The working principle of one-to-two kudonhedzwa kunyorera vira

Iyo oparesheni modhi inotora imwe-kusvika-mbiri, imwe-kune-mbiri zvinoreva kuti seti yekugadziridza magetsi inofambisa kushanda kwemaseti maviri emagetsi emagetsi.

Shanda wakazvimiririra nechero seti ye inverter mudziyo, ipa simba kuvira A kana choto B, ine mbiri mbiri magetsi uye imwe yemabasa maviri, kunyanya.

Inokodzera hukuru-hukuru hunoenderera mberi kugadzirwa kweadiki uye epakati-saizi castings, chero yemagetsi muchoto wakakwira-simba kunyunguduka kushanda, imwe choto.

Muviri unogona kuchengetwa uchidziya kana izvo zvinotonhora zvinogona kupiswa, uye simba rinogona kugovaniswa zvisina tsarukano zvinoenderana nezvinodiwa. Simba rose remavira maviri emagetsi anogara aripo.

Ndiko kuti, simba rose P yakazara = PA + PB

Iwo maviri emagetsi emagetsi anoramba achinyunguduka uye anoramba achidziya yekukandira achimhanya panguva imwe chete, kuitira kuti magetsi agare achishanda nesimba rakazara.

Zvakanaka, kuitira kuti uvandudze kunyunguduka kwechoto chemagetsi, mufananidzo unoratidza one-to-two induction melting furnace.

Schematic dhayagiramu yeimwe-kusvika-vaviri induction yekunyungudutsa choto

Kana iyo yakatevedzana inverter magetsi ichishanda, iyo inogadziridza inogara ichishanda yakazara conduction, ichichinja inobuda simba reiyo inverter loop.

Inowanikwa nekudzora kuwanda kweiyo inverter trigger pulse. Uye iyo yazvino mutoro ndeye sine wave, saka iyo inverter simba rekupa yakabatana munhevedzano

Pachave pasina yakakwirira-yakarongeka harmonics inosvibisa zvakakomba gidhi remagetsi, uye iyo simba chinhu chakakwira. Parallel inverters haigone kuwana mumwe-ku-vaviri wega

Dynamic simba rekugadzirisa mashandiro, nekuti kugadziridzwa kwesimba kweparallel inverter magetsi kunogona kuwanikwa chete nekugadzirisa inobuda voltage yebhiriji rectifier.

Kana iyo inverter rectifier bhiriji ichishanda pane yakaderera voltage uye yekudzoreredza conduction angle idiki kwazvo, iyo simba chinhu chemidziyo ichave yakaderera zvakanyanya.

Uye iyo parallel inverter load current is square wave, iyo inosvibisa zvakanyanya grid. Kana simba racho richigadziriswa nekugadzirisa inverter back pressure angle,

Iro simba rekugadzirisa renji rakatetepa, saka parallel inverter magetsi emagetsi haakwanise kuwana imwe-drive-mbiri kushanda.
