Kab lus no yog qhia tus tsav tsheb yooj yim. Txawm li cas los xij, qhov no yog qhov tseeb tsis yog qhov kev daws teeb meem pheej yig tshaj plaws rau lub cav tsav tsheb.

Khoom siv

Cheebtsam: Lub zog hloov hluav taws xob (TO3 lossis TO220 pob), 10-ohm resistor (5 Watt), lub hom phiaj dav dav, lub zog siv hluav taws xob (3 V lossis ob lub AA/AAA/C/D roj teeb), cua sov, 1-kohm kuj tsis paub meej resistor, laug.

Cov khoom siv xaiv tau: Hloov cov cua sov hloov.

Cov cuab yeej: Cov hlua hlau.

Yeem cov cuab yeej: Multimeter, pliers.

Kauj ruam 1: Tsim Circuit Court

Kuv siv cov qub PSpice simulation software los kos thiab sim ua lub voj voog kom txo sijhawm.

Tus nqi ntawm Circuit tuaj yeem raug txo los ntawm kev hloov Rb thiab Ro resistors nrog luv Circuit Court.

1N4001 diode xav tau los xyuas kom lub transistor saturation thiab yog li txo lub zog tawm mus. Qhov kev siv thib ob ntawm cov diode no yog kev tiv thaiv ntawm transistor collector-emitter thim rov qab tsis ncaj uas yuav ua rau lub transistor puas.

Qhov tsawg kawg nkaus voltage ntawm Rb/D/Ro node yuav tsis poob qis dua 0.9 V (Vd + VceSat = 0.7 V + 0.2 V = 0.9 V). Txawm li cas los xij, lub zog transistor puag yuav muaj kev tiv thaiv sab hauv siab li 100 ohms. Qhov kev tawm tsam no yog sib thooj rau transistor biasing current. Cov kev tawm dag zog ntau dua yuav txo qhov kev tawm tsam. Qhov no yog vim li cas koj yuav xav tau Rb resistor.

Koj tuaj yeem pom tias qhov siab tshaj plaws tam sim no tsawg heev. Qhov no vim tias 2N2222 transistor tsis yog lub zog siv hluav taws xob tab sis lub hom phiaj dav dav transistor. Cov tub ntxhais kawm ntawv kho software tsis muaj cov khoom siv fais fab transistor.

Kauj Ruam 3: Ua Circuit Court

Koj yuav tsum yuav lub tshuab hluav taws xob hluav taws xob yog tias koj tab tom tsim lub voj voog no. Koj tseem yuav xav tau lub rhaub dej kub (TO3 lossis TO220 cua sov).

Kev ntsuas cua sov ua kom sov tau qhia ntawm no:
