Lub zog ua haujlwm ntawm hybrid inverters ncaj qha txiav txim siab cov nyiaj tau los ntawm kev faib tawm cov zog ntawm cov khoom siv tau ntxiv,} {8% hauv cov nqi hluav taws xob. Lub ntiaj teb muaj cov saw hlau, los ntawm cov hluav taws xob sib zog, sab saum toj los tswj cov kev txhim kho hluav taws xob, nce qib siab ntawm kev txhim kho hluav taws xob kom muaj zog ntawm 96% mus rau tshaj 98.5%. Qee qhov siab -}}}} Cov khoom siv tseem ceeb tshaj plaws rau cov kev siv hluav taws xob loj, los ua cov nqi thiab nce nyiaj tau zoo ".
1 Lub Zog Hluav Taws Xob Tiv Thaiv: Txo cov tub ntxhais ploj
Daim ntawv thov teev loj ntawm silicon carbide (sic) pab kiag hauv Suav teb. DC / DC thiab AC / DC MODULES ntawm qee hom lag luam hauv Inverter txhua tus neeg siv cov khoom noj lom neeg hloov chaw ntawm 60% thiab kev ua kom poob qis los ntawm 40%. Ntawm 220V / 50Hz kev khiav hauj lwm ntawm cov khoom siv ceg tawv (tsis muaj zog aws)) Qhov ntsuas ntsuas ntsuas ntawm cov photovoltaic cia kom zoo siv cov khoom siv hauv Shanghai qhia tau tias lub tshuab hluav taws xob ua kom zoo nkauj siv cov nqi hluav taws xob txhua xyoo.
Cov kev loj heev optimization ntawm gallium nitride (GAN) cov khoom siv hauv Tebchaws Europe. Lub siab - zaus} zaus siv lub zog ntawm lub teb chaws ntawm 200kHz, uas tau hloov kho cov khoom siv ntawm 200khz, uas tau hloov kho cov khoom siv ntawm 200khz, uas tau hloov kho cov khoom siv ua ke los ntawm 200k% Qhov kub siab kuj tsis kam ntawm Gan pab kiag li (Txo qhov hnyav los ntawm 15%, thiab ua tau raws li kev teeb tsa lub teeb ci tag nrho Daim ntawv thov ntawm kev ua lag luam photovoltaic hauv Munich qhia tau tias kev ua haujlwm ntau xyoo Xam ntawm tus nqi hluav taws xob muaj nqi ntawm 0.8 yuan / kW, lub tsev hluav taws xob siv hluav taws xob txhua xyoo yog 1600 yuan.
2 toxyology optimization: txo kev hloov pauv hluav taws xob poob
Lub tsib theem Topology Innovation ntawm Tebchaws Meskas. Rau siab siab - voltage thiab siab}}}}}} pa sharcology ntawm 1200v, thiab hloov pauv poob yog txo los ntawm 50%. Los ntawm "redundant hloov tsim qauv", thaum ib qho hloov lub raj tsis ua tiav, cov toppology tuaj yeem hloov mus rau qhov kev ua haujlwm muaj zog tab sis kuj tseem ua kom muaj kev ntseeg tau. Qhov ntsuas ntsuas ntsuas ntawm lub photovoltaic cia rau hauv Texas qhia tau tias European efficiency ntawm tsib qib kev nce qib li 25000 xyoo ib zaug nce ntxiv los ntawm 25000.
Tuam Tshoj "bi doval bound boosl boosl booslation todology qhuav". Tsim ib qho "ua ke Bidirectional Boos Boost Topology" rau tsev neeg qes qis dua " Ib txhij tau txais "synchronous rectification thev naus laus zis" thiab hloov cov kev ntsuas ntawm Mosfet, kev poob siab yog txo qis los ntawm 30%. Qhov kev ntseeg no txhim kho kev ua haujlwm ntawm tsev neeg cov invererers rau 98.2% thiab txo cov nqi los ntawm 15%. Raws li cov ntaub ntawv los ntawm e - kev lag luam platform, kev muag khoom ntawm cov inverter nce los ntawm kev xaiv hauv tsev hauv tsev neeg lag luam.
3 Tswj Algorithm Txawj Ntsev: Kev ua kom zoo ntawm lub zog txuag hluav taws xob
Nyiv "Adaptive MpPT algorithm". Lub photovoltaic mpPt module ntawm lub hybrid instlation adjection kev coj ua tau zoo (nrog huab kev soj ntsuam kev nce qib (nrog rau cov lus qhia qeeb (nrog cov lus teb nrawm dua thiab raug taug qab yog). MPTPT Efficiency tau txhim kho rau 99.5%, uas yog 1.2% siab dua ib qho algorithm. Qhov ntsuas tiag tiag ntawm faib cov photovoltaic project hauv Tokyo qhia tau tias lub xov tooj hluav taws xob txhua xyoo thiab nce qib ntxiv los ntawm 72 yuan / KW.
Thauj cov khoom siv hluav taws xob kom txuag hluav taws xob ua kom zoo nyob hauv Europe. Ib tug hybrid inverter nyob rau hauv lub teb chaws Yelemees muaj ib tug tsim cov ntaub ntawv siv hluav taws xob (xws li kev ua haujlwm siv hluav taws xob hluav taws xob (tshuab ntxhua khaub ncaws ua haujlwm " Piv txwv, thaum lub tshuab ntxhua khaub ncaws tau kuaj pom tias yog hom standby (hwj huam<10W), the inverter output voltage is automatically adjusted to 220V ± 2% (optimal load voltage range) to reduce standby losses; When the washing machine starts (with a power of 1500W), increase the response speed of the inverter output power to avoid additional losses caused by voltage fluctuations. The application of a household in Berlin shows that the algorithm improves the total energy efficiency of the household by 3% and saves 200 euros in annual electricity bills.
Cov kev hloov thev naus laus zis ntawm "Zog txhim kho kev txhim kho" hauv hybrid inverters yog txav los ntawm "rau" cov kab ke sib koom ua ke rau kev ua kom zoo dua ". Nyob rau yav tom ntej, nrog daim ntawv thov ntawm digital ntxaib kev ua kom zoo dua 99.5%, muab kev ua haujlwm hnyav dua "ntawm cov hluav taws xob ua haujlwm" ntawm cov faib khoom siv hluav taws xob.
