Centralized inverter ntawm hnub ci inverter

Centralized inverters are generally used in large photovoltaic power station (>10 kW) system. Ntau cov hlua hluav taws xob photovoltaic txuas nrog rau DC cov tswv yim ntawm tib lub hauv nruab nrab inverter. Feem ntau, peb -theem IGBT fais fab modules yog siv rau lub zog siab. Lub zog me me siv lub teb cov nyhuv transistor, thiab DSP hloov dua siab tshiab maub los yog siv los txhim kho qhov zoo ntawm lub zog tsim, ua rau nws ze heev rau sine yoj tam sim no. Qhov loj tshaj feature yog lub zog siab thiab tus nqi qis ntawm qhov system. Txawm li cas los xij, vim qhov sib txuam ntawm cov hlua photovoltaic thiab ib nrab shading, nws ua rau kev ua tau zoo thiab hluav taws xob muaj peev xwm ntawm tag nrho cov photovoltaic system. Nyob rau tib lub sijhawm, lub zog tsim kev ntseeg tau ntawm tag nrho cov tshuab photovoltaic cuam tshuam los ntawm kev ua haujlwm tsis zoo ntawm qee pawg photovoltaic unit. Cov lus qhia kev tshawb fawb tshiab kawg yog kev siv qhov chaw vector modulation tswj thiab kev txhim kho ntawm cov tshiab inverter topology kev sib txuas kom ua tiav kev ua haujlwm siab nyob rau hauv ib nrab ntawm cov xwm txheej. Ntawm SolarMax centralized inverter, lub thawv photovoltaic array interface tuaj yeem txuas los saib xyuas txhua txoj hlua ntawm lub hnub ci vaj huam sib luag. Yog tias ib qho ntawm cov hlua tsis ua haujlwm zoo, lub kaw lus yuav xa cov ntaub ntawv xa mus rau cov chaw taws teeb tswj, thiab tib lub sijhawm, txoj hlua tuaj yeem nres los ntawm cov chaw taws teeb tswj, kom qhov tsis ua haujlwm ntawm cov hlua ntawm cov hlua photovoltaic yuav tsis txo thiab cuam tshuam rau kev ua haujlwm thiab lub zog tso tawm ntawm tag nrho photovoltaic system.
