Qhov no US patent yog US counterpart ntawm yav tas los summed Suav patent CN110770860B, piav txog tib hybrid-cov ntaub ntawv reactor core tsim.
I. Abstract thiab Technical Field
Lub invention muab ib tug inductor magnetic core thiab ib tug inductor los daws cov teeb meem xws li tsis txaus siv qhov chaw, loj yoke loj, thiab kev pheej hmoo ntawm saturation thaum ntxov nyob rau hauv cov pa hlau hmoov core inductors.
Cov Qauv Tseem Ceeb: Cov tub ntxhais sib nqus uas muaj cov khoom sib txawv los ua kom zoo dua qhov kev ua tau zoo thiab qhov loj me:
Nruab nrab Kem: Muaj qhov sib nqus sib nqus flux ntom ntom (B1) ntau dua li cov yokes.
Upper thiab Lower Yokes: Muaj qhov qis qis qis sib nqus sib nqus flux ntom ntom (B2) dua li nruab nrab kem.
High Magnetically-Permeable Side Columns: Tsawg kawg yog ob sab kab yog siv los ua kom tiav cov hlau nplaum.
Cov txiaj ntsig: Cov qauv tsim txhim kho kev siv tus quab, ua tiav cov qauv kev cog lus ntau dua, thiab ua kom yooj yim ntau lawm.
II. Kev piav qhia thiab kev teeb tsa
A. Keeb kwm
Cov tsoos hlau hmoov core inductors, uas yog siv nyob rau hauv siab - zaus daim ntawv thov xws li photovoltaic inverters thiab hluav taws xob tsheb, txawm siv lub nplhaib inductor qauv (nyuaj rau huab hwm coj ntau lawm) los yog pawg thaiv hlau hmoov cores rau hauv cov duab square (E-core style). Cov tom kawg raug kev txom nyem los ntawm kev siv qhov chaw tsis zoo thiab muaj kev pheej hmoo ntawm cov khoom siv yoke saturating ntxov ntxov.
B. Kev daws teeb meem thiab teeb tsa
Lub invention siv cov khoom siv thiab cov qauv hybrid tsim:
Core Components:
Nruab nrab Kem (1): High saturation flux density khoom, piv txwv li, hlau hmoov core (xws li Sendust los yog FeSiAl). Qhov no yog qhov chaw coil (5) raug mob. Ib qho kev xaiv huab cua sib txawv tuaj yeem muab rau ntawm kab nruab nrab.
Upper Yoke (2) thiab Lower Yoke (3): Lower saturation flux density material, eg, ferrite.
High Magnetically-Permeable Side Kem (4): Tsawg kawg ob sab kab yog teem caij ntawm lub caij nyoog ntawm tus quab, txuas lawv cov npoo sab nraud. Cov kab no pab cuam tshuam cov hlau nplaum sib nqus los ntawm kev tsim ntau txoj hauv kev thiab ua los ntawm cov khoom siv nrog cov hlau nplaum permeability tsis qis dua 200, xws li ferrite lossis amorphous khoom.
Structure Integration los tiv thaiv Saturation:
Ob qhov kawg ntawm nruab nrab kem (1) yog muab tso rau hauv (los yog nkag mus rau hauv) lub sab sauv quab yuam (2) thiab tus quab qis (3).
Crucial Insertion Depth Condition (Claim 1): Qhov piv ntawm qhov tob tob (d) mus rau lub yoke thickness (D), Dd , yuav tsum siab tshaj los yog sib npaug B1 B1-B2 txhawm rau tiv thaiv qhov qis qis ferrite yoke cov khoom los ntawm kev saturated ntxov ntxov.
Inductor Assembly:
Lub inductor muaj xws li ib tug coil (5) qhov txhab nyob rau hauv nruab nrab kem (1).
Lub sab sauv thiab qis kawg ntawm lub kauj yuav muaj cov hlua khi kawg kom cais cov kauj los ntawm cov ntsiab lus tseem ceeb.
Tag nrho cov tub ntxhais sib dhos tuaj yeem muab ntim rau hauv ib lub tsev uas muaj cov kua nplaum rau kev sib xyaw ua ke.
C. Qhov zoo
Txhim Kho Kev Siv Yoke: Kev siv lub siab - saturation core (nruab nrab kem) thiab qhov tob ntawm nws qhov kev nkag mus rau hauv qis dua - saturation yokes tiv thaiv tus quab los ntawm saturating ntxov, zoo siv qhov chaw tseem ceeb.
Compact Structure: Yam tsawg kawg yog ob lub siab -permeability sab kab faib cov hlau nplaum sib nqus, tso cai rau tus quab thickness txo, uas ua rau cov cuab yeej compact dua.
Simplified Production: Cov qauv tsim ua kom yooj yim rau kev tsim khoom piv rau lwm yam hybrid lossis annular designs.
III. Main Claims
Claim 1 (Kev Cai ywj pheej): Ib qho inductor magnetic core, suav nrog tus quab sab sauv, tus quab qis, ib sab nruab nrab, thiab yam tsawg kawg yog ob lub hlau nplaum sib nqus-permeable sab kab, yam ntxwv hauv qhov ntawd:
Sab hauv nruab nrab yog muab pov tseg ntawm nruab nrab ntawm cov yokes.
Lub kauj yog qhov txhab ntawm sab hauv nruab nrab, thiab qhov sib nqus sib nqus flux ntom ntom ntawm nruab nrab kem (B1) yog siab tshaj qhov saturation magnetic flux ntom ntawm txhua tus quab (B2).
Sab sab yog muab pov tseg ntawm cov yokes, txuas lawv cov npoo sab nraud.
Crucially: Ob qhov kawg ntawm nruab nrab kem yog muab tso rau hauv lub yokes, thiab qhov tob qhov tob piv Dd yog siab tshaj los yog sib npaug rau B1B1-B2(qhov twg d yog qhov tob tob thiab D yog tus quab thickness).
Txoj Cai 2: Lub hauv paus ntawm daim ntawv thov 1, nyob rau hauv ob qhov kawg ntawm kab nruab nrab nkag mus los ntawm tus quab sab sauv thiab tus quab qis.
Txoj Cai 3: Qhov tseem ceeb ntawm daim ntawv thov 1, nyob rau hauv qhov sib nqus permeability ntawm txhua sab kem tsis qis dua 200.
Txoj Cai 6: Lub hauv paus ntawm daim ntawv thov 1, nyob rau hauv nruab nrab kem khoom yog cov hlau hmoov, thiab cov khoom siv quab yuam yog ferrite.
Nqe Lus Nug 12: Ib qho inductor siv lub inductor sib nqus core ntawm ib qho kev thov ua ntej, nrog rau lub qhov txhab coil ntawm nruab nrab kem.
