Nyob zoo txhua tus ….

Txhua tus tau hnov txog SMPS. Tab sis pes tsawg tus paub txog nws ua haujlwm ??

SMPS yog qhov xav tsis thoob rau kuv. Yog li kuv tab tom tshawb nrhiav ntau ntxiv txog nws. Tam sim no kuv paub me ntsis txog nws. Ntawm no kuv tab tom sim qhia me me yooj yim SMPS Circuit. Ntawm no nws tau siv rau kev them nyiaj ntawm ob lub Ni-MH hlwb. Nws yog tib lub transistor SMPS. Lub plawv ntawm Circuit Court yog transistor. Hauv qhov haujlwm no, transistor tsis ua haujlwm ntau zaus. Tab sis thaum kawg qhov kev hloov kho ua haujlwm zoo. Yog li saib xyuas. Lub hauv paus tseem ceeb ua haujlwm ntawm 230V AC. Nws yog qhov txaus ntshai rau peb. Yog li coj koj tus kheej txoj kev pheej hmoo.

Cia peb pib qhov haujlwm. !!!!

Kauj Ruam 1: Kev Ntseeg & Ua Haujlwm

Txoj kev xav

SMPS yog dab tsi ??? Txhua leej txhua tus tuaj yeem teb rau lo lus nug no. Vim tias nws tsis muaj dab tsi tab sis nws tsuas yog tsim hluav taws xob qis DC los ntawm qhov hluav taws xob siab AC.

Tab sis muaj lwm qhov teeb meem. Peb paub txog lub tshuab hluav taws xob DC hloov pauv siv lub npe FULL BRIDGE RECTIFIER nto moo thiab ntau zaus peb tau siv nws. Nws tsim cov hluav taws xob qis DC. Yog li vim li cas peb thiaj xav tau SMPS. Kuv tau kawm ntau ntxiv los daws cov lus nug no hauv kuv thaum yau. Tom qab ntawd kuv pom tias lub tshuab hloov pauv yog cov cuab yeej tawm kab yog li nws qhov hluav taws xob tso tawm tau hloov pauv nrog kev hloov pauv hluav taws xob. Tab sis SMPS tsis yog kab tawm, yog li nws qhov hluav taws xob tso tawm tas li tsis hais txog qhov ntsuas hluav taws xob. Nws yog nws lub ntsiab kom zoo dua. Lwm qhov kev sib piv muab rau hauv qab no.

Transformer fais fab mov

• Cov zis hluav taws xob sib txawv nrog cov hloov hluav taws xob hloov pauv
• Qhov hnyav thiab loj
• Cov hluav taws xob tsis ruaj khov
• Tsis nyuaj
• Lwm yam

SMPS

• Cov zis hluav taws xob tas li tas li
• Qhov hnyav thiab qhov loj me
• Ruaj tso zis voltage
• Siab heev
• Lwm yam

Ua hauj lwm

Hauv SMPS kuj tseem siv lub tshuab hloov pauv. Tab sis nws yog qhov ntau zaus ib qho vim tias nyob hauv qhov ntau zaus tus naj npawb ntawm cov hloov pauv txo kom qhov loj ntawm cov hloov pauv hloov zuj zus. Yog li txhawm rau tsim cov zaus peb siv transistor thiab winding hauv kev hloov pauv rau kev tawm tswv yim rau oscillator. Tom qab ntawd qhov hluav taws xob ntawm thawj qhov sib txawv siv PWM thev naus laus zis. Ntawd yog, tswj cov oscillator lub luag haujlwm hloov pauv qhov nruab nrab qhov hluav taws xob. Los ntawm qhov no peb tau txais qhov hluav taws xob ruaj khov ntawm cov zis. SMPS block daim duab sawv cev muab rau hauv daim duab.

Cov ncauj lus kom ntxaws muab rau ntawm kuv qhov blog. Thov mus ntsib nws.

Kauj Ruam 2: Tsim Circuit Court

Cov kauj ruam tsim yog muab hauv qab no

• Tsim lub rectifier los hloov cov khoom siv hluav taws xob AC rau DC rau kev ua haujlwm ntawm transistor.
• Xaiv lub transistor uas tiv taus qhov siab thiab qhov zaus thiab qhov xav tau tam sim no.
• Tsim ib qho kev sib txuas ntawm transistor.
• Tsim kev tawm tswv yim network rau transistor kom ua tiav cov oscillator
• Tsim lub rectifier thiab lim ntawm cov zis
• Tsim qhov ntsuas hluav taws xob ntsuas hluav taws xob rau qhia pom lub roj teeb them tas

Cov ncauj lus kom ntxaws tsim thiab piav qhia Circuit tau muab rau hauv kuv qhov blog. Thov mus ntsib nws.

