Ukutshintshela umbane ngezandla zabo: iimpawu ibandla kunye hlengiso

Isambuku izixhobo zekhompyutha kufuneka kwi kombane kwi DC lombane volts 12. Ukutshintshela Power Supplies ngezandla zakho ngokuya nge chip kunye parameters ezifunekayo. Ukhetho ithwalwa kwiitafile yobunjineli kunomathotholo. Ezehlela transformer eveliswa kwi umsesane ferrite izinto kwibakala - M200MN.

transformer lemveliso

Primary oyinkampani siquka ngentambo MGTF igqunyiwe 0.7 of iingcingo eziziisekondari PEV-1 ethe isongiwe kabini. Phakathi kwabo kufuneka kukho umaleko ubushushu leyo yenziwe PTFE tape. Secondary osuka kwi indawo ephakathi une isebe eyongezelelweyo chip yolawulo amandla. iingcingo ngaphandle avalwa ngomaleko kabini lwe Teflon tape.

Ukutshintshela umbane ngezandla zabo ziyaxhonywa kwibhodi yesekethe eprintiweyo eyenziwe fiberglass-macala. ezinjalo technology imveliso iimveliso ichazwe ngokwenkcukacha kwi ncwadi kwaye ngaphaya kwemida yeli nqaku. Umfanekiso iindlela ukuqhuba ngenxa PCB eyenzelwe ngokusekelwe scheme esisiseko ifowuni. Kuba transistors olufunekayo radiators ukuba ezenziwe kwisitovu aluminiyam.

radio efunwayo

Njengoko i ziliminxe igalelo ngendlela eyiyo ukusebenzisa inductors ezikhoyo, ibekwe ngokuqhelekileyo izinto mandla okanye nemiboniso ikhompyutha siqu. Le capacitor ebalwa capacitance kunye nomlinganiselo amandla enye ukuya kwenye. Le rectifier senziwa ngokususela bhulorho diode kunye njalo yokusebenza. Loo lesixhobo zinika amandla sangoku amperes ukuya ku-3 ukuya kwimveliso.

Used in radio isenza i wesiphaluka umbane elithe kudala okusebenzileyo lukhangelwe, zizinto itshintshela transistor. transistors Ukhetho lwenziwa kwi parameters amisiweyo, kuza kwenziwa kwakhona uthotho kakuhle nezingqinekayo IRF 840, okanye VT 1 VT3. Transistors ukubonelela ubushushu eziyimfuneko kufuneka olubi ubushushu ukususa surplus ubushushu.

Ukutshintshela izinto amandla ngezandla zabo ukuya kwimveliso isabelo yesekethe ezibonelelwe yi-throttles esekelwe cylinder ferrite ezimalunga nama-40 mm ubude kunye ububanzi of 3 mm. Tight oyinkampani yenziweyo locingo efanayo njengoko yesibini kwayijikeleza le transformer. Ukusetyenziswa kwezinye iindlela ekuzinziseni iqela imveliso, kodwa ukuthembeka engqiniweyo kwiisekethe. Khangela ezinye izigqibo kule meko iya kuba yinkcitha xesha.

Assembly and ukulungiswa

unikezelo mbane Umgangatho ngezandla zabo soldered ebhodini uzilungiselele. Xa ufakelo kuyimfuneko ukubonelela yesiqhelo Izibane zasemsebenzini kunye umoya. Emva kokuba ngelotha Kucetyiswa ukukhangela ukuthembeka ukufakelwa nezombane kunye nomfowunelwa phakathi kwabo kunye umendo conductive. Phezu engaphakathi iintsalela solder obhobhozayo zicocwe ezinokukhokelela kumphathi wesekethe.

Ukutshintshela Power Supplies, waqokelela izandla zakhe yaye ukulungele ukuqalisa, kucetyiswa ukuba ukulayisha resistor current umda ngexesha lovavanyo. Oku kusetyenziswa amandla eewathi isibane 60 W, switsha yayo eyeyomzuzwana bude sisalathisi kwindibano efanelekileyo.
