CEA ntawm INES tau tsim thawj tus qauv ntawm 400W photovoltaic microinverter ua nrog GaN transistors tsim los ntawm CEA lub chaw soj nstuam ntawm Leti.
Nws muaj lub zog muaj zog ntawm 1.1 kW / l thiab kev ua haujlwm ntawm 97 feem pua (piv rau {}. 3 thiab 95 feem pua rau cov thev naus laus zis).
Lub photovoltaic panels tsim hluav taws xob ncaj qha. Ib qho inverter yog xav tau los txuas lawv mus rau daim phiaj hluav taws xob, uas muab kev hloov pauv rau cov neeg siv khoom. Cov kauj ruam hloov dua siab tshiab no ua rau lub zog poob uas tuaj yeem txo qis nrog cov khoom tshiab.
Loj hauv av-mounted photovoltaic cov nroj tsuag nrog rau cov nroj tsuag tau nruab rau hauv cov tsev kawm qib siab lossis cov tsev lag luam tau nruab nrog "centralized" lossis "string" inverters thiab txuas nrog peb-theem hluav taws xob daim phiaj.
Rau kev teeb tsa hauv tsev, cov khoom siv hluav taws xob muaj nyob hauv ib theem thiab tsis tshua muaj hluav taws xob. Photovoltaic panels ntsia rau ntawm lub ru tsev muaj peev xwm ua rau ntau qhov ntxoov ntxoo, ua rau poob. Yog li ntawd, nws yog qhov nthuav kom koom nrog lub inverter rau txhua lub vaj huam sib luag photovoltaic uas tso cai rau kev ua haujlwm ywj pheej ntawm cov modules, ib qho kev pom zoo ntawm cov khoom tsim tawm thiab kev ua haujlwm modular (yooj yim hloov). Hom inverter no, nrog lub zog ntawm 200 txog 500 W, hu ua micro-inverter. Nws yog ntsia rau sab nraum qab ntawm txhua lub vaj huam sib luag.
Cov khoom siv no siv cov khoom tseem ceeb: lub zog semiconductors.
Lub CEA ntawm INES tab tom tsim cov tiam tshiab inverters kom txo tau tus nqi, txhim kho kev ua haujlwm ntawm lub zog thiab txhawb txoj kab hluav taws xob. Lub compactness ntawm cov khoom no kuj yog ib qho teeb meem nyob rau hauv thiaj li yuav tswj cov kev cuam tshuam ntawm installation thiab txij nkawm nqi ntawm cov fais fab nroj tsuag, thiab txo cov kev siv ntawm cov ntaub ntawv.
Peb cov kev tshawb fawb tsom mus rau cov khoom siv hluav taws xob thiab siv "qhov sib txawv loj" semiconductors xws li silicon carbide (SiC) thiab gallium nitride (GaN), tshwj xeeb yog cov tsim hauv CEA-LETI lub chaw soj nstuam hauv Grenoble.
GaN thev naus laus zis yog ib qho ntawm cov cuab yeej hu ua "wide-gap" technologies (broadband semiconductors), uas thawb cov kev txwv ntawm lub zog semiconductors siv silicon.
Nws tso cai rau miniaturization thiab nce zog efficiency thaum txo nqi.
Lub photovoltaic thiab automotive industries (nrog lub tsheb fais) yog lub ntsiab kev loj hlob tsav tsheb rau cov tshiab converters raws li GaN los yog SiC semiconductors.
CEA-Leti muaj lub xeev-ntawm-tus-kos duab epitaxy (600V thiab 1200V) thiab thev naus laus zis los tsim GaN 600V diodes thiab fais fab transistors uas ua tau zoo dua silicon sib npaug. Nrog rau cov cuab yeej coplanar no, nws yuav ua tau kom lub zog tivthaiv "smarter" nrog kev tiv thaiv (kub, voltage, tam sim no, thiab lwm yam) thiab tswj (tsav) zog. Nws kuj tseem tuaj yeem tsim cov kev cuam tshuam hluav taws xob bidirectional uas tsis muaj nyob rau tam sim no.
CEA ntawm INES tau tsim kom muaj qhov kub thiab txias dynamic characterization lub rooj ntev zaum rau cov GaN transistors tshiab, nrog rau thawj tus qauv ntawm 400W photovoltaic microinverter siv cov transistors ua los ntawm CEA Leti's Cheeb Tsam Cheeb Tsam. Qhov no microinverter muaj ob theem hloov dua siab tshiab:
- Ib theem DC / DC suav nrog 5 GaN 100V transistors
- Ib theem DC / AC suav nrog 4 GaN 650V transistors
Ib tiam thib ob ntawm microinverters yog npaj rau qhov kawg ntawm 2022, siv GaN transistors optimized. Lwm qhov ntau thiab tsawg ntawm inverters tseem yuav raug tsom txhawm rau ua pov thawj lub tswv yim ntawm lub zog siab dua.
Cov thev naus laus zis no xav tias yuav ncav cuag lub khw los ntawm 2025-2027. Lub sijhawm no, cov kws tshawb fawb ntawm CEA-Leti thiab CEA-Liten ntawm INES yuav txhim kho cov thev naus laus zis thiab tsim kom muaj kev sib koom ua ke ntawm kev tswj hwm digital. Pab neeg no yuav nthuav tawm cov qauv tshiab hauv xyoo tom ntej.
Txoj haujlwm no yog cov ntsiab lus ntawm patents thiab ntau cov ntawv thiab nthuav tawm ntawm cov rooj sib tham thoob ntiaj teb (PCIM, EPE).
