Cov khoom siv hluav taws xob raws li cov khoom siv hluav taws xob faib khoom, ntxiv rau cov yam ntxwv los txiav txim siab cov kev cai ntawm cov khoom siv hluav taws xob, nws tus kheej tiv thaiv kev ntsuas kuj tseem ceeb heev.tseem ceeb, xws li over-current, over-voltage, over-temperature care. Thaum lub hwj chim mov tsis muaj overcurrent tiv thaiv tsim kev pab cuam, nyob rau hauv cov zis ntawm short-circuit tsis ua hauj lwm los yog overload yuav ua rau kev puas tsuaj rau lub hwj chim mov, tab sis kuj yuav heev ua rau ntxiv.kev puas tsuaj ntawm cov khoom siv hluav taws xob, thiab txawm tias ua rau kev ua haujlwm tiag tiag ntawm cov neeg ua haujlwm ntawm kev sib tsoo hluav taws xob thiab hluav taws xob thiab lwm yam kev nyab xeeb, thiab kev tiv thaiv overcurrent ntawm lub hwj huam mov nrog kev sivMOSFETs ntsig txog.
Txhawm rau muab nws bluntly overcurrent tiv thaiv, yog nyob rau hauv cov zis ntawm short-circuit txhaum los yog overload ntawm lub hwj chim mov los yog load txij nkawm, nyob rau hauv no theem ntawm lub hwj chim mov overcurrent tiv thaiv muaj ntau txoj kev, xws li tsis tu ncua-tam sim no, tas li tso zis. hom fais fab, thiab lwm yam, tab sis txoj kev loj hlob ntawm xws li kev tiv thaiv overcurrent Circuit Court tsis tuaj yeem sib cais los ntawm MOSFET, MOSFETs zoo tuaj yeem txhim kho lub luag haujlwm ntawm cov khoom siv hluav taws xob. tiv thaiv overcurrent.
