Core Power Conversion Applications hauv Switching Power Supplies
High-Frequency Transformer Cores: Ua raws li lub hauv paus tseem ceeb ntawm kev hloov cov khoom siv hluav taws xob, cov no pab txhawb qhov siab - zaus hloov hluav taws xob mus rau lub zog sib nqus thiab rov qab mus rau hluav taws xob. Lawv ua kom muaj hluav taws xob theem- nce / nce qib- nqes thiab hluav taws xob cais tawm, ua tiav kev hloov pauv hluav taws xob ntau dua 95% thiab txo qhov hnyav ntawm kev tswj xyuas thermal tsim.
Power Factor Correction (PFC) Inductor Cores: Siv nyob rau hauv PFC circuits los txhim kho lub zog ntawm cov khoom siv sab nraud thiab txo cov pa phem hauv daim phiaj hluav taws xob; haum rau cov ntawv thov xws li me me - mus rau - nruab nrab lub zog hloov hluav taws xob cov khoom siv hluav taws xob thiab UPS systems.
DC-DC Converter Zog-Storage Inductor Cores: Hauv topologies xws li Buck thiab Boost converters, cov cores no khaws lub zog sib nqus thaum lub hloov pauv transistor ua thiab tso tawm lub zog rau lub nra thaum nws raug tua, yog li smoothing cov zis tam sim no ripple thiab txhim kho lub zog mov stability.
Kev Siv Hluav Taws Xob EMC Lim Daim Ntawv Thov
Common-Mode Choke Cores: Siv los ua ntau hom- hom lim dej ntawm lub zog nkag / tso zis terminals, thaiv cov kab hluav taws xob surges (xws li cov los ntawm xob laim) thiab kab -coupled common-mode high-frequency interference, tiv thaiv xws li suab nrov los ntawm kwj propagating.
Differential-Mode Lim Inductor Cores: Tshem tawm qhov sib txawv-hom siab- zaus spikes ntawm cov kab hluav taws xob thiab lim tawm cov suab nrov thiab cov cim tsis xav tau, yog li txhim kho qhov purity ntawm cov khoom siv hluav taws xob.
Anti-Interference Ferrite Rings rau Fais Fab Chaw nres nkoj: Muab tso rau ib puag ncig cov tswv yim lossis cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tsheb, cov no nqus tau siab - lub suab nrov nrov, daws teeb meem xws li kev tshuaj ntsuam flickering lossis teeb liab cuam tshuam thaum them nyiaj.
