Power Inverters, i n’a fɔ fɛn kolomaw Power Electronics foro la, olu bɛ baara kɛ kosɛbɛ baarakɛcogo la i n’a fɔ fototalan sɔrɔli, kuran mɔbiliw, ani kuran minnu tɛ se ka tiɲɛ (UPS). U jɔcogo bɛ nɔ bila fɛn caman tigɛli nafama ni dannaya la. Dunanw ka jagokɛlaw fɛ, inverterw ka sigicogo jɔnjɔn faamuyali bɛ dɛmɛ ka kiliyanw magow ɲɛ ka ɲɛ ani ka fɛɛrɛko kumaɲɔgɔnya ɲuman sabati.
Inverter ka core structure bɛ se ka tila ka kɛ module belebele duuru ye: donnasira, DC{0}}DC converter, inverter bridge, output filtering, ani control system. Donda kafoda de bɛ DC fanga doncogo sabati (i n’a fɔ batiriw walima fototalanw) wa a ka c’a la, EMI filɛriw ni surge lakanani minɛnw bɛ sɔrɔ walasa ka don fanga saniya. DC{3}}DC convertisseur (ni a mago bɛ a la) bɛ tension hakɛ ladilan walasa ka inverter stage nata wajibiyalenw dafa.
Inverter bridge ye inverter "dusukun" ye, min bɛ Kɛ ni fanga switching minɛnw ye i n'a fɔ mosfets ani IGBTs, minnu bɛ DC fanga 'kɔnɔ ka AC 'kɔnɔ ka Tɛmɛ High-Frequency switching fɛ. Topidiya minnu bɛ kɛ tuma caman na, olu ye tilancɛ-Bridge, Full{3}}Bridge, ani saba{4}}Fase Bridge ye. Ni inverters sugandi diɲɛ jago kama, a nafa ka bon ka fura ɲuman sugandi ka da sugu laɲinilen ka tension sariyaw kan (misali la, 220v/50Hz walima 110V/60Hz).
Output filter bɛ high-Frequency harmonics (fɔrini) caman bɔ ni inducteurs (inducteurs) ni capacitors (kondensatɛriw) ye, o bɛ bɔli AC fanga surunya sine wave (sine wave) la. O nafa ka bon kosɛbɛ minɛnw na minnu bɛ se ka kɛ fɛn ye walima minnu bɛ kɛ ni grid ye-Sɛbɛnw bɛ ɲɔgɔn sɔrɔ. A laban na, kunnafoni-falen-falen-minɛn (a ka c’a la, a sinsinnen bɛ DSP walima MCU kan) bɛ sɛgɛsɛgɛli kɛcogo, fasa, ani tension ladilan waati yɛrɛ la walasa ka bɔli sabatilen sɔrɔ, ani ka lakanafɛnw fara ɲɔgɔn kan i n’a fɔ voltage tɛmɛnen, kuran tɛmɛnen, ani surun{4}}Circuit lakanani.
Ka bɔ diɲɛ jago siratigɛ la, inverter sigicogo wajibiyalenw bɛ danfaraba la suguw kɔnɔ: Erɔpu ni Ameriki kuntigiw bɛ baara kɛcogo ɲuman ni seereyaw labatoli bila jɔyɔrɔ fɔlɔ la (misali la, UL ni CE), k’a sɔrɔ sugu minnu bɛ ka bɔ kɛnɛ kan, olu bɛ se ka musakaw ni muɲuli bila jɔyɔrɔ fɔlɔ la. Nin sigida ninnu faamuyali bɛ se ka feerekɛlaw dɛmɛ u ka se ka kiliyanw magow ɲɛ joona ani ka komandi caman tigɛli hakɛw ɲɛ.
