Izina ryuzuye ryamicro-inverterni micro izuba rihuza inverter.Ikoreshwa cyane cyane muri sisitemu yo kubyara amashanyarazi kandi mubisanzwe yerekeza kuri inverter na module-urwego MPPTs ifite ingufu zitarenze 1500W.Micro-invertersni ntoya mubunini ugereranije nibisanzwe byegeranye.Micro-invertershindura buri module kugiti cye.Akarusho nuko buri module ishobora kugenzurwa yigenga na MPPT.Ibi bitezimbere cyane imikorere rusange.Muri icyo gihe,micro-invertersIrashobora kwirinda ibibazo bya voltage nini ya DC, imikorere idahwitse yumucyo, ningaruka ya barriel yo hagati.
Micro-invertersgucunga icyegeranyo cyingufu zizuba kumurongo wihariye kugirango wongere imikorere yizuba, aho gukora muri sisitemu yose nkuko inverter yo hagati yabikora.Mubihe byashize, uburyo bugoye bwo kugenzura bwakoreshejwe kugirango harebwe imikorere nini mugihe cyo gukusanya izuba byongereye ibiciro kandi bigabanya gufata mikorobe.Inzira zuzuzanya hamwe nibitunganyirizwa bishingiye kubisubizo byombi birakomeye kandi birahendutse kugirango bikemure logique yo kugenzuramicro-inverteribishushanyo.Igenzura rya voltage zitandukanye hamwe nubugenzuzi nabyo bitanga ibisubizo byuzuzanya kubyara ingufu ziva muri DC ziva mumirasire y'izuba.
Mu buryo bworoshyemicro-inverterIgishushanyo, gifatanye gifatanye gifata ibyuma bisubiza inyuma inverter itezimbere imbaraga nke za voltage ya DC iva mumirasire y'izuba hamwe na voltage yumuriro mwinshi usabwa na gride.
Nka gishushanyo mbonera cyo gutanga amashanyarazi,micro-inverterigishushanyo gisaba tekinike zitandukanye zo kunoza imikorere no kwizerwa.Ikoreshwa rya flake ya topback ikoreshwa, ifasha kugabanya imiyoboro ya rms ihindagurika binyuze muri yo, bityo ikongerera ubuzima bwa capacitori ya electrolytike muri ibi bishushanyo.Mubyongeyeho, ikoreshwa ryubuhanga bukora clamping ryemerera urwego rwo hejuru rwinshingano, rushobora gukoresha ibipimo bihanitse.Ibi birashobora kugabanya cyane umutwaro uriho kuruhande rwibanze hamwe na voltage umutwaro kuruhande rwa kabiri.
Kugirango habeho ingufu nyinshi zisohoka, inverter igomba kuba ishobora gusubiza kurimicro-inverter'skugenzura ibitekerezo.Iyi logique yashizweho kugirango igumane imbaraga za voltage nubu bigenda bihinduka hafi hashoboka kubintu byifuzwa byakozwe na algorithm ya MPPT.Icyingenzi cyane, grid-ihujwemicro-invertersigomba gushobora gutandukana na gride mugihe habaye imbaraga zo kunanirwa.Ibi biranga kurinda amakosa, nabyo, bisaba inverter kugira byibuze byibuze birenze urugero na volvoltage.
Igishushanyo cyamicro-invertersishyiraho igenzura, guhindura imbaraga nibisabwa gukora byagabanije gukoreshwa kwabo kera.Ariko, hamwe no gukwirakwiza ibisubizo byahujwe, abashushanya barashobora gukoresha ibikoresho bitandukanye bikwiye.Mugihe abitangiye gukora barashobora gutanga uburyo bwo kugenzura buhanitse hamwe nibikorwa bya MPPT bisabwamicro-inverters, ibishushanyo byimbaraga zo guhindura icyiciro bisaba ibikoresho bishobora umutekano kandi neza gutanga imikorere nibikorwa bisabwa kuri gride.Hamwe nurwego runini rwimikorere ihinduranya hamwe na PMICs zirahari, injeniyeri zirashobora gukora ibyiciro byiza, byigiciro cyinshi cyo guhindura imbaraga muburyo bwa micro-inverter.
