Centralized Inverter Ntawm Hnub Ci Inverter

Centralized inverters feem ntau yog siv rau hauv cov tshuab ntawm cov chaw nres tsheb loj photovoltaic (> 10kW). Ntau cov hlua 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 qis siv teb cov nyhuv transistors, thiab tib lub sij hawm siv DSP hloov dua siab tshiab maub los los txhim kho qhov zoo ntawm cov hluav taws xob tsim hluav taws xob, ua rau nws ze 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, nws raug cuam tshuam los ntawm kev sib piv ntawm cov hlua photovoltaic thiab ib nrab shading, uas ua rau muaj kev ua tau zoo thiab lub zog muaj peev xwm ntawm tag nrho photovoltaic system. Nyob rau tib lub sijhawm, lub zog tsim kev ntseeg tau ntawm tag nrho cov txheej txheem photovoltaic cuam tshuam los ntawm kev ua haujlwm tsis zoo ntawm pawg photovoltaic unit. Qhov kev tshawb fawb tshiab tshaj plaws yog kev siv qhov chaw vector modulation tswj thiab kev txhim kho ntawm cov tshiab inverter topology kev sib txuas kom tau txais kev ua haujlwm siab nyob rau hauv ib feem ntawm cov khoom thauj. Ntawm SolarMax (Thov txim Mike) centralized inverter, koj tuaj yeem txuas lub thawv photovoltaic array interface los saib xyuas txhua txoj hlua ntawm photovoltaic windsurfing hlua. 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, cov hlua no 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.
