Magetsi inverters, sezvikamu zvepakati mumunda wemagetsi emagetsi, anoshandiswa zvakanyanya mumashandisirwo akadai semagetsi ekugadzira photovoltaic, mota dzemagetsi, uye asingapindiki magetsi emagetsi (UPS). Magadzirirwo avo ekugadzira anokanganisa zvakananga kutendeuka kushanda zvakanaka uye kuvimbika. Kune nyanzvi dzekutengeserana dzekunze, kunzwisisa iyo yakakosha chimiro cheinverters kunobatsira kuzadzisa zvinodiwa nevatengi uye nekuvandudza tekinoroji yekutaurirana.
Iyo core structure ye inverter inogona kukamurwa kuita mamodules makuru mashanu: input circuit, DC{{0}DC converter, inverter bridge, output filtering, and control system. Iyo yekupinda seketi ine basa rekudzikamisa iyo yekuisa yeDC simba (senge mabhatiri kana photovoltaic mapaneru) uye inowanzo sanganisira EMI mafirita uye surge dziviriro zvishandiso kuti ive nechokwadi chekuchena kwesimba rekuisa. DC-DC converter (kana zvichidiwa) inogadzirisa voltage level kuti ienderane nezvinodiwa padanho rinotevera reinverter.
Bhiriji reinverter ndiyo "moyo" yeinoshandura, inoumbwa nemagetsi ekuchinja magetsi akadai seMOSFETs nemaIGBT, anoshandura magetsi eDC kuita AC kuburikidza ne-frequency switching. Matauriro akajairika anosanganisira hafu{{2}zambuko, yakazara{{3}zambuko, nenhatu-zambuko. Paunenge uchisarudza ma inverters ekutengeserana nedzimwe nyika, zvakakosha kuti usarudze mhinduro chaiyo zvichienderana nemusika unotarirwa iwo voltage zviyero (semuenzaniso, 220V/50Hz kana 110V/60Hz).
Sefa inobuda inobvisa-frequency harmonics uchishandisa inductors nemacapacitor, zvichiita kuti simba reAC rinobuda rive pedyo nesine wave. Izvi zvakakosha pazviridzwa kana grid-zvakabatana. Chekupedzisira, iyo control system (kazhinji yakavakirwa paDSP kana MCU) inogadzirisa frequency, chikamu, uye voltage munguva chaiyo kuti ive nechokwadi chekubuda kwakadzikama, uye inobatanidza zvinhu zvekudzivirira zvakaita sekuwandisa kwemhepo, overcurrent, uye pfupi{4}}kuchengetedzwa kwedunhu.
Kubva pamaonero ekutengeserana epasi rese, inverter chimiro chinodiwa zvinosiyana zvakanyanya pamisika: vatengi vekuEurope neAmerica vanoisa pamberi pekuita kwepamusoro uye kutevedzera zvitupa (semuenzaniso, UL neEC), nepo misika iri kusimukira inogona kukoshesa mutengo uye kusimba. Kunzwisisa zvimiro izvi kunogona kubatsira vatengesi kukurumidza kusangana nezvinodiwa nevatengi uye kuvandudza mitengo yekushandura odha.
