Magetsi inverters zvigadziriso zvemagetsi zvinoshandura yakananga ikozvino (DC) kune inochinjika ikozvino (AC) uye inoita basa rakakosha muhupenyu hwazvino. Kungave mudzimba, maindasitiri, kana nharembozha, ma inverters anoshandiswa zvakanyanya kupa yakagadzikana AC simba kune akasiyana midziyo. Ichi chinyorwa chinotsanangura mabasa akakosha, misimboti yekushandisa, uye akajairwa mashandisirwo emagetsi emagetsi inverters.
Iyo Core Basa reInverter: DC kusvika AC
Basa rinonyanya kukosha reiyo inverter nderekushandura DC simba (senge simba kubva kumabhatiri kana solar panels) kuita AC simba (senge simba rinoshandiswa mudzimba kana maindasitiri). Midziyo mizhinji yemumba, maturusi emagetsi, uye midziyo yemumaindasitiri inoshanda pamagetsi eAC, ukuwo mabhatiri kana masisitimu emagetsi anovandudzwa achiwanzoburitsa magetsi eDC, zvichiita kuti inverter ive mudziyo wakakomba unobatanidza zviviri izvi.
Iyo AC magetsi ekubuda kweiyo inverter inogona kuve yakachena sine wave (yakafanana nemagetsi mains, akakodzera kune inonzwisisika michina) kana yakagadziridzwa sine wave (yakakodzera michina ine mashoma kuomesesa emhando yemhando zvinodiwa, senge mwenje mababu uye mafeni). Inverter yemhando yepamusoro{{1}inopa voltage yakagadzikana uye frequency, kuve nechokwadi kushanda kwakachengeteka uye nemazvo kwemidziyo ine magetsi.
Iyo Inverter Inoshanda sei
Musimboti wekushanda kweinoshandura kukurumidza kushandura magetsi eDC nekudzima uchishandisa magetsi switch (senge MOSFETs kana IGBTs). Simba iri rinobva raumbwa nekusefa masekete, pakupedzisira richibuditsa pedyo-sinusoidal AC simba. Maitiro makuru anobatanidzwa anosanganisira:
1.DC Input: Iyo inverter inogamuchira yakagadzikana DC simba kubva kumabhatiri, solar panels, kana mamwe DC magetsi masosi.
2. Yakakwirira-Frequency Switching: Magetsi ari mukati me inverter anobatidza nekudzima magetsi eDC nepamusoro-soro (kazhinji zviuru kusvika kumakumi emakilohertz), zvichigadzira chiratidzo cheDC.
3. Waveform Shaping: Nekudzora kuchinjisa nguva, masiginecha anopombwa anosanganiswa kuita -simba reSinusoidal AC riri pedyo.
4. Output Sefa: Sefa capacitors uye inductors anotsvedzerera yakabuda waveform, kuderedza harmonic kupindira uye kunatsiridza simba kunaka.
Mhando Dzakajairika dzeInverters
Zvichienderana neyakaburitswa waveform uye mamiriro ekushandisa, ma inverters anonyanya kuiswa muzvikamu zvinotevera:
1. Pure Sine Wave Inverter: Iyo yakabuda waveform yakafanana neiyo mains simba uye inokodzera midziyo ine simba repamusoro zvinodiwa, senge makomputa, terevhizheni, uye midziyo yekurapa.
2. Modified Sine Wave Inverter: Iyo yakabuda waveform iri pedyo neine wave, asi ine yakawanda harmonics. Inokodzera michina ine kushivirira kwakanyanya, senge magirobhu emwenje uye maturusi emagetsi.
3. Square Wave Inverter (Ishoma Yakajairika): Inoburitsa square wave. Iyo ine-mutengo wakaderera asi haina kuenderana, zvichiita kuti ikwane kune nhamba diki yemidziyo iri nyore.
Inverters inogona zvakare kuiswa muchikamu nemasimba: madiki (ashoma watts kusvika kumazana mashoma watts), yepakati (ashoma kilowatts), uye yakakura (makumi emakilowatts uye pamusoro). Aya akakodzera midziyo inotakurika, magetsi epamba, uye maindasitiri ekuchengetedza simba masisitimu, zvichiteerana.
Yakajairika Mashandisirwo eInverters
1. Simba reKumba neKunze: Panguva yekudzima kwemagetsi, inverter inogona kushandiswa nebhatiri kusimbisa midziyo yemumba. Paunenge uchidzika musasa kana kufamba muRV, inverter inogona kushandura DC simba kubva mubhatiri remotokari kuita simba reAC remidziyo midiki.
2. Solar uye Wind Power Systems: Zvitubu zvemagetsi zvinogadziriswa (zvakadai semagetsi ezuva uye mhepo turbines) zvinowanzobudisa magetsi eDC, iyo inverters inoshandura ku AC kuti ibatanidzwe mugridi kana kuti inoshandiswa kumba.
3. Industrial uye Backup Power: Mafekitori, nzvimbo dze data, uye zvimwe zvivako zvinowanzoshandisa inverters seUPSs (zvisingapindiki magetsi emagetsi) kuti zvive nechokwadi chekuenderera mberi kwekushanda kwezvinhu zvakakosha panguva yekudzima kwemagetsi.
4. Motokari dzeMagetsi uye Mabhangi Emagetsi: Inverters mumotokari yemagetsi inoshandura DC bhatiri simba ku AC kutyaira motokari; inotakurika inverters inogona kuchaja zvishandiso zvakaita semalaptop uye nharembozha.
Summary
Magetsi inverters chinhu chakakosha chemazuva ano masisitimu emagetsi. Basa ravo guru nderekushandura DC simba kuAC kuti isangane nemagetsi akasiyana siyana. Kubva pamagetsi ekuchengetedza pamba kusvika kune akakura-masisitimu emagetsi anogona kudzokororwa, mainverter anovimbisa magetsi akatsiga nekugona kwawo kushandura magetsi. Nekufambira mberi kwetekinoroji, ma inverters ari kuwedzera kushanda, akavimbika, uye akangwara, uye achaita basa rakakosha mune mamwe maapplication mune ramangwana.
