High-power Darlington raj tshuaj xyuas

High-power Darlington tau ntxiv ib qho kev tiv thaiv Circuit Court uas muaj lub freewheeling diode thiab ib tug bleeder resistor nyob rau hauv lub hauv paus ntawm lub zoo tib yam Darlington raj. Kev ntsuas yuav tsum tau xyuam xim rau qhov cuam tshuam ntawm cov khoom no ntawm cov ntaub ntawv ntsuas.

Qhov kev tiv thaiv rau pem hauv ntej thiab rov qab qhov tseem ceeb ntawm Darlington tube collector hlws ris (nruab nrab ntawm lub collector c thiab puag b) yog ntsuas nrog ib tug multimeter R × 1 kΩ los yog R × 10 kΩ. Nyob rau hauv ib txwm lub sij hawm, tus nqi rau pem hauv ntej tsis kam (thaum lub hauv paus ntawm NPN raj txuas nrog cov hlau lead kuaj dub) yuav tsum me me, 1 txog 10 kΩ, thiab tus nqi rov qab yuav tsum nyob ze rau infinity. Yog tias qhov ntsuas qhov tseem ceeb ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom ntim khoom me me los yog tsis kawg, lub raj tau luv luv los yog qhib-circuit puas.

Siv cov ntaub ntawv multimeter R × 100 Ω los ntsuas qhov zoo thiab qhov tsis zoo ntawm cov emitter e thiab lub hauv paus b ntawm Darlington raj. Cov nqi ib txwm muaj ntau pua ohms mus rau ntau txhiab ohms. Cov ntaub ntawv tshwj xeeb yog raws li b thiab e. Qhov tsis kam ntawm ob lub resistors yog txawv. Piv txwv li, qhov zoo thiab thim rov qab qhov tseem ceeb ntawm lub zog siab Darlington raj b thiab e ncej ntawm BU932R thiab MJ10025 yog hais txog 600 Ω, yog ntsuas. Qhov tsis kam ntawm 0 lossis infinity qhia tias lub raj hauv kev sim puas lawm.

Qhov tseem ceeb rau pem hauv ntej thiab thim rov qab qhov tseem ceeb ntawm lub emitter e thiab lub collector c ntawm Darlington raj yog ntsuas nrog ib tug multimeter R xl kΩ los yog R × 10 kΩ. Nquag, tus nqi tiv thaiv rau pem hauv ntej (thaum ntsuas lub NPN raj, lub ntsuas dub yog txuas nrog lub emitter e, lub ntsuas liab txuas nrog lub collector c; thaum ntsuas lub raj PNP, lub ntsuas dub txuas nrog lub ntsuas c, Cov ntsuas liab txuas nrog lub emitter e) yuav tsum yog 5 ~ 15 kΩ (BU 932R yog 7 kΩ), tus nqi thim rov qab yuav tsum tsis kawg, txwv tsis pub c, e ncej (los yog diode) tawg lossis qhib kev puas tsuaj ntawm lub raj.
