Isilawuli samandla se-SCR, eyaziwa nangokuthi isilawuli samandla se-SCR kanyei-thyristor power regulator, iyisisetshenziswa sikagesi esilawula ukuphuma kwamandla kumasekhethi kagesi.Isetshenziswa kakhulu ezinhlelweni ezahlukahlukene zezimboni nezentengiso ezidinga ukulawulwa okunembile kwamandla.Kulesi sihloko, sizoxoxa ngezimiso zabalawuli bamandla we-SCR.
Izilawuli zamandla e-SCRsebenza ngesimiso sokulawula isigaba.Isebenzisa i-thyristor (idivayisi ye-semiconductor) ukulawula inani likagesi eligeleza kumjikelezo.I-thyristor isebenza njengeswishi evula futhi ivale ngezikhathi eziqondile umjikelezo wamandla ngamunye.Ngokulawula ubude besikhathi i-thyristor ivuliwe, amandla okukhiphayo angahlukahluka.
Ukusebenza kwesilawuli samandla se-SCR kusekelwe ku-isilawuli se-engeli yokudubulaisimiso.I-engeli yokudubula i-engeli i-thyristor eqhuba kuyo phakathi nomjikelezo wamandla ngamunye.Ngokushintsha i-engeli yokudubula, inani lamandla eligeleza kumjikelezo lingalawulwa.I-voltage ephumayo kanye neyamanje ingalawulwa ngokushintsha i-conduction angle ye-thyristor.
Izilawuli zamandla ze-SCR zisebenzisa isistimu yempendulo ukuze zigcine amandla okukhiphayo esezingeni elingashintshi.Isistimu yempendulo iqhathanisa i-voltage ephumayo noma yamanje nesiginali yereferensi futhi ilungisa i-engeli yokudubula yama-thyristors ngokufanele.Lokhu kuqinisekisa ukuthi amandla okukhiphayo ahlala engashintshi ngisho noma umthwalo noma i-voltage yokufaka ishintsha.
Izilawuli zamandla e-SCR zinezinzuzo ezimbalwa ngaphezu kwezinye izinhlobo zabalawuli bamandla.Isebenza kahle kakhulu futhi ingakwazi ukuphatha amanani amakhulu wamandla ngokulahlekelwa okuncane.Ithembekile futhi futhi ingasebenza ezimeni ezinzima.Ngaphezu kwalokho, kulula ukuyilawula futhi ingahlanganiswa ezinhlelweni ezihlukahlukene ze-elekthronikhi.
Ukufingqa, isimiso somlawuli wamandla we-SCR sisekelwe ekulawuleni isigaba se-thyristor.Ngokushintsha i-angle yokudubula ye-thyristor, amandla okukhiphayo angalawulwa.Uhlelo lwempendulo luqinisekisa ukuthi amandla okukhiphayo ahlala engashintshi nangaphansi kwezimo ezishintshayo.I-SCR power conditioner iyisisetshenziswa se-elekthronikhi esisebenza kahle, esithembekile, futhi okulula ukusilawula esisetshenziswa ezinhlotsheni eziningi zezimboni nezentengiso.
