Inverter, wanda aka fi sani da mai sarrafa wutar lantarki, mai sarrafa wutar lantarki, wani muhimmin bangare ne na tsarin photovoltaic.Mahimmancin aikin mai amfani da wutar lantarki shine canza wutar lantarki ta DC da aka samar ta hanyar hasken rana zuwa wutar AC ta amfani da kayan aikin gida.Duk wutar lantarki da aka samar ta hanyar hasken rana za a iya fitar da su ta hanyar maganin inverter.ta hanyar cikakken gada, gabaɗaya yana ɗaukar na'urar sarrafa SPWM ta hanyar daidaitawa, tacewa, haɓaka ƙarfin lantarki, da dai sauransu, don samun tsarin sinusoidal AC wanda ya dace da hasken wuta. mita mai ɗaukar nauyi, ƙimar ƙarfin lantarki don masu amfani na ƙarshe.Tare da inverter, ana iya amfani da baturin DC don samar da wutar AC don na'urar.
Tsarin samar da wutar lantarki na Solar AC ya ƙunshi bangarorin hasken rana, mai sarrafa caji, inverter da baturi;tsarin samar da wutar lantarki na hasken rana DC ba ya hada da inverter.Tsarin canza wutar lantarki ta AC zuwa wutar lantarki ta DC ana kiranta gyarawa, da'irar da ta kammala aikin gyara ana kiranta da'irar gyarawa, kuma na'urar da ta gane tsarin gyaran shine ake kira rectifier. Wanda aka fi sani da na'urar gyarawa ko kuma mai gyarawa.Haka kuma, tsarin canza wutar lantarkin DC zuwa wutar lantarkin AC shi ake kira da inverter, da'ira da ke kammala aikin inverter ana kiranta da inverter circuit, da kuma na'urar da ta gane tsarin inverter. ana kiransa kayan aikin inverter ko inverter.
Babban na'urar inverter ita ce inverter switch circuit, kawai na'urar inverter.Da'irar tana kammala aikin inverter ta hanyar kunnawa da kashe wutar lantarki.Kashewar na'urori masu sauyawa na lantarki yana buƙatar wasu nau'ikan tuki, wanda zai iya zama. ana daidaita su ta hanyar canza siginar wutar lantarki.Hanyoyin da ke haifar da sarrafa bugun jini ana kiran su da tsarin sarrafawa ko tsarin sarrafawa.Tsarin tsarin na'urar inverter, ban da na'urar inverter da aka ambata a sama da na'ura mai sarrafawa, shima yana da da'irar kariya, da'irar fitarwa, da'irar fitarwa, da'irar fitarwa da sauransu.
Ana amfani da inverter na tsakiya gabaɗaya a cikin tsarin tare da manyan tashoshin wutar lantarki (> 10kW).Yawancin gungu na hoto masu daidaitawa suna haɗe zuwa shigar da DC na inverter iri ɗaya.Gabaɗaya, babban iko yana amfani da ma'aunin wutar lantarki na IGBT guda uku, ƙaramin ƙarfi yana amfani da transistor tasirin filin, kuma yana amfani da mai sarrafa jujjuyawar DSP don haɓaka ingancin makamashin fitarwa na lantarki, yana mai da shi kusa da igiyoyin sinusoidal na yanzu.Babban fasalin shine babban girma. wutar lantarki da ƙananan farashi. Duk da haka, saboda ma'auni na jerin rukuni na photovoltaic da kuma shading mai ban sha'awa, yana haifar da tasiri da ƙarfin wutar lantarki na dukan tsarin photovoltaic. shafi matalauta aiki jihar na wani photovoltaic naúrar group.The latest bincike shugabanci shi ne modulation iko na sarari vectors, kazalika da ci gaban topological sadarwa na sabon inverters don samun high dace a partial load lokuta.A kan SolarMax ( SowMac) mai jujjuyawar tsakiya, ana iya ƙara akwatin ƙirar ƙirar hoto don saka idanu akan kowane jerin jerin rukunin hotovoltaic.Idan saitin su bai yi aiki yadda ya kamata ba, tsarin zai aika da bayanan zuwa na'ura mai ba da hanya tsakanin hanyoyin sadarwa, kuma zai iya dakatar da jerin ta hanyar sarrafa nesa, don kada ya haifar da gazawar ragewa da tasiri ga aikin da makamashin gaba daya. tsarin photovoltaic.
