Kana magetsi ari kushandiswa, anogona kunge akabatana zvisizvo kana kupfupikiswa.Mukuwedzera, iyo magetsi pachayo inogona kusashanda uye kuita kuti iyo inobuda voltage ive isina kujairika.Nokudaro, mukugadzirwa nekugadzirwa kwemagetsi emagetsi, zvinyorwa zvekuchengetedza chikamu chakakosha zvikuru.Pane mativi maviri ekudzivirira kwesimba rekupa, imwe ndeyekudzivirira zvimwe zvishongedzo kubva pakupiswa, uye imwe ndeyekuzvidzivirira kubva mukukuvadzwa.
Kudzivirirwa kwemagetsi ekunze kunonyanya kuve-over-voltage uye under-voltage protection, izvo zvinoreva kuti kana iyo inobuda voltage yemagetsi yakawandisa kana yakadzikira kuti isave yakajairika, magetsi anomira kushanda.Izvi zvakanyanya kukosha kumuchina wese, nekuti mazhinji ezvinodhura anodhura haana kusimba, uye zviri nyore kupisa kunze nekuda kwekukwira kwemagetsi.
Kuti udzivise izvi, zvinodikanwa kutarisa yega yega inobuda voltage yemagetsi.Maitiro emugadziri wemagetsi ndeyekuyedza inobuda voltage kuburikidza nesampling wedunhu, uye sampuro chiratidzo chakabatana nechikamu chekutonga kuburikidza nemuenzanisi.Kana iyo yakabuda voltage isingaite, chiratidzo chesampling chinoratidzwa nekukasira, uye chikamu chekutonga chichaziviswa kuvhara.Izvi zvinogona kudzivirira zvinobudirira zvikamu zvekubatanidza kumashure.Kunyangwe iyo magetsi ane kukurumidza overvoltage kudzivirira kwakakosha kumuchina wese.Kuti udzivise kupisa kunokonzerwa nekuwanda kwemazuva ano, magetsi anogadzirwa nefuse.
