Kodi kufufuza transistor

Mu dziko zamakono simungakhoze kuchita popanda transistors. Iwo anabwera zosiyanasiyana zamakono, angapezeke mu mafoni, mawailesi, makompyuta ndi magalimoto. Nthawi zina pali kufunika kwa yachinsinsi cha ntchito yawo, ndipo kenako zothandiza kudziwa mmene fufuzani transistor ndi kuti amafuna. Nkhani zili m'nkhani anafotokoza nkhani.

Transistors ndi mitundu

chipangizo Izi pazipangizo ponena kuti tiyambe electroschemes choyambirira chizindikiro. Chopangidwa kuchokera ku zipangizo michenga yopangira zida zamagetsi. Pali 2 mitundu ya transistors: kumunda ndi ochititsa kuti, si ankalamulira voteji ndipo panopa. Komanso, iwo akhoza kukhala wochepa thupi ndi amphamvu, otsika ndi pafupipafupi mkulu. Iwo amasiyana kukula ndi mamangidwe a nyumba.

Nthawi zambiri potchula transistors ochititsa kuti zikutanthauza mitundu yawo, ndi opangidwa ndi germanium kapena pakachitsulo. Iwo amatchedwa matenda a kusokonezeka chifukwa ntchito ndi ma elekitironi (mlandu zonyamulira) ndi mabowo. Limodzi mwa madera a transistor ili m'mphepete, otchedwa emitter, wapakatikati - m'munsi, ndi ena, komanso inali pa m'mphepete - wokhometsa. Popeza elekitirodi 3 amalenga pn kusintha 2: wokhometsa oyenerera pakati wokhometsa ndipo m'munsi, ndi emitter amene chikugwirizana pakati pa emitter ndi tsinde. The transistor kungakhale ya "pa" boma "kutali", ndi kusintha pakati pawo ikuchitika mwa chizindikiro magetsi.

Cholinga transistors - m'badwo, amveke ndi kutembenuka kwa oscillations magetsi. Koma, monga chipangizo aliyense luso, ndi transistor angalephere. Muyenera kudziwa mmene fufuzani transistor kuti chifukwa kuti chomveka. Pakuti multimeters cholinga.

Afufuze transistor Tester

Multimeter (Aka Tester) - chapadera kuphatikiza chida chimene kuchititsa ntchito magetsi. Chili ntchito zingapo: ngati osachepera Chili ammeter, voltmeter, ohmmeter. Pali onse analogi ndi zipangizo digito, kuwala, kunyamula ndiponso n'kupuma, chomwe chili kwambiri mwayi.

Meter - chipangizo kuti limatiuza mmene fufuzani transistor ndi bwino. Tester amalola ndi oyimba ndi kukana kuyeza dera otsika, Alamu zikumveka, kulira kapena kuwala.

Tisanaone njira, mmene fufuzani transistor Tester, ndikofunika kudziwa kuti zipangizo anawagawa mitundu 2 molingana ndi makonzedwe a zigawo ndi madutsidwe osiyana. Choncho pali semiconductors ndi madutsidwe zamagetsi (pnp), ndipo semiconductors tsa-mtundu (p-).

Kuyesa kulimbikira kusintha mwachindunji maziko a kugwirizanitsa "opanda" mita ndi emitter ndi wokhometsa nayenso kulumikiza "kuphatikiza". kusintha udindo wa "opanda" ndi "kuphatikiza" mu miyeso n'zosiyana kukana. Kuti kuyeza kukana kusintha pnp Bwerezaninso zomwezi, koma preliminarily kusintha polarity. Pa cheke kusintha kwa m'munsi kwa emitter ndi wokhometsa ayenera prozvanivatsya mbali 1 yekha.

Popeza multimeter kuti aletse transistor kungakhale, koma zilibe kupereka chitsimikizo mtheradi wa Kutukula chipangizo, pakuti wamkulu ndithu ayenera kukhala review ake mu mode yogwira. Pankhaniyi, ndipo zotsatira zake zidzakhala odalirika kwambiri.

Ndipo komabe: bwanji kuti aletse transistor ndi kukhulupirira mu zotsatira? Mu zipangizo ochititsa kuti kwa mayiko, mungapeze kwa Anzawo diode aliyense kusintha ake, pambuyo afufuze Kutukula awo. Pali transistors amphamvu omwe pakati pa emitter ndi wokhometsa wa damper thupi diode, ndi pakati pa tsinde ndi emitter - ndi resistor zozitetezera. Pamene mita pa polarity aliyense transistor uyu adzakhala kulimbikira ohms pa makumi kwa makumi asanu, ndipo prozvanivatsya pakati emitter ndi wokhometsa zidzachitika monga diode a. Izi zimasonyeza kuti Kutukula zigawo.
