Diode rau pem hauv ntej thiab rov qab

Thaum qhov hluav taws xob rau pem hauv ntej tau thov, qhov hluav taws xob rau pem hauv ntej yog me me thaum pib ntawm tus yam ntxwv pem hauv ntej, uas tsis txaus los kov yeej qhov cuam tshuam ntawm hluav taws xob hauv PN kev sib tshuam. Lub pem hauv ntej tam sim no yuav luag xoom. Cov ntu no hu ua qhov chaw tuag. Qhov hluav taws xob rau pem hauv ntej uas tsis tig lub diode yog hu ua deadband voltage. Thaum qhov hluav taws xob rau pem hauv ntej yog ntau dua li qhov hluav taws xob tuag, qhov hluav taws xob hauv PN kev sib tshuam tau kov yeej, lub diode yog kev coj mus rau pem hauv ntej, thiab qhov tam sim no nce sai heev thaum lub zog nce. Nyob rau hauv qhov tam sim no ntau yam ntawm kev siv ib txwm, lub davhlau ya nyob twg voltage ntawm lub diode tseem yuav luag tas li thaum tig-on. Qhov hluav taws xob no yog hu ua rau pem hauv ntej voltage ntawm lub diode.

Rov qab

Thaum cov ntaub ntawv rov qab voltage tsis pub dhau ib qho ntau, qhov tam sim no los ntawm lub diode yog qhov rov qab tam sim no tsim los ntawm cov neeg nqa khoom tsawg tsawg. Vim tias qhov rov qab tam sim no me me, lub diode yog nyob rau hauv lub xeev tawm. Qhov rov qab tam sim no tseem hu ua thim rov qab saturation tam sim no lossis cov dej ntws tawm, thiab qhov rov qab saturation tam sim no ntawm lub diode cuam tshuam rau qhov kub thiab txias.
