The simba zvitengeswa (12 V) nemaoko ake pachake. Simba zvitengeswa redunhu chikwata 12 Volt

Power zvitengeswa 12 volt simba nerubatsiro kuchaita kuti chero imba mudziyo, kusanganisira kunyange Laptop. Tapota ona kuti Laptop iri chiyamuro voltage kusvika 19 volts. Asi zvichaita kushanda chete yakanaka kana muchichengeta nekushambidza 12. Zvisinei, kufadza kwazvino 10 Amps. Chete kuti tsika dzakadaro kuparadzwa kunobva chaizvo kashoma, avhareji iri kuchengetwa 2-4 amps. Chimwe chinhu chokufunga nezvacho - ane mwero yokutsiva simba wedzerai kushandisa musha-yakaitwa pakuvara bhatiri hakushandi. Kunyange zvakadaro, simba wedzerai 12 volts ndiyo yakanaka, kunyange zano rakadaro.

Power zvitengeswa parameters

Anokosha parameters chero simba nerubatsiro - zviri goho voltage uye iyezvino. tsika dzavo kuvimba mumwe - kubva waya rinoshandiswa yechipiri ichitenderera pamusoro transformer. Kuti mashoko sei kuti kuitisa sarudzo nayo ichakurukurwa gare gare. Nokuti ini, iwe une kufanosarudza chinangwa aunoda kushandisa simba nerubatsiro 12 volts. Kana uchida simba neyamapani simba midziyo - navigators, LEDs, nezvimwewo, zvakakwana goho 2-3 amps. Uye ichi chichava yakawanda.

Asi kana aunoda kushandisa kuti vaite zviito zvikuru - somuenzaniso, kuti undoraira bhatiri mumotokari, unofanira anongoerekana 6-8 amps. Ndinorova ano vanofanira kuva kagumi isingasviki vachikwanisa of bhatiri - zvinodiwa izvi zvinofanira kufunga. Kana pane vanoda kubatanidza mano, pomugove voltage inova yakasiyana 12 Volt, zvine musoro kuisa kuchigadzirisa.

Sei kusarudza transformer

The chinhu chokutanga - a voltage convert. Transformer kunobatsira zvokuchinja AC voltage kuti 220 volts kune imwe amplitude, asi kukosha huduku zvikuru. Pamwero muduku zvikuru, unofanira kukosha duku. Nokuti mukuru-simba vezvikwata sezvikonzero tinogona kutora transformer TS-270. It aine simba, kunyange pane 4 windings, izvo nyaya yokuti 6.3 neimwe volts. Vakashandisa Vacuum sepombi kuti kudziyisa zvokudya. Nyore mariri, unogona kuita simba nerubatsiro 12 Volt 12 BSN, izvo zvinogona kunyange undoraira bhatiri mumotokari.

Asi kana iwe usiri kugutsikana zvakakwana kwayo ichitenderera, zvinokwanisika kubvisa zvose yechipiri, kusiya chete nemambure. Uye kubata ichitenderera waya. Dambudziko iri sei kuverenga nhamba inodiwa muchichinjana. Nokuti ichi tinogona kushandisa nyore kukarukureta zano - nhamba windings unotora yechipiri ichitenderera unobereka 6.3 volts. Zvino chete kugovera 6.3 nenhamba muchichinjana. Uye iwe uende voltage ukoshi, izvo zvinogona kubviswa pamwe chete loop kuti waya. Zvazvinosarira chete kuverenga zvakadini unofanira mhepo yacho Coils kuti nzira yokubudisa 12.5-13 volts. Zvaiva nani kana goho achava 1-2 volts kupfuura zvaaida voltage.

Production rectifier

Chii chinonzi rectifier, uye chii nokuda? mudziyo uyu inobva semiconductor diodes, ndiro transducer. With payo, ive rakatumbuka ano iri vatendeukira DC. Nokuti Kuongorora rectifier pechikuva kushandisa oscilloscope zvakajeka. Kana ukaona pamberi diodes sinusoid pashure pavo vachava zvachose sandara mutsetse. Asi maduku zvipenga Sine Wave unongoramba ari. Rasa navo pashure.

