DC txuas capacitor

DC-Link capacitors tsim ib theem tseem ceeb hauv kev hloov pauv hluav taws xob rau ntau daim ntawv thov.

Cov ntawv thov uas nyuaj heev muaj tus nqi, ib puag ncig nyuaj, thiab kev txwv kev ntseeg siab nruj heev. Txawm hais tias cov qauv tsim hluav taws xob tuaj yeem siv ntau txoj hauv kev sib txawv, lub hauv paus tseem ceeb ntawm cov qauv hloov pauv hluav taws xob suav nrog DC-Link capacitors.

Cov capacitors DC-Link tuaj yeem txhim kho qhov ceev ntawm lub zog ntawm lub cev thiab daws cov teeb meem ntawm lub cev ntawm cov ripples uas tau tshwm sim los ntawm kev hloov pauv sai uas yog qhov tseem ceeb ntawm kev hloov pauv fais fab.

Qhov kev thov kom txuag hluav taws xob thiab cov khoom siv rov ua dua tshiab txhawb kom muaj kev tsim cov khoom xws li tsheb fais fab, PV converters, thiab cov tshuab hluav taws xob cua. Cov khoom no xav tau DC rau AC inverter kom ua tiav lub operating system. Cov lim dej thiab DC-link capacitors yog cov khoom tseem ceeb rau lub zog fais fab uas muab kev txhawb nqa rau qhov xav tau ntawm kev nce zog nrog cov hluav taws xob siab thiab cov dej ntws ripple.

Ua ib lub tuam txhab thev naus laus zis tshiab, CRE muaj pab pawg R&D thiab tsim khoom rau cov khoom siv hluav taws xob, thiab tsim cov chaw tsim khoom siv hluav taws xob R&D nrog cov koom haum tshawb fawb nto moo thoob ntiaj teb. Txog tam sim no, CRE muaj ntau dua 40 qhov kev tsim kho tshiab thiab cov qauv siv hluav taws xob thiab koom nrog kev tsim 10 lub teb chaws thiab kev lag luam tus qauv, tau ntawv pov thawj nrog ISO-9001, IATF16949, ISO14001/45001, thiab UL. Peb mob siab rau kev tsim ntau tus khub lag luam rau kev tsav tsheb tsim kho tshiab.

Cov khoom nrov ntawm CRE:
① DC-txuas capacitor
② AC lim capacitor
③ Kev khaws cia zog / Lub zog ntim hluav taws xob
④ IGBT snubber
⑤ Lub zog rov qab los
⑥ Lub capacitor txias dej

Yav dhau los: Cov lim dej thiab DC-link capacitors yog cov khoom tseem ceeb rau lub zog hloov pauv system
