Kev tiv thaiv kev nyab xeeb capacitor rau EMC lim yog qhov tseem ceeb hauv EMC (Electromagnetic Compatibility) filtering, suppressing electromagnetic cuam tshuam (EMI), thiab txhim kho cov cuab yeej tiv thaiv - cuam tshuam muaj peev xwm. Lawv raug categorized rau hauvX capacitorthiabYog capacitors, txhua tus ua haujlwm sib txawv.
Core Functions
X Capacitor
Tshem tawm cov suab nrov sib txawv (nruab nrab ntawm L thiab N kab) nrog lub peev xwm loj dua (0.1μF-10μF). Lawv yog siv nyob rau hauv parallel nrog inductors los tsim LC filtering tes hauj lwm.
Y Capacitor
Txo cov suab nrov nrov (L / N rau hauv av PE) nrog me me capacitance (1nF–4.7nF) kom txo cov dej ntws tam sim no. Lawv txuas nrog hauv series nrog hom hom inductors thiab yuav tsum tsis qhib los tiv thaiv hluav taws xob poob siab.
Cov ntawv thov tseem ceeb
Hloov cov khoom siv hluav taws xob
X thiab Y capacitors, ua ke nrog hom hom inductors, lim input EMI.
Tsav Tsav
Tshem tawm cov hom tam sim no los ntawm kev hloov IGBT.
Khoom siv kho mob
Siv siab -kev ntseeg siab Y2 capacitor nrog kev tswj nruj tshaj li qhov tam sim no.
Kev txiav txim siab tsim
Kev xaiv
Xaiv cov capacitors uas tsim nyog qhov ntsuas hluav taws xob, lub peev xwm, thiab cov mem tes ua haujlwm (piv txwv li, IEC 61000-4-5 rau surges).
Daim ntawv pov thawj kev nyab xeeb
Xyuas kom ua raws li cov qauv (xws li UL, VDE) thiab siv cov ntawv pov thawj X1/Y1 lossis X2/Y2 capacitors.
Layout
Txo cov hlau lead ntev kom txo tau cov kab mob parasitic inductance thiab xyuas kom ntseeg tau tias muaj kev ruaj ntseg hauv av rau Y capacitors.
Tej Teeb Meem
Tshaj dhau
Txo Y capacitor capacitance lossis siv cov qauv tsim.
Kev lim dej tsis txaus
Optimize inductor inductance lossis capacitor resonance zaus.
Kev Nyab Xeeb Kev Nyab Xeeb
Tsis txhob hloov nrog cov tsis muaj -cov ntawv pov thawj capacitors.
Xaus
Kev tiv thaiv kev nyab xeeb capacitor rau EMC lim yog qhov tseem ceeb rau kev ua raws li EMC. X capacitors tuav cov suab nrov sib txawv, thaum Y capacitors hais txog hom suab nrov. Kev xaiv kom raug, ntawv pov thawj, thiab kev teeb tsa kom muaj kev lim dej zoo thiab cov khoom siv nyab xeeb.
