Taw qhia:

Hnub no peb yuav tham txog yuav ua li cas koj thiaj ua tau qeeb qeeb Timer Circuit. txoj hauv kev ua haujlwm hauv Circuit yog tias ib zaug koj nias lub push_Button los ntawm qhov ntawd lub load uas txuas nrog lub Circuit Court yuav ua haujlwm. Thiab tom qab ib ntus, lub nra yuav tawm. qhov no feem ntau yog kev sib tham thaum lub sijhawm luv.

Lub Circuit Court Ua Haujlwm Li Cas?

Lub Sij Hawm Timer Circuit txuas nrog lub zog 12V. Thaum koj nias lub ncua sij hawm qeeb ces tam sim no ntws los ntawm Vcc mus rau GND los ntawm c1 Capacitor. Rau qhov no, Capacitor tsub. Tam sim no ib zaug peb tshem lub khawm tom qab ntawd lub Capacitor Tso Tawm los ntawm Mosfet's GATE Pin. Yog li rau qhov no, MOSFET dhau los ua tus coj.

Raws li qhov tshwm sim, Tam sim no ntws los ntawm DRAIN mus rau SOURCE Pin. Raws li qhov tshwm sim, Lub Load uas txuas nrog lub Circuit Court yuav dhau mus. Hauv peb qhov xwm txheej, peb tau Txuas Txuas 100w LED.

Yog tias koj pom lub voj voog ua tib zoo ces koj yuav pom tias peb tau txuas nrog 100K Resistor thaum uas tig mus nrog lub capacitor. Tus Resistor yog txhawm rau nce tus nqi tawm rau Capacitor. yog tias koj ua haujlwm tus nqi zoo dua tus tiv thaiv tus nqi tso tawm mus rau hauv qab no thiab yog tias koj siv tus nqi qis dua tus tiv thaiv ces tus tso tawm tus nqi hluav taws xob yuav nce siab dua rau ncua sijhawm.

Hauv qhov no Txoj Kev Ncua Sijhawm Timer Circuit Ua Haujlwm.

Yam twg koj yuav tsum paub txog ncua sijhawm ncua sijhawm Circuit?

Qhov no yog ib qho yooj yim Transistor Circuit nrog lwm cov khoom ntxiv. Ntawm no peb tab tom siv N-Channel txhim kho hom Mosfet. Raws li qhov tshwm sim, cov zis tam sim no nyob deb tshaj li niaj hnub NPN Transistor. koj yuav siv lwm N-Channel Mosfet raws li koj xav tau. IRFZ44n tej zaum yuav yog MOSFET ntau heev yog li, thaum lub sijhawm no, kuv tab tom siv IRFZ44N Mosfet. Ntawm no tus Resistor thiab yog li ntawd Capacitor txuas nrog hauv Parallel.

Tus Capacitor tsub los ntawm 12V Lub Hwj Huam thiab yog li ntawd tus Resistor tso lub capacitor tawm. yog tias koj ntiav tus nqi siab dua ntawm tus tiv thaiv ces tus capacitor yuav tso tawm qeeb. thiab yog tias koj ntiav tus nqi qis dua Resistor ces lub capacitor yuav tso tawm tsis muaj sijhawm thiab yog li ntawd Ncua Sijhawm Timer Circuit yuav tawm tsis muaj sijhawm.

Tsis txawv, nws tuaj yeem tshwm sim. Piv txwv tias koj tab tom xaiv tus nqi raug cuam tshuam resistor tom qab ntawd koj hloov pauv Capacitor. Yog tias koj ua haujlwm zoo dua tus nqi hluav taws xob nrog siv rau qhov sib npaug resistor ces tus capacitor yuav siv sijhawm ntau npaum li cas los tso tawm. Tam sim no peb txhua tus paub txoj cai rau Kev Ncua Sijhawm Timer Circuit tias yog peb siv tus nqi qis dua nrog cov khoom siv rau qhov sib npaug Resistor ces kev tso tawm yuav nrawm dua piv rau thawj zaug. Yog li kuv lub ntsiab lus yog tias Ncua Sijhawm Sijhawm Circuit Court feem ntau sib txawv nrog tus Resistor thiab yog li tus Capacitor Tus Nqi.

Koj tseem tuaj yeem txuas qhov txuas nrog ntu thauj khoom ntawm Mosfet. Tam sim no lub Circuit Court yog ncua ncua sijhawm timer relay Circuit. Koj yuav tsum tsis txhob xaiv tus nqi ntau dhau ntawm tus nqi qis dua lwm yam kev tso tawm tus nqi yuav nrawm dua.
