Qhov kev taw qhia ntawm lub tshuab pulse transformer

Lub npe hu ua pulse transformer yog ib qhov kev siv hluav taws xob broadband. Kev hloov kev siv rau kev sib txuas lus, nonlinear distortion yog ib qho tseem ceeb qhia, vim li ntawd qhov kev hloov ua lub luag haujlwm yuav tsum ua hauj lwm ntawm thawj zaug ntawm qhov tseem ceeb, yog li ntawd txawm tias ib lub tshuab hluav taws xob muaj zog zoo li ib lub tshuab hluav taws xob muaj peev xwm loj heev . Ntxiv rau kev xav txog cov yam ntxwv ntawm qhov kev hloov ntawm lub cav, Nws tseem yog ib qho tseem ceeb rau kev txo qhov poob .

Nqa cov tshuab pa mem tes:

Cov qauv ntawm cov tshuab luam yeeb pulp yog zoo li kev tswj hluav taws xob. Cov kev siv tshuab hluav taws xob thiab cov txuj ci sib txig sib txuam ua tus tsim qhov tseem ceeb ntawm cov tshuab pulse. Txawm li cas los xij, feem ntau ntawm cov tshuab pulse transformer ua rau lub nplhaib, thiab cov khoom yog feem ntau yog permalloy los yog Mn-Zn-hlau-pa-magnesium ceramic; Cov cua dub yog ob tog los yog peb sab, thiab qhov kev sib tw ntawm peb sab yog feem ntau yog muab los txhim kho cov kev ua tau zoo. Tus cwj pwm ua dab tsi yog hloov qhov polarity ntawm lub teeb liab ntawm qhov tso zis kawg ntawm kev hloov cov kev taw qhia winding ntawm lwm qhov kev sib tw.

Mem tes transformer ua hauj lwm txoj cai:

Txoj kev ua hauj lwm ntawm kev siv lub tshuab pulse siv cov kev ua kom sib luag ntawm cov tub ntxhais los hloov cov tswv yim sine wave voltage rau hauv ib lub cav nrog lub tshuab nqaim pluaj zoo li cov hluav taws xob. Nws tuaj yeem siv rau kev sib tsoo ntawm kub hnyiab, triggering ntawm thyristors, thiab lwm yam. Lub qauv pulse transformer yog xws li tus thawj ntses yog nyob rau ntawm ib sab qauv ntawm lub thawv hlau uas muaj ib sab loj, ib sab ntawm cov ntaub ntawv permalloy muaj ib feem me me uas yog ib qho yooj yim uas tau yooj yim heev, thiab ib qho sib txawv sib nqus tau teem ntawm ob kab. Txuas ntxiv rau cov paib thiab lub zog, qhov input voltage u1 yog sine wave uas ua rau lub cev xoo hluav taws xob nyob rau sab laug. Qhov sib nqus kua nplaum Φ2 nyob rau hauv txoj kev tseem ceeb yog saturated heev thiab yog ib lub roob sab saum toj. Nws tsuas hloov nyob ib ncig ntawm zero thiab tam sim ntawd saturates mus rau qhov nqi tas li. Thaum lub Φ2 xoom-qhov kev sib tshuam tseem ceeb, yog ib txoj hlab pas nqaim nqus hlau electromotive yuam e2 yog vim li cas rau qhov kev sib tw secondary. Qhov sib txuam sib nqus muaj qhov sib txawv ntawm huab cua, thiab nws muaj kev hloov linearly, zoo ib yam li sib nqus nqus, thiab nws txoj haujlwm yog los xyuas kom meej tias Φ1 yog sine wave.

Lub hom phiaj tseem ceeb ntawm cov tshuab luam yeeb:

Cov tshuab pa mem tes siv dav siv hauv kev siv radar thiab kev hloov technology; kev txuam ntawm kev ua haujlwm tsis txaus ntseeg thiab kev noj zaubmov kev noj zaubmov impedance; raising los yog txo cov kev ntsuas hluav taws xob; hloov pulse polarity; kev rho tawm ntawm cov khoom siv hluav taws xob txuas ntxiv thiab cov thawj kev sib cog lus siv ob peb lub nrawm nrab ntxiv kom tau theem Kev Txheeb; kev rho tawm ntawm DC khoom ntawm lub hwj chim; muaj zog khi rau nruab nrab ntawm lub collector (anode) thiab lub hauv paus (lub qhov rooj) nyob hauv lub transistor (los yog lub tsho) pulse oscillator; siv ob peb qhov kev sib tw ua kom tau ob peb qhov sib txawv Qhov txiaj ntsig ntawm qhov nqi ua rau cov tswv yim zoo ntawm lub phaj thiab lub qhov rooj ntawm lub raj, los yog tus neeg khoom thiab lub hauv paus ntawm transistor, los tsim kom muaj qhov oscillation; raws li lub hwj chim synthesis thiab kev hloov dua siab tshiab.
