Achitaurazve simba nerubatsiro nemaoko avo: zviri ungano uye kuchinja

Unorema kubva zvemagetsi vanoda musimba Kusasvika DC voltage 12 volts. Achitaurazve Power Supplies nemaoko enyu dzichidzidzisa Chip pamwe runodiwa parameters. Selection voitakura paredhiyo ouinjiniya pamatafura. Ichitenderera pasi transformer yakabereka pamusoro munhu ferrite mhete zvinhu mugiredhi - M200MN.

mukugadzira transformer

The chikuru ichitenderera ine imwe insulated waya MGTF 0,7 kubva yechipiri waya PEV-1 iyo yave wakapetwa kaviri. Pakati pavo vanofanira kuva insulating rukoko yakaitwa pamusoro PTFE tepi. The yechipiri ichitenderera pakati chikamu ane mamwe bazi kuti simba utariri chip. waya kunze dzakavharika aine miviri paiva Teflon tepi.

Achitaurazve simba nerubatsiro nemaoko avo pachavo vari akatasva rakadhindwa redunhu bhodhi rakagadzirwa Washington City Offices-mativi. kwakadaro Michina zvinogadzirwa kugadzirwa chinorondedzerwa zvizere mabhuku uye chisingakwanisi kutsanangurwa munyaya ino. Edza kudzidza nzira pcb zvakagadzirirwa pachishandiswa chinokosha Zano mudziyo. For transistors zvinodiwa radiators tinoitirwa ane aruminiyamu ndiro.

zvaida redhiyo

Somunhu chiyamuro kachidza zvakanyanya kushandisa huripo inductors, akaisa kazhinji nesimba rinopiwa yakadaro kana munhu kombiyuta anoratidza. The capacitor rinowanikwa kubva capacitance uye nesimba reshiyo mumwe munhu. The rectifier yakaitwa pachishandiswa ari diode zambuko ane pasi uchishandisa maitikiro. Mudziyo kwakadaro kungaita simba kuitika anosvika 3 amperes kuti goho.

Anoshandiswa redhiyo nokuchinja simba wedzerai redunhu iyo refu aishanda uye ikadzivisa, muri transistor haizoshandisi. Selection transistors rinoitwa pasi yakatarwa parameters, tsime-nekusimba dzakatevedzana IRF 840, kana VT 1 uye VT3. Transistors kupa tembiricha zvakafanira vanofanira kupisa rinosakara kubvisa kupisa yemuraudzo.

Achitaurazve simba rinopiwa nemaoko kuenda goho chikamu wedunhu inopiwa kune throttles kwakavakirwa ferrite humburumbira vanenge 40 mm pakureba ane dhayamita 3 mm. Zvakasimba ichitenderera wakagadzirwa zvakafanana waya sezvo yechipiri ichitenderera pamusoro transformer. Kushandiswa dzimwe nzira kuti pakudzikamisa ari goho boka, asi vakaratidza kuvimbika matunhu. Search zvimwe zvisarudzo iyi yaizova kutambisa nguva.

Assembly uye kuchinja

Quality simba nerubatsiro nemaoko avo pachavo soldered pamusoro takagadzirira purangazve. Kana installation ndiyo pakuraramisa dzose chiedza kubva kumabasa uye kufefetedza. Mushure pokunamatidza inokurudzirwa kuongorora rakavimbika kugadzwa zvigadzirwa zvinoriumba uye kuonana pakati pavo uye conductive nzira. On yomukati penyika vakachenesa solder nekubudisa residues aigona kutungamirira redunhu.

Achitaurazve Power Supplies, vakaunganidza maoko ake uye akagadzirira vomurova, Zvinokurudzirwa vapinze resistor razvino vakaomerwa panguva yokuedzwa. Izvi zvinogona kushandiswa incandescent rambi simba 60 W, ayo duku chinja bude nechiidzo peungano zvakakodzera.
