Manma'å'ñao i Manma'å'ñao: Sa' hafa na i Gradient High-Silicon Steel (JNHF) Ha Na'guaha Zero Loss Deterioration gi i High-Frequency Reactors

I. I "Degradåsion i Prugråma" na Dilema

I manma'gås-ñiha gi i diniseño, ma'usa i dañuyan na tinige' put i materiåt siha yanggen ma selekta i materiåt siha. Lao, gi i manmafa'tinas gi i lina'la, diferentes na manma'gås-ta ni' manma'gås-ta manma'gås-ta ni' manma'gås-ta ni' manma'gås-ta ni' manma'gås-ta:

• Fe-Based Amorphous Alloys: Guaha un ultra-thin ribbon gauge ni' 0.025 mm ha', i amorphous ribbons ti gof takhilo' i linachi-ña. Lao, manma'å'ñao siha nu i estres mekaniku. Achokka' ma'usa i stress-relief annealing, i ma'a'atan gi C-cores, ma'a'atan, yan ma'a'atan, ha na'fanhuyong 68% na linachi (ginen i linachi i 1.31 W/kg asta 2.20 W/kg gi i ma'pos na core @ 20 kHz, 0.05 T).
• Thin-Gauge Grain-Oriented Steel (GO): Sa' put i fuetsan i magnetic anisotropy-ña, debi di u ma fa'tinas i GO steel komo wound C-cores. Suhettu gi i estres gi i lina'la' yan i inafekta nu i ina'ayuda, ha eksperensia un ~5% na inafekta nu i lina'la'-ña (ma'a'ñao ginen 9.75 W/kg asta 10.24 W/kg).
• Gradient High-Silicon Steel (JNHF-Core): Gi i ma'usa i precision stamping/cutting kombinidu yan i glued block-type stacked lamination structure (Stacked Core), i empirical na datos pruba na i JNHF ha na'guaha 0% na inañadi gi i core loss rate gi i finished cores (4.89 W/kg raw material vs.88 Wk.

II. Inadelanta gi i Estruktura: I Inafekta ni' I Dispersion gi i Air Gap Ha Na'fanlamen i Sobreheating gi i Lugåt

Para u ma prebeniyi i magnetic saturation gi papa' i takhilo' na DC na kurentå siha, debi di u ma na'halom i aire gi i magnetic circuit gi i DC/AC high-frequency reactors. Lao, i konbensionåt na aire ni' ma'a'atan ha na'fanhuyong fringing flux (leakage flux), ya ha na'fanhuyong dangkolo na eddy currents gi i laminasion siha gi fi'on-ña ya ha na'fanhuyong hot spots.

Konsentråo na Air Gap kontra i Multi-Gap na Dispersion na Inayek

1. C-Cores ni' ma'usa: Ma'a'atan i geometry-niha, ya i C-cores ma'a'atan gi 1 pat 2 na dångkolon aire ni' ma'a'atan. Yanggen i lina'la' i gap dumidog (pot hemplo, asta 4 mm), i intenso na fringing flux ha na'fanlamen i core loss gi i amorphous yan GO steel cores para u dumidog eksponensiatmente.
2. JNHF Glued Block-Type Stacked Cores: Ma'usa i non-oriented (NO) na naturåt yan i mas maolek na mekaniku na kinalamten i high-silicon steel, ya siña ma'konfigura i JNHF komo un multi-segment assembled block core, ya ha dibidi un dångkolon air gap gi meggai na dikike', distributed gaps:
   • Para i parehu na lina'la' i aire (pot hemplo, 4 mm), i lina'la' kada na gap ma na'menos;
   • I fringing flux ma'a'atan, ya ma'a'atan i fringing-induced na piniti;
   • I risultan i prublema siha ha konfitma na yanggen i lina'la' i gap ha na'lå'la' i lina'la'-ña ginen 0 mm asta 4 mm, i kurba ni' ma na'suha gi i JNHF ti gof takhilo', ya ha na'fanhuyong mas dikike' na lina'la' gi i mas takhilo' na lina'la' gi i aire ki i amorphous yan GO steel cores.

III. Bentaha gi i Dos na Permeabilidåt: Mas Takhilo' na Inestotban DC yan Takhilo' na Induktansia

Para i DC na reactor siha gi i power electronics (put hemplo, Boost circuits, PFC inductors, yan DC-DC converters), i DC bias na kinalamten i core direktamente ha go'te i estao inductance gi papa' i takhilo' na load currents.

I prublema siha gi 20 kHz, 0.01 T ha na'annok:

• Amorphous & GO Steel Cores: Yanggen i DC bias ampere-turns mas ki 2,000 A�t, i inductance (�H / turn²) dumiminuyi.
• JNHF Gradient Cores: Gi papa' i takhilo' na DC bias (ginen 2,000 A�t asta 4,000 A�t), i JNHF ha na'fanli'e' un eksepsionåt na suette na magnetic saturation roll-off, ya ha na'siguru na takhilo' i residual inductance levels.

Mekanismo: Taimanu na siña ha na'guaha JNHF i takhilo' na resistensian bias yan takhilo' na inductance?

I JNHF ha u'usa un estrukturan gradient silicon gi todu i tina'lo' i papet ( takhilo' na silicon ~6.5% Si gi i hilo', takpapa' na silicon gi i sanhilo'):

1. Bahu na DC Permeability (�_max = 4,100): Yanggen makompara yan i standard silicon steel (37,000) yan i amorphous alloys (300,000), i JNHF guaha mas dikike' na DC permeability, ya ha na'i fuetsan intrinsic na resistensia para i DC magnetic saturation.
2. Takhilo' na Permeabilidåt gi i Takhilo' na Frekuensiha (�_20kHz = 1,500): Gi 20 kHz, i JNHF ha na'guaha un takhilo' na permeabilidåt AC ni' 1,500 (mas maolek ki i GO steel's 1,110), ya ha na'siguru na guaha abundante na inductance gi papa' i takhilo' na frekuensian ripple.
