Handizive kana wawana dambudziko, MOSFET inoita senge inoshandura magetsi ekushandisa panguva yekushanda dzimwe nguva kupisa kwakanyanya, kuda kugadzirisa dambudziko rekupisaMOSFET, chokutanga tinoda kuona kuti chii chinokonzera, saka tinofanira kuongorora, kuti tizive kuti dambudziko riri papi. Kuburikidza nekuwanikwa kweMOS kupisa dambudziko, enda kukusarudza yakakodzera kiyi bvunzo bvunzo, haienderane nekuongorora, iyo ndiyo kiyi yekugadzirisa dambudziko.
Mukuedzwa kwemagetsi, pamusoro pekuyera dunhu rekutonga remamwe maturusi epini voltage inorema, inoteverwa neoscilloscope kuyera yakakodzera voltage waveform. Kana isu tichienda kunoona kana magetsi ekuchinja asiri kushanda nemazvo, kupi kuyera magetsi anogona kuratidza mamiriro ekushanda haasi akajairwa, PWM controller inobuda haina kujairika, iyo pulse duty cycle uye amplitude haina kujairika, kushandura MOSFET ndiko. kusashanda nemazvo, kusanganisira iyo transformer yechipiri uye yekutanga divi uye kubuda kwemhinduro hakuna musoro.
Kunyangwe nzvimbo yekuyedza isarudzo ine musoro yakakosha, sarudzo chaiyo inogona kuve yakachengeteka uye yakavimbika zviyero, asi zvakare inotibvumira kukurumidza kugadzirisa dambudziko kuti tizive chikonzero.
Kazhinji chikonzero chekudziya kweMOSFET ndechekuti:
1: G-pole drive voltage haina kukwana.
2: Iyo Id ikozvino kuburikidza nedhiraini uye sosi yakakwira zvakanyanya.
3: Mafambiro ekutyaira akawandisa.
Saka kutarisisa kwebvunzo muMOSFET, kuyedza basa rayo, rinova iro mudzi wedambudziko.
Zvinofanira kucherechedzwa kuti kana tichida kushandisa oscilloscope bvunzo, isu tinofanirwa kutarisisa zvakanyanya kuwedzera zvishoma nezvishoma mumagetsi ekuisa, kana tikaona kuti peak voltage kana ikozvino inodarika dhizaini yedu, panguva ino tinofanira kutarisisa. kudziya kweMOSFET, kana paine kusanzwisisika, iwe unofanirwa kudzima magetsi, kugadzirisa dambudziko pane dambudziko, kudzivirira kuti MOSFET isakuvadzwe.
