Tshwj xeeb electromagnetic coil 0210B rau tub yees valve

Dab tsi yog lub luag haujlwm tseem ceeb ntawm inductance ntawm electromagnetic kauj?

Dab tsi yog lub luag haujlwm tseem ceeb ntawm inductance ntawm electromagnetic kauj? Lub inductance ntawm lub kauj, qhov tseeb, yog hais tias thaum ib tug tam sim no dhau los ntawm cov hlau, ib tug hlau nplaum yuav tsim nyob ib ncig ntawm lub kauj.

Feem ntau, lub kauj yuav muab qhwv rau hauv cov duab cylindrical, lub hom phiaj ntawm kev txhim kho cov hlau nplaum sab hauv. Nws yog tsim los ntawm cov neeg xyuas pib (uas tuaj yeem yog cov xov hlau liab qab lossis cov xov hlau pleev xim) nyob ib ncig ntawm lub raj insulating, thiab feem ntau nws tsuas muaj ib qho winding xwb. Cia peb tham txog nws lub luag haujlwm tseem ceeb hauv kev nthuav dav.

Ua ntej tshaj plaws, choke:

nyob rau hauv cov kab hluav taws xob tsawg, nws tuaj yeem siv los thaiv qhov tsis tshua muaj zaus hloov tam sim no. Yog li ntawd lub pulsating DC Circuit Court yuav hloov mus rau hauv ib tug ntshiab DC Circuit Court, yog li ntawd nws muaj peev xwm paub qhov tso zis ntawm lub rectifier Circuit Court ntawm ob lim capacitors, thiab lub choke coil thiab lub capacitor muaj peev xwm tsim ib tug lim circuit. Raws li rau high-frequency Circuit Court, nws muaj peev xwm tiv thaiv tau cov high-frequency tam sim no ntws mus rau qhov tsawg-zaus kawg.

Thib ob, filtering:

lub lim dej muaj nuj nqi zoo ib yam li cov kev xav saum toj no. Nws lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov kev hloov pauv hloov pauv DC tam sim no kom ntws mus rau qhov ntshiab DC Circuit Court uas muaj ob lub electrolytic capacitors, kom lub Circuit Court tau yooj yim thiab cov nqi tsim khoom tuaj yeem txo. Ntshiab DC tam sim no tuaj yeem tau txais los ntawm kev them nyiaj thiab tso tawm lub capacitor thiab tig rau DC tam sim no los ntawm strangling electromagnetic coil, thiab DC tam sim no tuaj yeem ua kom zoo los ntawm kev tiv thaiv AC.

Thib peb, poob siab:

rectification yog hloov AC rau DC, thiab poob siab yog hloov DC rau AC. Lub Circuit Court uas ua tiav cov txheej txheem no yog hu ua cov khoom cuam tshuam. Lub waveform ntawm cov cuab yeej cuam tshuam tuaj yeem muab faib ua ntaiv nthwv dej, square nthwv dej, zoo rotating yoj, sawtooth yoj thiab lwm yam. Qhov ntau zaus tuaj yeem yog ob peb hertz lossis kaum ntawm gigahertz.

Dab tsi yog lub luag haujlwm tseem ceeb ntawm inductance ntawm electromagnetic kauj? Los ntawm cov lus qhia saum toj no, peb tuaj yeem paub tias nws ua lub luag haujlwm tseem ceeb hauv throttling, lim thiab oscillation.
