Mphamvu zamagetsi monga zida zogawa zida zamagetsi, kuphatikiza pamikhalidwe yoganizira zomwe zidaperekedwa ndi zida zamagetsi, njira zake zodzitetezera ndizambiri.zofunika, monga kupitirira panopa, kuwonjezereka kwamagetsi, kukonza kutentha kwambiri. Mphamvu yamagetsi ikapanda kukhala ndi pulogalamu yodzitchinjiriza yodzitchinjiriza, kulephera kwafupikitsa kapena kuchulukira kungayambitse kuwonongeka kwa magetsi, komanso mwina kungayambitsenso.chiwonongeko zida zamagetsi, ndipo ngakhale kuchititsa ntchito yeniyeni ya ndodo ya ngozi electrocution ndi moto ndi ngozi zina chitetezo, ndi overcurrent chitetezo cha magetsi ndi ntchitoZithunzi za MOSFET zokhudzana.
Kunena mosapita m'mbali chitetezo overcurrent, ndi linanena bungwe la yochepa dera zolakwika kapena zimamuchulukira pa magetsi kapena katundu kukonza, pa siteji iyi ya magetsi overcurrent chitetezo pali njira zosiyanasiyana, monga nthawi zonse-panopa, nthawi zonse linanena bungwe. mtundu mphamvu, etc., koma chitukuko cha overcurrent dera chitetezo sangathe kulekana ndi MOSFET, ndi MOSFETs apamwamba akhoza kusintha udindo wa magetsi overcurrent chitetezo.
