Cov Cheebtsam thiab Txoj Cai Ua Haujlwm
Componnets:
● Thyristor (SCR/TRIAC):
Unidirectional lossis bidirectional thyristors (piv txwv li, SCR, TRIAC) ua lub ntsiab hloov pauv.
Tig los ntawm lub rooj vag (G) lub davhlau ya nyob twg thiab ib txwm kaw ntawm xoom tam sim no- hla.
● Trigger Circuit: Tswj lub thyristor tig- ntawm lub sijhawm (piv txwv li, xoom- hla kev sib tw, theem-angle tswj).
● Kev Ntsuas Hluav Taws Xob / Tam sim no: Saib xyuas cov kab sib chaws kom paub meej tias kev hloov pauv hloov pauv (tiv thaiv tsis muaj zog tam sim no).
● Cooling System: Aluminium heat sinks los yog yuam- cua txias (kom dissipate conduction poob).
Hom kev ua haujlwm:
● Zero-Crossing Switching:Triggers conduction at AC voltage zero-hloov kom tsis txhob muaj surges tam sim no (zoo tagnrho rau capacitive/inductive loads).
● Theem-Lub kaum sab xis tswj: kho lub zog thauj khoom los ntawm kev ncua lub kaum sab xis (piv txwv li, dimming, tswj lub cev muaj zog).
