1: 1 lossis 1: 6 piv? Cov mem tes Transformer Phau Ntawv Qhia rau Cov Hluav Taws Xob

Xaiv cov kev hloov pauv tsis ncaj ncees lawm hauv cov tshuaj hloov mem tes tuaj yeem ua rau muaj kev sib raug zoo rau kev ua kom muaj zog {% ua rau muaj 30% zog, teeb meem tseem ceeb. ThaumTso - hauv cov chaw muag khoomTsom xam rau RF rho tawm, cov tshuab hluav taws xob sib ntaus sib tua sib ntaus sib tua hluav taws xob. Nov yog xaiv ntawm 1: 1 thiab 1: 6 tsis muaj kev teeb tsa yam tsis muaj kev cuam tshuam koj tus qauv.

Cov teeb meem tseem ceeb: efficiency vs. voltage nce

1: 1 piv txwv (tsom kho)

Zoo:

Ze - xoom theem ua haujlwm (tseem ceeb rau pwm tswj loops)

Kev Tsawg Tshaj Kev Lag Luam Kev Lag Luam (<2% energy loss)

Nplij txwv:

Tsis muaj voltage nplai -}} yuav tsum muaj cov peev txheej ntxiv

Zoo tagnrho rau:

Rooj vag tsav ncig (piv txwv li, iGBTS nyob rau hauv 10kW inverters)

Cov cuab yeej kho mob yuav tsum tau ua IEC 60601-ua raws kev sib cais

1: 6 Piv (Voltage Txhawb)

Zoo:

Cov kauj ruam tshuab voltage 6 × (piv txwv li, 5V → 30V rau GAN FET cov tsav tsheb)

Txo cov kev ntxhov siab tam sim no los ntawm 83%

Nplij txwv:

Kev ua txhaum cai cuam tshuam ua rau EMI (kho tau nrog cov sornbers)

Zoo tagnrho rau:

Flybeback Converers (230Vac / 50Hz Cov Lus Qhia)

Hnub ci microinverters nrog 12v → 80V hloov dua siab tshiab

Cov cai tsim tseem ceeb rau kev xaiv cov kev xaiv

Txoj cai # 1: phim impedance, tsis yog tsuas yog voltage xwb

Mismatched impedance qhia lub zog → kho cov cores kub.

Cov Qauv:Z_p/Z_s = (N_p/N_s)²

Tus yam ntxwv: 50ω tus tsav tsheb mus 5ω thauj tau cov khoom lag luam 1: 3.16 piv (tsis yog 1: 6).

Txoj Cai # 2: Ua Ntej Tseem Ceeb Tshaj Plaws Cov Ntxaij

Cov kev ntsuas siab (1: 6) Thov cov corger loj kom tsis txhob muaj kev lom zem heev ntawm cov zaus tsawg zaus.

Ferrite core loj thiab cov lus qhia piv txwv:

Txoj Cai # 3: Muv EMI los ntawm Kev Lag Luam Kev Lag Luam

1: 6 Transformers Tsim 5 × siab dua DV / DT → radiate 30db suab nrov dua.

Txhim kho: RC snubbers (10ω + 100 pf) lossis thaiv bobbins.

Thaum mus kev cai: tshaj qhov qauv kev sib piv

Qib 1: 1/1: 6 Transformers swb rau hauv hybrid Scararios:

Rooj plaub 1: 48v lub tshuab roj teeb xav tau 1: 2.5 sib piv rau 120V kev caij tsheb npav.

Rooj plaub 2: 3-theem invererers xav tau 1: 0.5Kauj -} downmuab cais nyob ib leeg.

Kev hloov pauv hloov kho qhov no los ntawm:

Hloov kho tig rau frumactional ratios (piv txwv li, 1: 1.8)

Using triple-insulated wire for >5KV Kev Rho Tawm (IEC 61558)

Engedding Kub Sensors Hauv Cores (NTC 10Kω)

TusTso - hauv cov chaw muag khoomZaj Lus Qhia: Cov teeb meem precision

Tsuas yog rf engineers vetTso - hauv cov chaw muag khoomRau 0.1dB rho tawm ruaj khov, cov neeg tsim hluav taws xob yuav tsum xav tau:

Piv txwv tsis kam: ± 1% (tsis yog kev lag luam - txheem ± 5%)

Cov Khoom Siv Tseem Ceeb: 3F45 ferrite for >200kHz vs. N87 rau<100kHz

Kev Ntsuas Xyuas Ib nrab: >1500V Rho Tawm Qhov Siv Tau

Tag

Ib 1: 6 piv cov hluav taws xob voltage tab sis txaus ntshai EMI; 1: 1 paub meej cov cim kev ncaj ncees tab sis kev txwv tsis pub luam tawm. Txog lub hom phiaj {{5 5}} tseem ceeb (kev ua haujlwm / tub rog), kev sib piv sib piv, kev sib piv sib piv txwv tiv thaiv tus nqi rov qab. Tus khub nrogTso - hauv cov chaw muag khoomLeej twg nkag siab txog kev rho tawm ob tog RF thiab fais fab hloov dua siab tshiab ua rau lub zog rau choj cov ntiaj teb no.