By pakusarudza diodes vanofanira kubatwa chakazara kukomba. Kana simba wedzerai 12 volts rinoshandiswa senzira bhatiri zaryadchika, tinofanira kushandisa zvinhu vane neizvi ano mutengo kusvika 10 amperes. Kana isu kuda kuita shoma-voltage simba nerubatsiro vatengi, Zvaringana achavakira zambuko. Pano inokosha chemabhazi. Zvatinofarira anopiwa kuti rectifier redunhu, yakaunganidzwa nokuda mhando Bridge - diodes mana. Kana tikashandisa chete semiconductor (hafu-wave redunhu), simba wedzerai kunyatsoshanda ipfupi ne vanenge hafu.

firita module gungano

Zvino, kana goho ane DC voltage, zvakafanira kuti ari chinogumbura Mufananidzo simba 12 volts akanga zvishoma hwakavandudzika. Nokuti chinangwa ichi zvakakosha kushandisa filters. Kuti simba musha midziyo yemagetsi kushandisa LC-chain zvakakwana. On zvakakodzera kuudza zvizere. To zvakanaka goho pamusoro rectifier chikuva kwakabatana inductance - throttle. The kuitika unofanira napo, ichi ndicho chokutanga filtration rwakazara. Next anouya wechipiri - ane electrolytic capacitor makuru vachikwanisa (zviuru zvakawanda microfarads).

Mushure reactor zvakabatana zvakanaka electrolytic capacitor. goho rayo wechipiri zvakabatana pasi (kubvisa). Musimboti wacho electrolytic capacitor ndechokuti kunoita kuti kubvisa zvose AC chikamu. Yeuka, panguva goho iri rectifier vakanga zvidimbu chiduku Sine Wave? Pano, zvinokosha kuti kuchiparadza, kana simba nerubatsiro 12 Volt 12 BSN achaita kupindira namano chokuita nayo. Somuenzaniso, redhiyo kana redhiyo achava emit zvakasimba ruzha.

Kudzikamiswa of goho voltage

Nokuti Kudzikamiswa pamusoro goho voltage anogona chete kushandisa imwe semiconductor maatomu akafanana. Izvi zvinogona kuva diode ane nokushanda voltage 12 volts, uye zvakawanda zvemazuva ano uye yakagozha gungano mhando LM317, LM7812. Recent akagadzirirwa voltage Kudzikamiswa pa 12 volts. Saka, kunyange pasi ezvinhu kuti goho rectifier Danho 15 volts pashure Kudzikamiswa achava chete 12. Mamwe achipinda kupisa. Izvi zvinoreva kuti zvakakosha kuisa stabilizer pamusoro redhiyeta.

voltage chengetedzo 0-12 V

Nokuti chikuru pakawanda ari mudziyo vanofanira kushandisa dunhu nyore kuti kunogona kuvakwa mumaminitsi mashoma. Izvi zvinogona chinozoiswa achishandisa yambotaurwa LM317 gungano. musiyano kubva redunhu nokuchinja muoti Kudzikamiswa chete diki. The yokumbozorora waya, izvo anoenda kubvisa, kushandisa shanduka resistor 5 ohms. Pakati nzira yokubudisa gungano uye shanduka resistor zvaisanganisira nemishonga vanenge 220 ohms. A pakati chiyamuro uye goho kuti stabilizer harungashandurwi voltage kudzivirira - the semiconductor diode. Saka, simba nerubatsiro 12 volts, maoko yakaunganidzwa, mudzoke kunyika multifunction mudziyo. Zvino inoramba chete kuti gungano racho uye calibration yacho pakafunuka. Uye iwe unogona kuita goho kuisa electronic voltmeter, umo uye murinde ano voltage.