SMPS hloov pauv (1) - los ntawm lub xov tooj txawb qub

Txhua yam khoom tau txais los ntawm PCBs qub, Nws yog qhov zoo, Vim tias nws yog txheej txheem rov ua dua tshiab. Yog li koj sim txhua qhov khoom siv los ntawm PCBs qub. OK.

Cov ncauj lus kom ntxaws tsim thiab piav qhia Circuit tau muab rau hauv kuv qhov blog. Thov mus saib nws.

Kauj Ruam 3: Ua Pcb

Ntawm no kuv tau teeb tsa kev teeb tsa nrog tsis siv software. Kuv kos lub pcb tsim hauv daim ntawv dawb. Nws ua tiav los ntawm ob peb zaug ntawm kev kos thiab rov ua cov txheej txheem txhawm rau nrhiav qhov chaw zoo ntawm txhua feem. Tom qab ua tiav qhov no kuv theej nws mus rau qhov tsim nyog tsim nyog PCB siv tus cim ruaj khov. Tom qab ntawd tom qab ziab cov kua mem tas lawm, kuv rov ua cov txheej txheem rov ua dua ob peb zaug kom ntseeg tau tias qhov tuab zoo ntawm daim npog rau kev kos. Txwv tsis pub tsis tau txais PCB zoo.

Kauj Ruam 4: Drilling Qhov

Rau lub hom phiaj drilling Kuv siv lub tshuab xuas tes ua nrog tsawg dua 0.5 hli laum ntsis. Uas qhia hauv daim duab. Ua tib zoo ua txhua qhov nrog ua kom puas rau PCB. Tom qab ntawv rov teeb tsa ib zaug kom ntseeg tau tias qhov tuab ntawm daim npog. Tom qab txoj haujlwm no ntxuav PCB kom tshem plua plav.

Kauj ruam 5: Etching

Txhawm rau kos, coj FeCl3 (ferric chloride) hmoov rau hauv lub thawv yas. Tom qab ntawd ntxiv qee cov dej rau nws. Tam sim no nws zoo li xim liab. Tom qab ntawd muab cov PCB tso rau hauv nws los ntawm kev hnav cov nyom hauv koj txhais tes. Tom qab ntawd tos 20 feeb kom yaj cov tooj liab uas tsis xav tau. Yog tias tooj liab tsis yaj tag tos rau qhov ua kom yaj tag. Tom qab tag nrho cov txheej txheem zom cov PCB los ntawm kev daws thiab ntxuav nws los ntawm kev siv cov dej huv thiab tshem cov kua nplaum. Rau tag nrho cov txheej txheem hnav hnab looj tes.

Kauj ruam 6: Soldering

Thov ib txheej tuab tuab me me rau tag nrho cov cim PCB. Nws txo cov tooj liab txhuam nrog cua. Nws yuav nce PCB lub neej. Rau kev tshaj lij PCB's siv lub qhov ncauj qhov ncauj. Tom qab lub qhov ncauj qhov ntswg no, muab cov khoom sib dhos tso rau hauv nws txoj haujlwm. Qhov chaw hloov pauv hauv sab laug ntawm PCB kom txuag tau qhov chaw PCB. Ua ntej muab cov khoom me me thiab tom qab ntawd loj dua. Tom qab qhov no, txiav cov khoom tsis xav tau ntawm cov khoom siv thiab ntxuav PCB siv PCB nqus tsev ntxhua khaub ncaws (IPA daws).

Kauj Ruam 7: Xeem

• Thawj zaug ua qhov ntsuas pom rau ib qho luv Circuit Court lossis txiav hauv PCB khiav.
• Tom qab ntawv hla cov PCB thiab cov khoom siv nrog daim duab hluav taws xob.
• Siv ntau lub ntsuas ntsuas ib qho luv luv tam sim no nyob rau sab nkag.
• Tom qab ua tiav ntawm txhua qhov kev ntsuas txuas lub Circuit Court mus rau 230V AC.
• Txheeb xyuas qhov ntsuas hluav taws xob tso tawm thiab teeb tsa ua ntej rau txoj haujlwm uas qhov kev them nqi hluav taws xob tag nrho (2.4v) ua tiav los ntawm kev siv ntau lub ntsuas.

Thaum kawg Peb Ua Peb Lub Circuit Court. Hlo ……

Kauj Ruam 8: Muab lub Circuit Court tso rau hauv lub Cabin

Ntawm no kuv siv lub npog ntawm lub xov tooj txawb qub them. Lub thawv roj teeb qub tau teeb rau hauv lub roj teeb kom tso lub roj teeb. Cov duab tiav yog muab rau saum toj no. Laum qhov kom tso cov coj ntawm sab saum toj. Cov xov hluav taws xob tau txuas nrog lub pin nkag ntawm lub charger.

Peb cov nqi roj teeb SMPS yooj yim tau ua tiav. Nws ua haujlwm zoo heev.

Cov lus piav qhia luv hauv Circuit muab rau hauv kuv qhov blog. Qhov txuas hauv qab no. Thov mus ntsib nws.
