Nws siv sijhawm ntev heev los them lub roj teeb tsheb los ntawm DC qhov siv lub thawv them nyiaj. Yog tias koj hloov kho lub charger Circuit, koj tuaj yeem nce lub roj teeb ntxiv, tom qab ntawd lub roj teeb yuav them sai dua.
Cov Lus Qhia
Kauj ruam 1
Ua ib qho cia hauv inductor L1, xaiv hloov mus rau transistor thiab tso zis diode. Siv cov tub ntxhais uas tuav daim hlau loj thiab cov pas nrig sab nraud ntawm lub puab tsaig uas yog qhov sib nqus. Qhwv cov txheej txheem winding nrog PEV-2 xaim (1.5 hli) lossis ob lub PEV-2 xaim (1.0 hli) thiaj li txhawm rau sau lub qhov rais ntawm qhov sib nqus.
Kauj ruam 2
Siv lub hwj chim loj N-channel transistor IRFP264 rau qhov tseem ceeb transistor. Ib qho txuas ntxiv ntawm qhov xav tau rau nws, uas yuav ua kom muaj qhov sib txawv ntawm lub rooj vag qhov hluav taws xob ntawm 15 V (txheeb ze rau cov khoom, uas txuas nrog lub hauv paug txhawm). P-channel fais fab teb-nyhuv transistors tau yooj yim dua rau kev txuas rau hauv Circuit Court, txawm li cas los xij, kev hloov kho muaj tsawg heev, thiab lawv nyuaj nrhiav ntawm muag.
Kauj ruam 3
Hloov lwm txoj kev, siv n-p-n BUX 20 fais fab tuag transistor los ua lub zog tseem ceeb transistor Nws tau tsim tshwj xeeb rau lub hom phiaj no thiab muab hluav taws xob hloov mus txog 50A. Txawm li cas los xij, nws muaj qhov tsis zoo - qhov nce siab.
Kauj ruam 4
Nruab cov transistors, tso zis diodes thiab diode choj ntawm lub tshuab pa hluav taws xob nrog thaj tsam ntawm tsawg kawg 200-300 cm2 los ntawm mica gaskets. Koj tuaj yeem muab lawv txuas rau hauv cov hlau hauv qab ntawm cov khoom siv.
Kauj ruam 5
Ua kom haum tus schema. Txhawm rau kom ua kom zoo dua nrog lub charger tau teeb tsa, txuas lub nra thiab teeb lub siab tshaj plaws ua haujlwm tam sim no. Txuas lub ammeter rau qhov qhib Circuit Court ntawm emitter ntawm qhov tseem ceeb transistor, tom qab ntawd hloov lub cim hloov ntawm lub DA2 microcircuit kom txog rau thaum tsawg kawg tam sim no tau, xaiv lub resistor R9 thiab lub capacitor C6.
