Isticmaalka aasaasiga ah ee toosiyeyaasha silikon ee caadiga ah waa hagaajinta kontoroolka. Wareegga toosiye ee la yaqaan waa wareeg toosiye aan la koontarooli karin. Haddii diode lagu beddelo toosiye kontorool oo silikoon ah, wareegtada toosiyaha ayaa la samayn karaa. Mid ka mid ah hal-waji-hal-waji badh-mawjad-mawjada ugu fudud ee la xakamayn karo wareegga toosiyaha. Inta lagu jiro wareegga nuska togan ee danabka AC sinusoidal u2, haddii korantada kontoroolka ee VS aanu gelin kicinta garaaca wadnaha ug, VS weli lama dami karo. Kaliya marka u2 uu ku jiro wareegga togan ee nuska iyo kicinta garaaca garaaca wadnaha ayaa lagu dabaqaa korantada kontoroolka, thyristor ayaa kiciyay in la shido. Haddii ug uu goor hore yimaado, thyristor-ku goor hore ayuu shidmi doonaa; Haddii ug uu soo daaho, thyristor-ku wuu shidmi doonaa goor dambe. Beddelka wakhtiga imaatinka ee garaaca garaaca ug ee tiirka kantaroolka, celceliska qiimaha ul ee tamarta wax soo saarka ee culeyska waa la hagaajin karaa. Tignoolajiyada, wareegga kala bar ee hadda beddelka ah ayaa inta badan loo dejiyaa sida 180 °, kaas oo loo yaqaan xagal koronto. Sidan oo kale, wareeg kasta oo badhkii togan ee u2, xagasha korantada ee laga soo bilaabo qiimaha eber ilaa wakhtiga garaaca garaaca wadnaha waxaa loo yaqaan xagasha kantaroolka α; xagasha korantada ee thyristor ku qabto wareeg kasta oo badhkii togan waxa loo yaqaan xagasha conduction θ. Sida iska cad, α iyo θ labadaba waxaa loo isticmaalaa in lagu muujiyo dhaqdhaqaaqa ama xannibaadda baaxadda thyristor inta lagu jiro wareegga nuska ee danabka hore. Adigoo bedelaya xagasha kontoroolka α ama xagasha korantada θ, celceliska qiimaha ul ee garaaca garaaca garaaca DC ee culeyska waa la bedelayaa, hagaajinta la xakameyn karo waa la xaqiijiyay. Wareegga hagaajinta buundada, laba diode oo keliya ayaa loo baahan yahay in lagu beddelo toosiyeyaasha silikoon ee la kontaroolo si loo sameeyo wareegga toosiyaha kontoroolka buuxa.
