Kev tiv thaiv rov qab polarity yog ib qho hluav taws xob sab hauv uas ua kom lub cuab yeej tsis puas yog tias lub hwj huam mov polarity thim rov qab. Lub rov qab polarity tiv thaiv Circuit Court txiav tawm lub hwj chim mus rau lub rhiab hluav taws xob circuits nyob rau hauv lub transmitter los yog transducer.
Vim li cas thiaj li muaj kev tiv thaiv rov qab polarity?
Yuav muaj tshwm sim ntawm kev txuas cov xov hlau mus rau qhov tsis ncaj ncees lawm ntawm lub roj teeb. Qhov kev ua yuam kev no tuaj yeem ua rau tuag taus thiab ua rau cov khoom puas hauv cov khoom siv hluav taws xob. Txhawm rau kom tsis txhob muaj kev puas tsuaj zoo li no, yuav tsum muaj kev tiv thaiv rov qab polarity. Schottky diodes yuav muaj lub zog poob siab.
Koj tiv thaiv qhov hluav taws xob rov qab li cas?
Qhov yooj yim tshaj plaws tiv thaiv kev tiv thaiv rov qab roj teeb yog a diode hauv koob nrog lub roj teeb, raws li pom hauv daim duab 1. Hauv daim duab 1, lub diode ua rau pem hauv ntej thiab lub nra hnyav. kev khiav hauj lwm tam sim no ntws los ntawm lub diode. Thaum lub roj teeb tau teeb tsa rov qab, lub diode thim rov qab-biases thiab tsis muaj qhov ntws tam sim no.
Pob fuses tiv thaiv rov qab polarity?
Ironically feem ntau cov cuab yeej muaj qee hom kev tiv thaiv rov qab polarity ua nyob rau hauv. Feem ntau hauv daim ntawv diode thiab fuse. Qhov 'kev xav' yog tias yog qhov rov qab polarity txhaum tshwm sim,lub diode yuav ua, luv lub zog xa mus rau hauv av thiab ua rau lub fuse tawg - yog li tiv thaiv koj cov cuab yeej. Nws ua haujlwm.
Kev tiv thaiv rov qab roj teeb yog dab tsi?
