Ibibazo

Ni ubuhe buryo bwo gutondekanya n'ibipimo byo gushungura?

(1) akayunguruzo gato

Kuva kuri 0 kugeza kuri F2, amplitude-frequency ibiranga biraringaniye, birashobora gutuma ibice byinshyi biri munsi ya F2 binyura hafi ya bitamenyerewe, mugihe biri hejuru ya F2 byegeranye cyane.

(2) Akayunguruzo-hejuru

Bitandukanye na pass-pass yo gushungura, ibiranga amplitude-frequency biranga kuva kuri F1 kugeza kuri infinity.Iremera ibice bigize ibimenyetso hejuru yikimenyetso hejuru ya F1 kunyura hafi yubusa, mugihe abari munsi ya F1 bazahuza cyane.

(3) umurongo utambutsa akayunguruzo

Passband yayo iri hagati ya F1 na F2.Iremera ibice bigize ibimenyetso birenze F1 na munsi ya F2 kunyura mubitamenyerewe, mugihe ibindi bice byegeranye.

(4) bande ihagarika akayunguruzo

Bitandukanye no gushungura bande, guhagarika umurongo uri hagati yumurongo F1 na F2.Ihuza ibice byinshyi byikimenyetso hejuru ya F1 no munsi ya F2, naho ibindi bice bigize imirongo byanyuze hafi yabyo.

Niki amashanyarazi ya EMI?

Imashanyarazi ya elegitoroniki (EMI) iyungurura imbaraga nigikoresho cya pasiporo kigizwe na inductance na capacitance.Mubyukuri ikora nkibiri munsi-yungurura muyunguruzi, imwe ihuza uburyo-busanzwe bwivanga nindi ihuza uburyo butandukanye.Ihuza ingufu za rf mumurongo uhagarara (mubisanzwe urenze 10KHz) kandi ituma ingufu zumuriro zinyura hamwe na bike cyangwa nta attenuation.EMI amashanyarazi muyunguruzi niyo ihitamo ryambere kubashakashatsi ba elegitoroniki yo kugenzura EMI ikorwa kandi ikayangana.

Ni irihe hame ryakazi rya EMI power filter?

. mu nsinga zidafite aho zibogamiye (uburyo butandukanye);

Ni iki gikwiye kwitabwaho mugushiraho akayunguruzo?

Kugirango ugabanye guhangana nubutaka, akayunguruzo kagomba gushyirwaho hejuru yicyuma kiyobora cyangwa kigahuzwa nubutaka hafi yacyo hifashishijwe agace kegeranye kugirango hirindwe inzitizi nini ziterwa nubutaka buterwa ninsinga zoroshye.

Nigute ushobora guhitamo amashanyarazi?

Ibipimo byinshi bigomba gusuzumwa muguhitamo umurongo wumurongo.Iya mbere irapimwe voltage / igipimo cyumuvuduko, ikurikirwa no gutakaza kwinjiza, kumeneka (dc power filter ntabwo ireba ingano yumuyaga uva), ingano yimiterere, kandi amaherezo ni ikizamini cya voltage.Kubera ko imbere muyungurura muri rusange harimo kubumba, ibiranga ibidukikije ntabwo bihangayikishije cyane.Nyamara, ubushyuhe buranga ibikoresho byo kubumba hamwe nubushobozi bwa filteri bigira uruhare runini kubidukikije biranga amashanyarazi.

Ingano ya filteri igenwa cyane cyane na inductance mumuzunguruko.Ninini yubunini bwa coil ya inductance, nini nini ya filteri.
