DC Inverter yog dab tsi?
A DC inverter, feem ntau hu ua aphotovoltaic (PV) inverter los yoghnub ci inverter, yog ib tug sophisticated hwj chim hluav taws xob ntaus ntawv uas convertsdirect tam sim no (DC) generated los ntawm solar panels rau hauvHloov tam sim no (AC) haum rau kev sib txuas kab sib txuas lossis hauv zos noj. Raws li cov ntsiab lus tseem ceeb ntawm photovoltaic lub zog tsim tshuab, lub inverter ua ntau yam haujlwm tseem ceeb suav nrogMaximum zog taw tes nrhiav (MPPT), kab sib chaws synchronization, kev tswj fais fab zoo, thiab kev tiv thaiv kab ke.
Niaj hnub nimno PV inverters ua haujlwm nyob rau hauv qhov hluav taws xob input ranges los ntawm200V DC rau 1500V DC, nrog tso zis zog ntsuam xyuas los ntawm1kW thaj chaw nyob rau ntau-megawatt nqi hluav taws xob-scale central inverters. Lub conversion efficiency ntawm hwm inverters tshaj99%, nrog European-hnyav kev ua tau zoo (η) feem ntau yog los ntawm97% mus rau 98.5%.
Tsis zoo li DC-AC converters yooj yim, PV inverters koom nrogntse tswj systems uas tsis tu ncua optimize zog sau, saib xyuas kev noj qab haus huv system, thiab xyuas kom meej raws li evolving kab lis kev cai. Lub inverter tseem ceeb yog "lub hlwb" ntawm lub tshuab hluav taws xob photovoltaic, kev sib koom ua haujlwm ntawm lub hnub ci modules, roj teeb, loads, thiab daim phiaj siv hluav taws xob.

Yog vim li cas peb DC Inverter Manufacturing sawv sib nrug
Peb qhov chaw tsim khoom sawv cev20 xyoo kev tshwj xeeb nyob rau hauv photovoltaic zog hloov dua siab tshiab, xa inverters uas tshaj ntiaj teb no cov qauv los ntawm:
Kev paub txog lub zog semiconductor: Kev siv SiC MOSFET thaum ntxov, ua tiav 99% + kev ua haujlwm zoo thiab ua kom 1500V system architectures uas txo cov nqi BOS los ntawm 15-20%
Vertical kev koom ua ke: Nyob rau hauv lub tsev fais fab module sib dhos, sib nqus tivthaiv tsim, thiab automated PCB los ua ke kom ua tiav kev tswj xyuas zoo thiab cov saw hlau resilience
Kev ntsuam xyuas infrastructure: $ 10M + nqis peev hauv ATE systems, ib puag ncig chambers, thiab EMC lub chaw soj nstuam muaj peev xwm ua tiav IEC 62109 thiab IEC 61683 certification test
Grid Code kev coj noj coj ua: Kev ua raws cai nrog cov kab sib chaws hloov zuj zus (IEEE 1547-2018, VDE-AR-N 4110, G99) ua kom muaj kev lag luam nkag mus thoob 100+ lub teb chaws
Ntse zog innovation: Integrated roj teeb cia daws teeb meem, V2G muaj peev xwm, thiab virtual fais fab nroj tsuag (VPP) aggregation platforms rau lwm tiam zog systems
Digital manufacturing:Kev lag luam 4.0 kev siv nrog tag nrho traceability (ib yam khoom rau cov khoom tiav), kwv yees zoo analytics, thiab automated optical tshuaj xyuas kom ntseeg tau <100ppm tsis xws luag
Kev ntseeg tau tsom: 25-xyoo tsim lub neej, kev sim ua lub neej nrawm, thiab ua pov thawj MTBF> 100,000 teev

Hnub Ci Pump Inverter
Hu rau CDADA thiab cia peb ua koj lub chaw tsim khoom nrog rau cov khoom siv hnub ci twj tso kua mis Inverter. Cov khoom no yog 15kW-3-theem, MPPT-integrated, rau irrigation & dej. Tsis xav tau daim phiaj. IP65 xaiv tau, kev tiv thaiv qhuav-khiav, thiab kev saib xyuas tej thaj chaw deb. Zoo tagnrho rau kev ua liaj ua teb & cov haujlwm nyob deb nroog.
DC Inverter 0.75kW-630kW
Raws li tus neeg muag khoom txhim khu kev qha, CDADA's DC Inverter 0.75kW-630kW yog qib kev lag luam, DSP-raws li vector tswj, 4 hom (SVC/VC/V/F/Torque), Modbus, thiab nws pib-tuning. Rau cov twj, conveyors, extruders & high-precision tsav. Yuav kom tau txais lub Hoobkas ncaj nqe thiab kev daws teeb meem OEM, koj tuaj yeem tiv tauj peb.
CDADA yog DC Inverter cov chaw tsim khoom thiab cov chaw muag khoom hauv Suav teb. Peb lub Hoobkas ua haujlwm rau ntau hom kev lag luam xws li lub tshuab hluav taws xob, lub tsev automation, thiab kev tsim khoom lag luam, muab cov kev daws teeb meem OEM / ODM hloov tau.
