Lub zener voltage regulator muaj ib tug tam sim no limiting resistor R Stxuas nrog rau hauv series nrog cov input voltage VS nrog zener diode txuas nyob rau hauv parallel nrog lub load RL nyob rau hauv no reverse biased mob. Lub stabilized tso zis voltage yeej ib txwm xaiv kom zoo ib yam li breakdown voltage V Z ntawm lub diode.
Yuav ua li cas siv Zener diode los ua qhov ntsuas hluav taws xob?
Zener diodes tau dav siv los ua qhov kev siv hluav taws xob thiab raws li shunt regulators los tswj qhov voltage hla me me. Thaum txuas nrog rau qhov sib npaug nrog qhov sib txawv ntawm qhov sib txawv kom nws rov qab biased, Zener diode ua thaum qhov hluav taws xob mus txog lub diode qhov rov qab tawg voltage.
Vim li cas Zener diode yog voltage regulator?
Thaum Zener diode yog muab cov lus qhia rov qab tsis zoo, muaj qhov xau me me kom txog thaum nws ncav cuag qhov hluav taws xob tawg lossis qhov hluav taws xob tas li. Nyob rau lub sijhawm no, tam sim no pib ntws seamlessly yam tsis muaj kev hloov pauv hauv qhov hluav taws xob. Yog li ntawd, qhov hluav taws xob tas li pab Zener Diode li Voltage Regulator.
Vim li cas Zener diode siv los ua qhov ntsuas hluav taws xob hauv kev rov qab tsis zoo?
Nws ua raws li ib txwm diode hauv kev xa mus tsis ncaj ncees. Thaum lub Zener diode rov qab biased qhov sib txuas muaj peev xwm nce. Raws li qhov tawg voltage yog siab, qhov no yuav muab high voltage tuav lub peev xwm. Raws li qhov rov qab voltagence, qhov rov qab tam sim no nce siab ntawm ib qho hluav taws xob rov qab.
Puas yog Zener diode thim rov qab?
Zener diodes tsuas yog reverse-biased diodes uas tuaj yeem tiv taus kev ua haujlwm hauv kev tawg. Raws li qhov rov qab tsis zoo voltage nce, Zener diodes txuas ntxiv ua tus nqi tas li ntawm tam sim no (saturation tam sim no), kom txog rau thaum qee qhov hluav taws xob mus txog.
