Hauv peb lub chaw soj ntsuam fais fab ntawm Wuxi Huipu Electronics Co., Ltd., peb ntsib tib lo lus nug yuav luag txhua lub lim tiam: "Vim li cas hloov cov khoom siv hluav taws xob xav tau siab - zaus transformers? Peb tsis tuaj yeem siv cov kab ib txwm siv - zaus?" Raws li cov chaw tsim khoom uas tau tsim ntau txhiab tus hloov pauv kev cai, peb cov lus teb yeej tsis los ntawm cov phau ntawv kawm- nws los ntawm kev tsim qauv, ntsuas cua sov, thiab cov lus pom zoo los ntawm cov neeg siv khoom ntau lawm kab.
Ob peb xyoos dhau los, ib tus neeg siv khoom tswj hwm kev lag luam tau thov kom peb txo qis lawv cov khoom siv hluav taws xob ntim los ntawm 30%. Peb pib sim ua kom zoo dua 50Hz transformer, tab sis txawm li cas los xij peb hloov kho cov tub ntxhais thiab winding, peb pheej tsoo saturation thiab thermal txwv. Tom qab ntawd peb thawb lub zaus hloov siab tshaj 100kHz, hloov mus rau siab - zaus ferrite cores nrog litz hlau windings, thiab lub ntim transformer poob ze li 70%. Tag nrho lub cev hnyav ua raws li kev cai. High-ntau zaus ua haujlwm tau hloov "lub zog ceev" los ntawm kev sib haum xeeb rau hauv kev suav tsis suav nrog engineering.
Qhov txiaj ntsig tiag tiag peb pom hauv kev xyaum
Thaum zaus nce, ob qho tib si tseem ceeb hla -section thiab winding lem txo proportionally. Qhov no hloov qhov sib npaug ntawm qhov poob ntawm tooj liab thiab core poob. Ntawm peb cov rooj zaum sim ntawm Huipu Electronics, siab - zaus transformers ua ke nrog cov niaj hnub mos- hloov cov topologies tsis tu ncua qhia 5-10% kev txhim kho kev ua haujlwm ntawm tag nrho cov khoom, nrog txo qis cov cua sov. Lub tswv yim tshwm sim? Cov dab dej kub me me, ua haujlwm ntsiag to, thiab lub neej ua haujlwm ntev dua.
High-ntau zaus tsim qauv kuj coj tau yooj yim tswj: ceev PWM teb, smoother dynamic load hloov, thiab yooj yim EMI lim kev koom ua ke. Tab sis ntawm no yog qhov peb tau kawm txoj kev nyuaj - zaus ntau dua tsis tau zoo dua. Parasitic capacitance, leakage inductance, thiab radiated cuam tshuam tag nrho nce nrog zaus. Nyob rau hauv peb lub prototyping theem, peb niaj hnub optimize winding lug, shielding khaubncaws sab nraud povtseg, thiab core air gaps kom pom qhov chaw qab zib ntawm efficiency, nqi, thiab EMC ua raws li.
Thaum High -Frequency Makes Sense for Your Design
Yog tias koj tab tom xaiv cov khoom siv rau kev hloov hluav taws xob, kev ua kom zoo, lossis kev sib ntaus sib tua thermal bottlenecks, tuaj rau peb nrog koj cov kev txwv tshwj xeeb. Peb tsis thawb "universal specs." Peb tsim cov kev cai daws teeb meem uas phim koj cov khoom sib dhos. Ntawm Wuxi Huipu Electronics, siab - zaus transformers tsis yog lub tswvyim -lawv tau tsim, sim, thiab pov thawj ntseeg tau ntawm cov kab ntau lawm.
