rau ua qhov no, peb xaiv plaub lub diodes nrog qhov tso cai rov qab voltage ntawm 400-500 Volts. Peb txuas cov cathodes ntawm ib khub ntawm diodes ua ke - qhov no yuav yog qhov txiaj ntsig zoo ntawm tus choj. Peb kuj txuas cov anodes ntawm ob khub ua ke - qhov no, feem, yog qhov tsis zoo. Tam sim no peb muab ob khub ua ke rau hauv ib lub voj voog, ob qhov kev tso tawm ntxiv tuaj yeem muab tau nrog kev hloov hluav taws xob. Ntawm qhov tso zis ntawm tus choj diode, peb solder lub ncov qaumteb qabteb capacitor thiab thaum uas tig mus rau nws - qhov paug tsis kam. Nws tig tawm tus choj diode uas tuaj yeem ntsia tau rau ntawm lub desktop thiab txuas nrog los ntawm qhov sib txawv ntawm qhov ua haujlwm siab rau lub ntsiab. Cov zis voltage ntawm xws li ib tug ntaus ntawv yuav raug tswj los ntawm xoom mus rau lub amplitude tus nqi ntawm cov mov network, uas yog heev yooj yim rau powering low-power circuits thaum commissioning los yog tsim ib tug siv voltage.
Tsis tas li ntawd, tus choj hluav taws xob siv hauv lub tsheb, ntawm no yog siv lub tshuab hluav taws xob diode choj. Nws ua hauj lwm los hloov cov hluav taws xob hloov hluav taws xob uas lub tshuab hluav taws xob tsim tawm mus rau hauv qhov hluav taws xob tas li uas siv hauv txhua lub tsheb. Tsis tas li qhov hluav taws xob kuj tseem xav tau los rov them lub tsheb roj teeb. Qhov tsis ua tiav ntawm ib lub caij ntawm tus choj diode ua rau kev ua haujlwm tsis ruaj khov ntawm tag nrho lub voj voog.
DC vuam kuj yuav tsum tau sivdiode choj. Nyob rau hauv cov ntaub ntawv no, diodes ntawm lub hwj chim ntau dua nyob rau hauv ib lub tsheb yog siv, thiab nrog ib tug loj tso cai rov qab voltage nqi. Tus choj diode rau lub tshuab vuam tuaj yeem sib sau ua ke ntawm nws tus kheej siv cov diodes muaj zog. Cov chav kawm ntawm diodes raug xaiv nyob ntawm qhov khoom siv hluav taws xob tau txais los ntawm vuam transformer.
