Daim ntawv thov Voltage ZENER DOPDE Thiab TVS DIODE

(1) Kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob: Lub tshuab hluav taws xob hluav taws xob tawg ntawm qhov tseeb qhov hluav taws xob, uas ua rau nws tsim nyog siv los ua qhov txwv lossis tiv thaiv kev tiv thaiv hluav taws xob, vim muaj ntau yam voltage regulator diodes tuaj yeem tau txais, ua rau nws tsim nyog rau daim ntawv thov no.

(2) Overvoltage tiv thaiv Circuit Court nyob rau hauv lub TV: EC yog lub ntsiab mov voltage ntawm lub TV. Thaum EC voltage siab dhau lawm, D1 yog conductive, thiab transistor BG yog conductive. Nws cov peev xwm sau tau yuav hloov pauv los ntawm qib siab qub (5V) mus rau qib qis, thiab TV yuav nkag mus rau lub xeev kev tiv thaiv kev tiv thaiv los ntawm kev tswj hwm ntawm cov kab hluav taws xob standby.
