Ukulungiswa okulawulwayo
Olona setyenziso lusisiseko lwee-thyristors eziqhelekileyo lilawulwa ukulungiswa. Isiphaluka esiqhelekileyo sokulungisa kwakhona sisiphaluka esingalawulekiyo. Ukuba i-diode ithathelwe indawo yi-thyristor, inokwenza isekethe elawulekayo yokulawula, inverter, umgaqo wesantya semoto, uchuku lwemoto, iswitshi engadibaniyo kunye nolawulo oluzenzekelayo. Kwinjineli yombane, umjikelo wesiqingatha sokutshintshana okwangoku uhlala useta njenge-180 °, ebizwa ngokuba yi-angle yombane. Ngale ndlela, kumjikelo ngamnye wesiqingatha esifanelekileyo se-U2, i-engile yombane enamava ukusuka kwixabiso le-zero ukuya kumzuzu we-pulse pulse ibizwa ngokuba yi-angle angle α; i-engile yombane apho i-thyristor iqhuba khona kumjikelo ngamnye wesiqingatha esihle ibizwa ngokuba yi-angle conduction θ. Ngokucacileyo, zombini α kunye θ zisetyenziselwa ukubonisa ukuqhuba okanye ukuthintela uluhlu lwe-thyristor ngexesha lomjikelo wesiqingatha sevolthi yangaphambili. Ngokutshintsha i-engile yolawulo α okanye i-engile yokuqhuba θ, ixabiso eli-avareji ye-UL yombane we-pulse DC kumthwalo utshintshiwe, kwaye ulungiso olulawulwayo luyafezekiswa.
Iswitshi ekunxibelelana nayo
Umsebenzi we-thyristor ayisiyokulungisa kuphela, inokusetyenziselwa ukutshintshela ngaphandle kokunxibelelana ukuvula ngokukhawuleza okanye ukucima isekethe, uqaphele ukuguqulwayo kwangoku ngokuthe ngqo ukuya kutshintsho lwangoku, kwaye utshintshe ubungakanani obunye bokutshintsha ngoku ukuya kwesinye isihlandlo sokutshintsha yangoku, nezinye ezininzi.
