Vim li cas ho tsis lub hwj chim amplifier siv switching fais fab mov
Piv nrog rau cov tsoos linear tswj fais fab mov, kaw lub hwj chim mov muaj ntau yam zoo, xws li kev hloov siab los ntseeg siab, high voltage thiab load stability, me me, lub teeb yuag, thiab lwm yam, uas tuaj yeem pom tseeb los ntawm kev sib piv ntawm cov khoom teev. nyob rau hauv lub rooj sib tham. Tab sis nyob rau hauv high-end suab hwj chim amplifier, txawm nws yog domestic los yog txawv teb chaws, yog vim li cas tsis siv switching fais fab mov? Kab lus no yuav tham txog tus sau lub tswv yim ntawm qhov teeb meem no thiab sib tham nrog koj. Thaum xyoo 1980s, qee lub tuam txhab txawv teb chaws kuj tau siv cov khoom siv hluav taws xob hloov pauv hauv lub hwj chim amplifiers, tab sis lawv txhua tus tau tso ib qho tom qab. Nws tau hais tias nws yog qhov nyuaj los daws qhov cuam tshuam ntawm electromagnetic cuam tshuam ntawm kev hloov hluav taws xob, thiab qhov loj ripple yog ib qho yooj yim los ua teeb meem xws li suab dyeing. Nyob rau hauv lub hwj chim amplifier, peb cia siab tias lub hwj chim mov ntawm lub amplifier yog ib tug tas mus li voltage qhov chaw (qhov no yog ib qho ntawm cov laj thawj vim li cas ib co neeg nyiam siv roj teeb rau lub hwj chim amplifier), kom nws tsis yooj yim los tsim clipping distortion. thaum soj ntsuam nrog loj dynamic signals. Ntawm chav kawm, nws tsis yog yooj yim los ua kom lub hwj chim mov ib qho kwv yees qhov voltage qhov chaw nyob rau hauv tiag tiag ntau lawm. Txij li thaum cov lus teb dynamic ntawm linear tswj fais fab mov yog sai dua li ntawm lub zog hloov hluav taws xob, thiab cov ripple generated yog me dua li ntawm lub zog hloov hluav taws xob, los ntawm ob qho no, cov kab hluav taws xob tswj hluav taws xob zoo dua li lub zog hloov hluav taws xob. muab. Tsis tas li ntawd, qhov cuam tshuam ntawm electromagnetic cuam tshuam ntawm kev hloov hluav taws xob muaj ntau dua li ntawm cov kab hluav taws xob tswj hluav taws xob, uas yuav ua rau lub suab tsis zoo thiab txo cov teeb liab-rau- suab nrov piv. Los ntawm qhov no, nws tsis zoo li siv cov khoom siv hluav taws xob linear tswj. Ua ntej txheeb xyuas cov khoom siv hluav taws xob hloov hluav taws xob uas ua rau muaj kev cuam tshuam ntawm electromagnetic, cia peb nkag siab qee cov ntsiab lus ntawm kev hloov hluav taws xob thiab cov khoom siv hluav taws xob tawm.
Hloov lub hwj chim amplifier rov pib dua
Lub zog hluav taws xob tawg. Lub hwj chim mov tsis ruaj khov.
Qhov thib ob yog xyuas ntawm DCDC fais fab kev tswj xyuas sab. Txawm li cas los xij, yeej tsis muaj nqi kho.
Lub hwj chim amplifier siv lub nplhaib nyuj thiab lub zog hloov hluav taws xob, uas muaj qhov yuam kev tsawg dua
Lub hwj chim zaus transformer (xws li lub nplhaib nyuj) muaj cov qauv yooj yim thiab ib qho yooj yim Circuit Court. Piv nrog rau lub zog hloov hluav taws xob nrog lub voj voog nyuaj, tus nqi tsis ua haujlwm yuav tsum qis dua. Qhov tsis ua hauj lwm ntawm qhov zoo hloov hluav taws xob kuj tseem tsawg heev, uas tsuas yog hais lus xwb.
