Sarudza iyo chaiyo MOSFET yemutyairi wedunhu chikamu chakakosha cheiyoMOSFET kusarudzwa hakuna kunaka kuchakanganisa zvakananga kushanda kwedunhu rose uye mutengo wedambudziko, zvinotevera tinoti inonzwisisika kona yekusarudzwa kweMOSFET.
1, N-channel uye P-channel kusarudzwa
(1), Mumaseketi akajairwa, kana MOSFET yakadzikwa uye mutoro wakabatana netrunk voltage, MOSFET inoita yakaderera voltage side switch. Mune yakaderera voltage side switch, N-channel MOSFET inofanirwa kushandiswa, nekuda kwekufunga nezve voltage inodiwa kudzima kana kubatidza mudziyo.
(2), kana MOSFET yakabatana nebhazi uye mutoro wakadzimwa, yakakwira voltage side switch inofanirwa kushandiswa. P-channelMOSFETs anowanzo shandiswa mune iyi topology, zvakare kune voltage drive kufunga.
2, vanoda kusarudza zvakanakaMOSFET, zvinodikanwa kuona iyo voltage inodiwa kutyaira chiyero chevoltage, pamwe nekugadzirwa kweiyo nzira iri nyore yekushandisa. Kana iyo yakayerwa voltage yakakura, mudziyo unozongoda mutengo wakakwira. Kune anotakurika dhizaini, yakaderera voltages yakajairika, nepo kune maindasitiri dhizaini, yakakwirira voltages inodiwa. Nekureva nezvechiitiko chinoshanda, iyo yakatemerwa voltage inoda kuve yakakura kupfuura trunk kana bhazi voltage. Izvi zvinopa chengetedzo yakakwana kuitira kuti MOSFET isakundikane.
3, inoteverwa nekugadzirwa kwedunhu, chiyero chemazuva ano chinofanira kunge chiri chepamusoro chezvino icho mutoro unogona kumira pasi pemamiriro ezvinhu ose, iyo inobvawo pamusoro pekuchengetedzwa kwezvinhu zvinodiwa kufunga.
4. Pakupedzisira, kushandiswa kwekushandura kweMOSFET kunotsanangurwa. Kune akawanda ma paramita anokanganisa kushandura mashandiro, asi akanyanya kukosha igedhi / dhiraini, gedhi / sosi uye dhiraivha / sosi capacitance. Aya macapacitance anogadzira kurasikirwa kwekuchinja mumudziyo nekuti anofanirwa kubhadhariswa panguva yega yega switch.
