Hloov cov khoom siv hluav taws xob muaj ob hom kev cuam tshuam kev sib txuas
Switching fais fab mov cuam tshuam coupling muaj ob txoj kev: conduction coupling txoj kev, hluav taws xob coupling txoj kev.
Kev sib txuas ua ke yog ib txoj hauv kev sib txuas tseem ceeb ntawm qhov chaw thiab cov khoom siv rhiab heev. Kev sib txuas ua ke yuav tsum yog nyob rau hauv qhov teeb meem tsis zoo thiab cov khoom siv rhiab ntawm qhov muaj qhov ua tiav ntawm kev sib txuas hauv Circuit Court, electromagnetic thab plaub raws li kev sib txuas ntawm cov khoom siv hluav taws xob los ntawm qhov tsis zoo los xa cov hluav taws xob cuam tshuam rau cov khoom siv rhiab, electromagnetic cuam tshuam. Raws li nws cov coupling hom yuav muab faib ua circuit coupling, capacitive coupling thiab inductive coupling. Nyob rau hauv lub switching fais fab mov, peb hom coupling no muaj nyob rau tib lub sij hawm, interconnected.
1. Circuit Court coupling
Circuit Court coupling yog feem ntau, txoj kev yooj yim tshaj ntawm conduction coupling. Muaj ntau hom:
1) ncaj qha conductive coupling hlau los ntawm ib puag ncig ntawm lub hav zoov ntawm kev thab plaub, uas yog, khaws lub zog thab plaub thiab coj raws li cov hlau mus rau lub Circuit Court thiab ua rau cuam tshuam rau lub Circuit Court.
2) kev sib txuas impedance vim muaj ntau tshaj ob lub circuits muaj ib qho impedance, thaum tam sim no ntawm ob circuits ntws los ntawm ib qho impedance, Circuit Court ntawm tam sim no nyob rau hauv ib qho impedance ntawm voltage tsim nyob rau hauv Circuit Court yuav cuam tshuam rau lwm yam Circuit Court, uas yog qhov sib txuam impedance coupling. Tsim cov impedance sib txuas tsis zoo ntawm lub hwj chim tso zis impedance, qhov impedance ntawm lub ntiaj teb hlau, thiab lwm yam.
2. Capacitive coupling
Capacitive coupling tseem hu ua hluav taws xob coupling, vim yog ob lub voj voog ntawm qhov hluav taws xob qhov hluav taws xob yog qhov loj ntawm qhov nqaim mem tes, muaj cov kab mob parasitic capacitance nruab nrab ntawm cov zaus, kom cov nqi hluav taws xob los ntawm cov kab mob parasitic cuam tshuam rau lwm ceg.
3. Inductive coupling
Inductive coupling tseem hu ua magnetic coupling, muaj kev sib nrig sib inductance ntawm ob lub voj voog, thaum qhov cuam tshuam los ntawm cov khoom siv hluav taws xob, cov hlau nplaum tsim los ntawm qhov tam sim no los ntawm kev sib nrig sib txuas ntawm cov teeb liab nyob sib ze los tsim kev cuam tshuam.
