IGBT induction yekudziya magetsi emagetsi musimbi tsvimbo inodzima uye kupisa mutsara wekugadzira ine hanya zvakanyanya

Iyo simbi tsvimbo inodzima uye inodziya yekugadzira mutsara inotora IGBT magetsi maturusi uye yakasarudzika frequency yekushandura tekinoroji ine tekinoroji yepamusoro. IGBT chishandiso chinoumbwa neMOSFET uye bipolar transistor. Kupinza kwayo kwakanyanya MOSFET, uye kuburitsa kwayo kwakanyanya PNP transistor. Iyo inosanganisa zvakanakira izvi zviviri zvishandiso uye ine zvakanakira yakaderera dhiraivha simba uye nekukurumidza switching kumhanya. Iyo bipolar mudziyo ine zvakanakira kudzikisa saturation pressure uye yakakura hukuru, nekudaro inovandudza mashandiro uye kupisa kwechigadzirwa.

Iyo inobuda voltage yeakakwira-performance yepakati frequency magetsi magetsi anofanirwa kuve nekugadzikana kwakanyanya. Naizvozvo, zvinodikanwa kugadzirisa magetsi emagetsi mune yakavharwa loop kuti ichengetedze inobuda voltage isingachinji pasi pezvese zviri zviviri mutoro uye hapana-mutoro mamiriro. Iyo induction yekudziya michina inoshandisa thyristor seyakafanana resonance induction yekudziya magetsi emagetsi emagetsi, ichipa kutamba kwakazara kune super software uye hardware mabasa eiyo microcomputer. Kuburikidza nekugadziriswa kwakaringana kweiyo rectifier uye inverter, simba risingaperi (yakanyanya simba) kubuda rinogona kuwanikwa. Dunhu rekudzora rinoshandisa maviri seti e-single-chip microcomputers kudzora iyo synchronous inokonzeresa yekudzoreredza pulses uye kuitika kweinverter yekutevera frequency pulses. Iyo otomatiki yekutevera yekupedzisa frequency ine overcurrent, overvoltage, cut-off uye cut-off kuchengetedza mabasa, ayo anogona kupedzisa otomatiki yekutadza kuongororwa uye kuratidza.
