Lub tshuab thyristor yog cov khoom siv hluav taws xob uas qhib thaum hluav taws xob siv rau lub rooj vag, thiab tom qab ntawd tseem qhib, tsis hais txog qhov hloov pauv voltage thoob nws. Txhawm rau kaw ntawm thyristor, nws yog qhov tsim nyog yuav tsum tau kaw lub hwj chim hluav taws xob hauv lub tswj kav.
Cov Lus Qhia
Kauj ruam 1
Hauv qhov DC Circuit, thyristor ua haujlwm ua ib qho chaw cia khoom, zoo ib yam li RS flip-flop. Txhawm rau kom nws ua haujlwm hauv hom no, sib sau ua ke ntawm Circuit Court uas muaj 6 V rectified thiab lim qhov voltage, lub 6 V thiab 0.1 Ib lub teeb ci, thiab thyristor. Muab nws hauv qhov qhib Circuit Court kom qhov anode tau ntsib qhov zoo ntawm lub hwj chim qhov hluav taws xob, thiab cathode tau ntsib qhov muag teeb.
Kauj ruam 2
Tam sim ntawd tom qab thov voltage rau hauv Circuit Court, lub teeb yuav tsis ci, txij li lub thyristor kaw. Txhawm rau qhib nws, coj lub ntsuas tiv thaiv nrog qhov tsis kam ntawm 100 Ohm txog 1 kOhm (nyob ntawm yam khoom) thiab txuas nws nruab nrab ntawm thyristor anode thiab nws cov electrode tswj. Lub teeb yuav taws teeb thiab yuav txuas ntxiv mus rau lub teeb txawm tias tom qab tshem tawm cov thev khoom.
Kauj ruam 3
Muaj ob txoj hauv kev los tua hluav taws. Thawj yog txuas rau lub jumper ntawm qhov anode thiab cathode ntawm thyristor thiab tom qab ntawd tshem nws. Thaum tus jumper tshem tawm, lub teeb tawm mus. Qhov txheej txheem thib ob yog kev txiav tawm thiab tom qab ntawd tig rau lub zog hluav taws xob lossis lub sijhawm luv luv ntawm lub voj voog muab los ntawm nws.
Kauj ruam 4
Lub thyristor coj tus cwj pwm sib txawv ua ke yog tias lub hwj huam hluav taws xob muaj qhov ntsuas tawm, tab sis nws tsis muaj lub lim thiab ua kom muaj qhov hloov ntawm lub tshuab hluav taws xob. Hauv qhov no, lub teeb yuav taws teeb thiab tawm mus tib lub sijhawm nrog kev sib txuas thiab tshem tawm cov resistor ntawm qhov anode thiab tswj electrode. Thov nco ntsoov tias qhov tam sim no hauv qhov kev tswj kav yuav yog tsawg dua li hauv ib qho tswj tau. Yog li, thyristor muaj cov khoom siv kom nrov thiab tso cai rau koj los tswj lub zog loj uas siv lub pob hluav taws xob qis, tib lub sijhawm tiv thaiv kev kub nyhiab ntawm nws cov neeg.
Kauj ruam 5
Siv lub thyristor, koj tuaj yeem tswj hwm lub zog rau hauv txoj kev thauj khoom los ntawm kev siv cov mem tes-dav tes taws los piav. Rau qhov no, lub Circuit Court kuj tau txais lub zog los ntawm qhov chaw uas muaj qhov txuas tawm uas tsis muaj lim. Lub sijhawm ntawm kev muab cov lus qhib ntawm cov pulses mus rau kev tswj cov electrode raug xaiv sib txawv, raws li qhov nruab nrab lub zog xav tau hauv lub nra. Qhov tseeb, nws tsuas yog tig rau ntawm lub zog tag nrho ntawm qhov kev kub ceev, tom qab ntawd hloov tawm kom meej, tab sis vim yog inertia, qhov nruab nrab fais fab hloov ncaj qha.
Kauj Ruam 6
Hauv kev xyaum, nyob rau hauv dimmers (dimmers) kev khiav haujlwm ntawm lub hauv paus ntsiab lus no, tsis yog thyristors feem ntau siv, tab sis triacs muaj peev xwm dhau tam sim no hauv ob qho tib si. Qhov no zam qhov siv ntawm qhov txuas tus choj. Lub neon teeb lossis chav noj mov yog siv los ua ib qho pib rau kev qhib ntse ntawm lub triac, raws li, piv txwv li, hauv daim duab hauv qab no:
