Niaj hnub no peb tshawb nrhiav daim ntawv thov ntawm qhov tseeb Circuit Court ua hauj lwm ntawm lub inductor, nyob rau hauv lub tiag tiag Circuit Court yog tsuas yog siv cov inductors los ntawm qhov tsawg-frequency tsis kam mus rau high-frequency, los ntawm DC tsis kam mus rau AC yam ntxwv ntawm kev tsim ntawm txawv circuits, lub Hauv qab no peb saib cov inductor hauv DC-DC boost circuit txoj cai ntawm kev ua haujlwm.

1. Hloov S raug kaw:

Raws li pom nyob rau hauv daim duab 1, thaum lub hloov S raug kaw, a, b, d ua ib lub voj kaw, lub hwj chim mov E los ntawm inductor tsim ib tug me me mus rau loj tam sim no i, lub sij hawm no t1 (xws li daim duab 2 t1 → t2 ) tam sim no zaus yuav tsum nyob ze rau lub high-frequency, raws li corrugator txoj cai (nce anti-txo tib yam), inductor tsim induced tam sim no nyob rau hauv cov kev taw qhia ntawm qhov opposite kev taw qhia ntawm tus thawj tam sim no i, induced tam sim no impedes qhov kev hloov nyob rau hauv lub i, inductor induced tam sim no kev taw qhia ntawm b → a, uas txhais tau hais tias lub hwj chim mov tam sim no i nyob rau hauv lub inductor rau hauv magnetic zog khaws cia kom txog rau thaum t2 thaum lub tam sim no kuv yog loj tshaj plaws, lub zog thaiv kuj yog qhov loj tshaj plaws, lub zog sib nqus khaws cia. nyob rau hauv inductor kuj yog qhov loj tshaj plaws. Tom qab ntawd t2 tom qab qhov tam sim no zoo li du, qhov zaus tam sim no nyhav rau DC, qhov cuam tshuam ntawm inductor tsis muaj zog, qhov dhau los ntawm qhov hloov pauv, qhov sib xyaw ntawm lub voj kaw ntws mus rau qhov tsis zoo ntawm tus ncej.Koj tuaj yeem tshawb xyuas cov khoom zoo sib xws ntawm peb.Tag nrho cov khoom Listsiv rau hauv DC-DC circuits.

2. Hloov S disconnect:

Raws li pom nyob rau hauv daim duab 3, thaum lub hloov S yog disconnected, a, b, d tsis yog ib tug kaw voj, lub hwj chim mov E ntws los ntawm inductor tam sim no los ntawm loj mus rau loj i, lub sij hawm no t3 (raws li nyob rau hauv daim duab 4. t3 → t4) tam sim no zaus yuav tsum nyob ze rau qhov siab zaus, raws li corrugator txoj cai (nce kev tiv thaiv qis ib yam), lub inductor tsim ib qho inductive tam sim no nyob rau hauv cov kev taw qhia tib yam li qhov qub tam sim no, induced tam sim no impedes kuv hloov, cov kev taw qhia ntawm inductor induced tam sim no rau lub a → b, uas txhais tau hais tias lub hwj chim mov tam sim no nyob rau hauv lub inductor yuav tau tig lub sib nqus zog pib hloov dua siab tshiab rau tam sim no, cov kev taw qhia ntawm tam sim no los ntawm lub diode a → b → c → d, piv txwv li, qhov voltage ntawm point b rau inductor induced electromotive quab yuam e ntxiv rau cov thawj fais fab mov voltage E, lawv ua ke los ntawm diode D1 mus rau lub capacitance C them, thiab tib lub sij hawm, cov zis voltage rau lub load U0, yog hais tias koj tsis coj mus rau hauv tus account lub diode lub voltage poob, U0 = E + e. uas induced voltage yuav qhia tau los ntawm qhov loj ntawm tus qauv A: Cov qauv no qhia tau hais tias qhov induced voltage loj thiab inductance loj, tus nqi ntawm kev hloov ntawm tam sim no ib chav tsev lub sij hawm yuav tshawb nrhiav ntxiv ntawm peb.Tshiab Centerrau kev nkag siab technical.

Yog li lub sij hawm no qhov voltage U0 yog siab tshaj qhov muab voltage E. Txog rau t2 thaum tam sim no kuv yog qhov tsawg tshaj plaws, lub zog thaiv kuj yog qhov tsawg tshaj plaws, lub zog sib nqus khaws cia rau hauv inductor kuj tseem yog qhov hloov pauv ceev kawg. Tom ntej no, los ntawm kev hloov mus tas li kaw, txiav tawm, koj tuaj yeem tso zis hluav taws xob tas li U0, thiab qhov hluav taws xob U0 siab dua li cov khoom siv hluav taws xob E, thiaj li ua si lub hom phiaj ntawm kev txhawb nqa.

3. Hloov mus rau hauv lub raj xa dej:
