Cov lus ceeb toom ntawm kev siv lub suab nrov

1. Yuav kom ntseeg tau tias nws siv nyob rau hauv ib qho kev nyab xeeb voltage, nws yog qhov zoo tshaj plaws los siv 220V AC tswj fais fab mov los yog DC high-voltage regulated module.
2. Qhov yuam kev ntawm V + thiab V- yuav tsum tsis txhob siab tshaj 1V, thiab cov khoom siv hluav taws xob zoo thiab qhov tsis zoo thiab hauv av yuav tsum tau ua kom ruaj khov. Tsuas yog tig lub hwj chim tom qab welding tiav thiab paub tseeb tias muaj tseeb.
3. Nyob rau hauv thawj theem tom qab lub hwj chim amplifier IC yog powered ntawm ib txwm, nws stability yog tsis zoo tshaj ntawm discrete tivthaiv amplifiers. Yog li ntawd, nws yuav tsum tau "hlawv" los yog ua si ntawm lub ntim tsawg kawg yog 10 feeb ua ntej nws tuaj yeem ruaj khov thiab ua haujlwm tau zoo heev.
4. Thaum ua lub hwj chim amplifier, lub grounding yuav tsum nruj me ntsis tswj. Nws yog qhov zoo dua los siv ntau cov hlua ntawm cov tooj liab tuab raws li cov xaim hauv av. Koj tuaj yeem siv ob lub choj rectifier nrog cov cuab yeej siv hauv av kom ua kom nws cov teeb liab-rau-suab nrov piv.
5. Yog tias daim phiaj hluav taws xob hauv cheeb tsam muaj kuab paug loj thiab cov kab hluav taws xob qis hluav taws xob txuas nrog cov khoom siv hluav taws xob xws li vuam tshuab thiab silicon rectifiers, lub tshuab lim hluav taws xob tuaj yeem siv tau. Yog tias tsis tuaj yeem tshem tawm cov pa phem, lub tshuab hluav taws xob cais tawm tuaj yeem siv tau, tab sis yuav tsum muaj lub zog txaus.
6. Ua tib zoo mloog rau qhov kev txiav txim hloov ntawm cov khoom siv suab. Rau cov amplifiers ua nrog Hi-Fi amplifier ICs, nco ntsoov tig lawv kawg thiab kaw lawv ua ntej.
7. Ua ntej yuav txhim kho lub hwj chim amplifier IC tshiab rau hauv lub computer, nws yog qhov zoo tshaj plaws los siv lub qhov (socket), tsis txhob solder, thiab ruaj ntseg lub dab dej kub. Yog tias nws tsim hluav taws xob hnyav tom qab lub hwj chim qhib thiab tawm DC, tshem nws thiab xa rov qab mus rau chav xa ntawv.
8. Txhawm rau tiv thaiv lub amplifier IC los ntawm kev tso tawm DC uas tuaj yeem ua rau cov neeg hais lus tsis zoo, nco ntsoov nruab ib tus neeg hais lus tiv thaiv.
9. Cov khoom siv hauv lub cev yuav tsum tau ua kom zoo. Vim yog qhov asymmetric peb-theem load ntawm cov kab hluav taws xob qis qis, cov kab nruab nrab yuav muaj zog, thiab tom qab tau txuas nrog hauv av, lub peev xwm yog xoom, uas yog qhov zoo heev rau kev txhim kho cov teeb liab-rau-suab nrov piv. Txoj kev yog: siv lub ∮10mm ntev 1.5m round steel, welded nrog 2.5mm2 multi-strand tooj liab hlau (tsis txhob rivet los yog qhwv nws), thiab muab tso rau hauv lub sab nraum zoov ntub av.
