Oorsig van Fasebeheer tiristor

'n Fasebeheer tiristor, dikwels na verwys as 'n triac of SCR (Silikon beheerde gelykrigter) in sekere toepassings, is 'n halfgeleiertoestel wat gebruik word om die hoeveelheid krag wat aan 'n las gelewer word te beheer deur die fasehoek waarteen die WS-golfvorm toegelaat word om te gelei, aan te pas. Hierdie metode van beheer staan ​​bekend as fasehoekbeheer of bloot fasebeheer. Fasebeheer-tiristors word wyd gebruik in verskeie toepassings wat presiese regulering van elektriese krag vereis, soos beligtingsdimmers, motorspoedkontroles, temperatuurbeheerders, en meer.

Kenmerke van fasebeheer tiristor

Fasehoekbeheer: Laat aanpassing van die geleidingspunt binne elke halfsiklus van die WS-golfvorm toe, wat presiese beheer moontlik maak oor die gemiddelde krag wat aan die vrag gelewer word.

Hoë doeltreffendheid: Werk met minimale verliese tydens uitvoer, verskaffing van doeltreffende kragbeheer.

Tweerigtinggeleiding (Triacs): Vir AC toepassings, triacs kan stroom in beide rigtings gelei, wat hulle geskik maak vir volgolfbeheer van AC-ladings.

Eenrigtinggeleiding (SCR's): SCR's gelei stroom slegs in een rigting en word tipies gebruik vir halfgolf beheer van AC- of DC-ladings.

Hek-snellering: Geleiding begin wanneer 'n klein stroom op die hekterminaal toegepas word, wat maklike beheer van die aanskakelpunt moontlik maak.

Vergrendelstroom: Een keer geaktiveer, die tiristor hou aan om te gelei totdat die stroom daardeur onder 'n sekere vlak val wat die houstroom genoem word.

Temperatuurgevoeligheid: Werkverrigting kan deur temperatuurveranderinge beïnvloed word, wat termiese bestuursoorwegings in ontwerp vereis.

Spanning en stroomgraderings: Beskikbaar in 'n wye reeks spanning- en stroomgraderings om aan verskillende toepassingsbehoeftes te voldoen.

Geraas Generasie: Kan elektromagnetiese interferensie genereer (EMI), wat behoorlike filtrasie en afskerming in sensitiewe toepassings vereis.

Beskermingsmeganismes: Sluit dikwels ingeboude beskerming teen oorspanning en oorstroomtoestande in om die toestel en gekoppelde stelsels te beskerm.
