Kuongorora uye Kusarudzwa kweSimba Rekugadzirisa Scheme ye Induction Kuchenesa Vira

Sezvo panguva yekupisa yekupisa, iyo inorema yakaenzana ma paramita ichachinja nekudziya uye kunyunguduka kwechaji uye inodziya nzira inodiwa, iyo induction yekudziya magetsi magetsi inofanirwa kukwanisa kugadzirisa simba remutoro. Sezvo akateedzana resonant inverters aine akawanda akasiyana maitiro ekugadzirisa simba, isu tinofanirwa kuita sarudzo dzine musoro mukuita kwekusimudzira zvinoenderana nemashandisirwo chaiwo uye kuita zvinodiwa.

Iyo magetsi ekugadzirisa maitiro eiyo system anogona kazhinji kukamurwa kuita marudzi maviri: DC padivi simba rekugadzirisa uye inverter side simba kugadzirisa.

Iyo DC yedivi simba regulation ndeyekugadzirisa simba rinobuda reiyo inverter nekugadzirisa amplitude yemagetsi ekupinza eiyo inverter link paDC simba redivi reiyo inverter, kureva, iyo voltage regulation simba regulation mode (PAM). Nenzira iyi, mutoro unogona kushandiswa pa resonance kana kushanda frequency padyo neresonance kuburikidza nechikamu-yekuvhara matanho.

Pane nzira mbiri dzekugadzirisa magetsi ekubuda kweiyo induction yekupisa choto: chikamu-chinodzorwa kugadzirisa kana kusingadzoreki kugadzirisa kunoteverwa nekucheka.

Inverter yedivi simba regulation ndeye kushandura inobuda inoshanda mamiriro eiyo inverter nekudzora kushandura maitiro emagetsi emagetsi eiyo inverter link muyero inverter, kuitira kuti uone mutemo wekubuda kwesimba reiyo inverter.

Iyo inverter padivi simba modulation inogona kukamurwa kuita pulse frequency modulation (PFM), pulse density modulation (PDM), uye pulse phase shift modulation. Kana iyo inverter yedivi remagetsi gadziriso chirongwa chakagamuchirwa, kusingadzoreki kugadzirisa kunogona kushandiswa padivi reDC, iyo inorerutsa iyo yekudzoreredza induction yekudziya yevira uye inovandudza iyo yakazara grid-parutivi simba chinhu. Panguva imwecheteyo, kumhanya kwekupindura kweiyo inverter side simba rekugadzirisa inokurumidza kupfuura iyo yedivi reDC.

Iyo chikamu-inodzorwa kugadzirisa uye simba kugadzirisa induction yekupisa choto iri nyore uye yakakura, uye kutonga kuri nyore; kushanda uye kuvimbika kwesimba rekugadzirisa simba rekugadzirisa simba rechopper richaderedzwa mumamiriro epamusoro-simba, uye harina kukodzera kushandiswa kwemaitiro emagetsi. Pulse frequency modulation ichave nepesvedzero huru pane yekudziya workpiece nekuda kwekuchinja kweiyo frequency panguva yekugadzirisa simba maitiro; pulse density modulation ine kushomeka kwekushanda musimba rakavharwa loop nguva, uye inopa yakatsikwa nzira yekugadzirisa simba; pulse phase shift shift power adjustment will Kuwedzera kurasikirwa kwesimba, sekushandiswa kwezvinyoro zvinyoro, kuchawedzera kuoma kweiyo induction inopisa vira.

Kubatanidza zvakanakira nekuipira kweidzi nzira shanu dzekugadzirisa simba, dzakasanganiswa nebasa reiyi nyaya mune yakakwirira-simba mamiriro, sarudza kushandisa thyristor phase-inodzorwa gadziriso yekugadzirisa simba, uye tora inoshanduka DC inobuda voltage supply inverter link nekugadzirisa thyristor conduction angle. Nekudaro kushandura simba rekubuda reiyo inverter link. Iri rudzi rwesimba rekugadzirisa nzira ye induction yekupisa choto iri nyore uye yakakura, uye kutonga kuri nyore.
