Cov tswv yim ntawm kev hloov hluav taws xob feem ntau yog AC lub zog lossis DC lub zog, thiab cov khoom siv feem ntau yog cov khoom siv uas xav tau DC lub zog, xws li lub khoos phis tawj phau ntawv, thiab cov khoom siv hluav taws xob hloov pauv hloov hluav taws xob thiab tam sim no ntawm ob.
Hloov cov khoom siv hluav taws xob sib txawv ntawm cov khoom siv hluav taws xob linear.Feem ntau ntawm cov hloov pauv hloov pauv siv rau hauv cov khoom siv hluav taws xob hloov pauv hloov ntawm hom puv (saturation zone) thiab tag nrho-kaw hom (tshem tawm tsam).Ob qho tib si muaj cov yam ntxwv ntawm qhov qis dissipation.Kev hloov dua siab tshiab yuav muaj ntau dua dissipation, tab sis lub sij hawm luv heev, yog li nws txuag lub zog thiab ua kom tsis muaj hluav taws xob tsawg.Qhov zoo tshaj plaws, lub zog hloov hluav taws xob nws tus kheej tsis siv hluav taws xob.Kev tswj hluav taws xob tau ua tiav los ntawm kev kho lub sijhawm thaum lub transistor qhib thiab tawm.Ntawm qhov tsis sib xws, nyob rau hauv cov txheej txheem ntawm linear fais fab mov generating output voltage, lub transistor ua hauj lwm nyob rau hauv lub amplifying cheeb tsam, thiab nws kuj siv hluav taws xob zog.
Kev hloov pauv siab ntawm kev hloov hluav taws xob hloov pauv yog ib qho ntawm nws qhov zoo, thiab vim tias cov khoom siv hluav taws xob hloov pauv tau muaj qhov ua haujlwm siab, qhov me me thiab lub teeb yuag transformer tuaj yeem siv tau, yog li cov khoom siv hluav taws xob hloov pauv yuav me me thiab sib dua. tshaj qhov linear fais fab mov.
Yog tias qhov kev ua haujlwm siab, ntim thiab qhov hnyav ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb, kev hloov hluav taws xob hloov pauv tau zoo dua li cov khoom siv hluav taws xob linear.Txawm li cas los xij, cov khoom siv hluav taws xob hloov pauv yog qhov nyuaj dua, thiab cov transistors sab hauv tau nquag hloov.Yog tias qhov hloov pauv tam sim no tau ua tiav, lub suab nrov thiab electromagnetic cuam tshuam yuav raug tsim los cuam tshuam rau lwm yam khoom siv.Ntxiv mus, yog tias lub zog hloov hluav taws xob tsis muaj qhov tsim tshwj xeeb, lub zog ntawm lub zog hluav taws xob yuav tsis siab.
