Umqalisi othambileyosisixhobo solawulo lwemoto inoveli edibanisa isiqalo esithambileyo semoto, ukumisa okuthambileyo, ukonga amandla okukhanya kunye nemisebenzi emininzi yokukhusela.Eyona nto iqulunqwe yi-thyristors ye-reverse yesigaba esithathu ehambelanayo kunye ne-electronic control circuit edityaniswe kuthotho phakathi kokunikezelwa kwamandla kunye nemoto elawulwayo.Sebenzisa iindlela ezahlukeneyo zokulawula i-angle conduction ye-thyristors yesigaba esithathu ehambelanayo ukwenzela ukuba igalelo lombane weemoto ezilawulwayo zitshintshe ngokweemfuno ezahlukeneyo, kunye nemisebenzi eyahlukeneyo inokuqondwa.

Ngokusetyenziswa okukhulayo kweenjini ezinkulu (5000kW～60000kW)amashishini amakhulu kunye nezixhobo, indlela yokuqala yeenjini ezinkuluuye watsalwa ngakumbi nangakumbi.Ngenxa yokusebenza okuphantsi kwesixhobo sokuqalisa ulwelo akakwazi ukuhlangabezana neemfuno zokuqala zeenjini ezinkulu zomthamo, ukusetyenziswa kohlobo lwe-thyristor (imeko eqinileyo) izixhobo zokuqalisa ezithambileyo sele ziqalisile ukwanda.Kwaye emva koko ukutshintsha izixhobo zokuqalisa ezithambileyo zohlobo lwe-transformer kunye ne-magnetic saturation reactors (elawulwa ngomagnetic) izixhobo zokuqalisa kunye nezixhobo zokuguqula amaza zisetyenziswa ngakumbi ukuqala okuthambileyo kweenjini.Okwangoku, izixhobo zokuqalisa ulwelo zisetyenziswa kakhulu kwiinjini ezincinci (ngaphantsi kwe-5000kW).Kwaye thyristor seriesumqalisi othambileyozisetyenziswa kakhulu kwimoto yamandla aphezulu (ngaphezu kwama-5000KW).
