HordhacBeddelaha
Inverter waa qalab elektaroonik ah oo u beddela koronto beddela koronto toos ah, oo inta badan loo isticmaalo in lagu siiyo koronto culays ah. Inverter waa qalab u beddela isha danabka DC isha danabka AC. Waxaa loo isticmaali karaa nidaamka kombiyuutarrada yar yar ama kuwa hal-jajab ah iyo sidoo kale qalabka farsamaynta calaamadaha.
Beddelayaashawaxaa loo qaybin karaa inverters hal-waji, saddex-waji iyo saddex-waji oo buundo buuxda ah iyadoo loo eegayo heerka awoodda. Inverters hal-waji iyo saddex-waji ah waxay ka kooban yihiin transformers, filtarrada iyo shaandheeyayaasha LC, qaabka hirarka soo-saarkuna waa hirarka sine; inverters-ka buundada oo dhan waxay ka kooban yihiin wareegga shaandhada hagaajiyaha, wareegga Schottky diode (PWM) iyo wareegga wadista, qaabka hirarka soo-saarkuna waa hirar laba jibbaaran.
Beddelayaashawaxaa loo kala saari karaa saddex nooc: nooca go'an ee ku-meel-gaadhka ah, nooca xakamaynta aagga dhintay (marinka hirarka sine) iyo nooca xakamaynta badhanka (marinka hirarka laba jibbaaran). Iyadoo la horumarinayo tignoolajiyada korontada korontada, qalabka korontada ku shaqeeya ayaa si weyn loogu isticmaalaa meelo kala duwan.
Fikradaha aasaasiga ah
Qalabka korontada ku shaqeeya waa qalab koronto oo awood leh kaas oo korontada tooska ah u beddela koronto beddelan. Qalabka korontada ku shaqeeya wuxuu ka kooban yahay wareegga shaandhada hagaajiyaha, wareegga Schottky diode (SOK) iyo wareegga wadista.
Qalabka korontada ku shaqeeya waxaa loo qaybin karaa inverter firfircoon iyo inverter dadban, inverter dadban, oo sidoo kale loo yaqaan wareegga inverter ama wareegga nidaamiyaha danabka, guud ahaan marxaladda gelinta, shaandhada marxaladda dhexe (LC), marxaladda wax soo saarka (hagaajiyaha), iwm., inverter-ka firfircoonina waa beddelka calaamadda danabka gelinta si loo helo danab DC oo deggan.
Beddelaha aan firfircoonayn badanaa wuxuu leeyahay capacitor magdhow ah oo ku jira buundada hagaajiyaha, halka beddelaha firfircoon uu leeyahay inductor shaandheyn ah oo ku jira buundada hagaajiyaha.
Wareegga inverter-ka wuxuu leeyahay faa'iidooyin cabbir yar, miisaan fudud, hufnaan sare iyo wixii la mid ah. Waa qaybta ugu muhiimsan dhammaan noocyada qalabka elektaroonigga ah ee awoodda leh.
Kala-soocidda
Sida laga soo xigtay qaab-dhismeedka inverter-ka, waxaa loo qaybin karaa: inverter-buuxa ah, inverter-jiid riix ah.
Waxaa loo qaybin karaa inverter-ka PWM (modulation width modulation), inverter-ka SPWM (quadrature signal modulation) iyo inverter-ka SVPWM (space voltage vector modulation).
Sida laga soo xigtay kala soocidda wareegga wadista waxaa loo qaybin karaa: nooca buundada badhkeed, nooca riix-jiidashada.
Sida ku cad nooca culayska, waxaa loo qaybin karaa korontada hal-waji ee inverter-ka, korontada saddex-waji ee inverter-ka, qalabka DC-ga, korontada inverter-ka firfircoon ee filter-ka, iwm.
Sida laga soo xigtay habka xakamaynta waxaa loo qaybin karaa: qaabka hadda jira iyo qaabka danab.
Goobta Codsiga
Inverters-ka waxaa si weyn loogu isticmaalaa otomaatiga warshadaha, qalabka militariga, hawada sare iyo meelaha kale. Tusaale ahaan, otomaatiga warshadaha, aaladaha magdhowga korontada ee falcelinta leh ee inta badan loo isticmaalo nidaamyada korontada waxay hagaajin karaan sahayda korontada ee danab sare leh, waxay hagaajin karaan hufnaanta wax soo saarka, waxay badbaadin karaan tamarta korontada waxayna bixin karaan sahay koronto oo deggan wax soo saarka warshadaha; isgaarsiinta, aaladaha magdhowga korontada ee falcelinta leh waxaa loo isticmaali karaa in lagu hagaajiyo danabka nidaamyada danab hooseeya si loo xasiliyo meel macquul ah oo loo gaaro isgaarsiinta masaafada dheer; gaadiidka, waxaa loo isticmaali karaa nidaamka bilowga matoorka baabuurta iyo nidaamka dallacaadda baytariga baabuurta; qalabka militariga, waxaa loo isticmaali karaa nidaamka xakamaynta otomaatiga ah ee qalabka hubka; hawada sare, waxaa loo isticmaali karaa sahayda korontada ee bilowga matoorka diyaaradaha iyo sahayda korontada ee dallacaadda baytariga.
