Nhasi isu tinoongorora mashandisirwo eiyo chaiyo yedunhu basa reinductor, mudunhu chairo rinonyanya kushandiswa kwemainductors kuburikidza neakaderera-frequency kuramba kune yakakwira-frequency, kuburikidza neDC kuramba kune AC maitiro ekugadzirwa kwemasekete akasiyana, the Kutevera isu tinotarisa kune inductor muDC-DC boost circuit musimboti wekushanda.

1. Switch S yakavharwa:

Sezvinoratidzwa mumufananidzo 1, apo Switch S yakavharwa, a, b, d inoumba chivharo chakavharwa, simba rekupa E kuburikidza ne inductor rinobudisa diki kusvika kune yakakura ikozvino i, panguva ino t1 (semufananidzo 2 t1 → t2 ) ikozvino frequency inowanzova pedyo nepamusoro-frequency, maererano nemutemo we corrugator (kuwedzera anti-decrease zvakafanana), inductor inogadzira induced current inotarisana neinotarisana neyazvino yepakutanga i, induced current inotadzisa kuchinja mu iyo i, inductor yakakonzera kutungamira ikozvino kwe b → a, zvinoreva kuti simba rekupa ikozvino i mu inductor musimba remagineti rakachengetwa kusvika t2 kana yazvino ini iri hombe, simba rekuvharira ndiro rakakura zvakare, iro remagineti simba rakachengetwa. mune inductor ndiyo yakakura zvakare. Zvadaro t2 mushure mokunge ikozvino ichiita kuti iite, iyo inowanzoitika inotenderera kuDC, iyo inductor obstruction inopera simba, iyo yakawandisa ikozvino kuburikidza nekushandura, kuumbwa kwechivharo chakavharwa kunoyerera kusvika padanda risina kunaka.Unogona kuongorora zvikamu zvakafanana kubva kwatiri.All product Listkuti ishandiswe mumaseketi eDC-DC.

2. Chinja S dimbura:

Sezvinoratidzwa muMufananidzo 3, apo Switch S inobviswa, a, b, d haigadziri chivharo chakavharwa, simba rekupa E rinoyerera kuburikidza ne inductor ikozvino pakarepo kubva kune yakakura kusvika kune yakakura i, panguva ino t3 (semufananidzo 4). t3 → t4) ikozvino frequency inowanzova pedyo nepamusoro-frequency, maererano nemutemo we corrugator (wedzera anti-decrease zvakafanana), inductor inogadzira inductive current mugwara regwaro rakafanana nerekutanga ikozvino i, induced current. inondikanganisa kuchinja, kutungamira kweinductor yakakonzera ikozvino kune a → b, zvinoreva kuti simba rekushandisa Ikozvino i muinductor ichave yakashandura simba remagineti rakatanga kushandurwa kuva razvino, kutungamira kwezvino kuburikidza ne diode a → b → c → d, kureva, voltage panzvimbo b yeinductor induced electromotive force e pamwe nemagetsi ekutanga emagetsi E, ari pamwe chete kuburikidza nedhiodhi D1 kune capacitance C yekuchaja yakachengetwa, uye panguva imwe chete, kubuda. voltage kumutoro U0, kana iwe usingafungi nezvekudonha kwe diode, U0 = E + e. iyo yakakonzeresa iyo voltage inogona kuratidzwa nehukuru hweiyo A formula: Iyi fomula inoratidza kuti induced voltage saizi uye inductance saizi, chiyero chekuchinja kweazvino panguva yeyuniti inogona kuongororwa zvakare panguva yedu.New Centerzveruzivo rwehunyanzvi.

Saka panguva ino voltage U0 yakakwirira kudarika magetsi ekupa E. Kusvikira t2 apo ikozvino i idiki, simba rekudzivirira ndirowo diki, simba remagineti rakachengetwa muinductor zvakare rinonyanya kukurumidza kutendeuka kuguma. Tevere, kuburikidza neshanduko inogara yakavharwa, yakabviswa, iwe unogona kugara uchiburitsa voltage U0, uye voltage U0 yakakwira pane yekugovera voltage E, kuitira kuti utambe chinangwa chekusimudzira.
