Lub tshuab hloov pauv yooj yim yog tsim los ntawm cov hlau nplaum uas tuaj yeem nkag tau thiab ob txoj hlua. Ib qho ntawm cov cua txuas tau txuas nrog AC lub zog siv, hu ua thawj winding Np, thiab lwm qhov cua tuaj yeem txuas nrog lub nra, hu ua thib ob winding Ns.
Yog tias qhov kev sib tw tseem ceeb txuas nrog lub zog hluav taws xob ntawm AC qhov hluav taws xob Ui, lub tshuab hluav taws xob tsis muaj qhov thauj khoom, thiab lub zog hloov pauv Io tau tsim nyob rau hauv thawj qhov cua, thiab Io hu ua tsis muaj-load tam sim no. Qhov tam sim no teeb tsa qhov hloov pauv sib nqus uas tau kaw raws qhov sib nqus sib nqus ntawm cov hlau nplaum sib nqus. Qhov sib nqus sib nqus dhau los ntawm thawj qhov cua thiab qhov sib tw thib ob tib lub sijhawm. Lub zog hluav taws xob hluav taws xob tus kheej E1 tau tsim nyob rau hauv thawj qhov cua, thiab tus ncej thib ob tsim kev sib koom ua ke hluav taws xob hluav taws xob E2, tom qab ntawd E1: E2=Np: Ns. Np yog tus naj npawb ntawm qhov tig ntawm thawj qhov cua, thiab Ns yog tus naj npawb ntawm qhov tig thib ob ntawm qhov cua.
Cov hloov pauv ua lub luag haujlwm hauv kev nce qib, nqis qis, cais tawm, kho kom raug, hloov pauv zaus, theem hloov pauv, cuam tshuam qhov cuam tshuam, hloov pauv, khaws lub zog, thiab lim hauv cov hluav taws xob hluav taws xob.
A Classified by working zaus:
Lub zog hloov pauv zaus: ua haujlwm zaus yog 50Hz lossis 60Hz
Qhov nruab nrab zaus hloov pauv: ua haujlwm zaus yog 400Hz lossis 1KHz
Lub suab hloov pauv: ua haujlwm zaus yog 20Hz lossis 20KHz
Ultra audio transformer: siab dua 20KHz, tsis ntau dua 100KHz
Kev hloov pauv ntau zaus: Cov zaus ua haujlwm feem ntau yog siab dua KHz txog ntau pua KHz.
Kev faib tawm B los ntawm lub hom phiaj:
Lub zog hloov pauv: lub tshuab hloov pauv siv los muab lub zog xav tau los ntawm cov cuab yeej siv hluav taws xob
Lub suab hloov pauv: hloov pauv rau lub tshuab ua suab nrov thiab cov khoom siv suab
Pulse transformer: lub tshuab hloov pauv uas ua haujlwm hauv lub plawv dhia, thiab nws qhov kev yoj yoj feem ntau yog ib lub voj voos plaub fab
Cov hloov pauv tshwj xeeb: hloov pauv nrog lub luag haujlwm tshwj xeeb, xws li cov hloov pauv hloov pauv hloov pauv, ruaj khov hloov pauv, hloov pauv ib leeg dhau ib leeg, hloov pauv kab hloov pauv, thiab hloov pauv hloov pauv
Hloov hluav taws xob hloov hluav taws xob: siv rau kev hloov pauv hauv kev hloov pauv hluav taws xob hluav taws xob
Kev sib txuas lus hloov pauv: tus hloov pauv siv rau thaiv thiab lim hauv kev sib txuas lus network
