Nyob zoo

Hnub no, Vajtswv txaus siab, Kuv yuav qhia ib daim vis dis aus uas piav qhia qhov tseem ceeb los tswj kev nrawm ntawm kev sib hloov ntawm lub khoos phis tawj computer, lossis cov kiv cua uas khiav ntawm qhov txuas txuas tam sim no, Los ntawm kev siv LM7812 linear voltage regulator, Nrog BD139 transistor uas ua haujlwm zoo li tus yuam sij.

Tom qab kev qhia, daim duab thiab teeb tsa cov lus nug thiab kev piav qhia ntawm kev sib txuas tau tshwm sim, tom qab uas daim duab tau nthuav tawm hauv qhov ua piv txwv thiab ntu kawg uas qhov kev ntsuas tau sim hauv Circuit.

Ntawm no kuv yuav qhia koj cov khoom ntawm txoj haujlwm:-

  1. Transformer 12V, 1A hloov pauv
  2. Tawm qhov ntsuas hluav taws xob LM7812
  3. Choj rectifier
  4. Capacitor 1000uF, 35V
  5. 0.1Uf ceramic capacitor
  6. transistor BD139
  7. NTC 10K tsis zoo coefficient thermal sensor
  8. Qhov tsis kam ntawm qhov sib txawv Tremer yog 5Kohms
  9. Computer kiv cua

Kauj Ruam 3: Tshooj Cai

Kuv xav sim qhov kev ua haujlwm ntawm lub cuab yeej ntawm lub rooj noj mov.

los ntawm kev hloov tus nqi ntawm qhov sib txawv resister kuv tuaj yeem hloov kho qhov tseem ceeb ntawm kiv cua pib.

txog tam sim no cov ntaub ntawv ntau ntxiv txog kev ua ntu zus koj tuaj yeem saib cov vis dis aus.
