Maitiro ekusarudza Iyezvino yeDual Power Transfer switch

Muchigadziro chemagetsi maviri ekushandura simba, inonyanya kukosha ndeyezvino control module (TCM), nokuti ikozvino haina kusimba zvakakwana kuti iite zvose zvinodiwa.

Pese pese pekupinda nekubuda kunopera pane resistor ine basa rekudzikamisa ikozvino kune yakatarwa renji.Iyi resistor inowanzonzi yazvino yekumisikidza resistor (LOR) kana yazvino yekumisikidza unit (LOC) kana yazvino yekumisikidza unit (LU), uye inoshandiswa kudzora kubuda kwazvino.

Iyo yakajairika mbiri mbiri yekuchinjisa magetsi ine maviri magetsi emagetsi.

Imwe ndiyo chubhu inobuda, iyo inodzora ku-off kweimwe MOSFET, uye imwe yacho ichubhu yekupinda, iyo inodzora imwe transistor iri kunze-kure.

Yazvino-inomisa sedunhu inodiwa kuti machubhu ese ari maviri avhure uye avharwe panguva imwe chete uye kuti MOSFET ishande pazasi penzvimbo yekuvharwa.

Iyi ndiyo musimboti wakakosha uye mashandisiro eiyo mbiri magetsi ekufambisa switch.

Muchishandiso chinoshanda, isu tinofanirwa kutarisisa kune yayo yekushanda nharaunda uye zvinodiwa, senge tembiricha yekushanda, mutoro, voltage level, frequency uye mamwe ma paramita anosangana nezvinodiwa zvekugadzira.

Kutanga, patinoshandisa dhizaini yemagetsi maviri, tinofanira kutarisisa kuhukuru hwemutoro wekusarudza ikozvino.

Panguva imwecheteyo, kana mutoro uri mukuru ikozvino, zvino zvakakosha kusarudza ikozvino yakakodzera kuti isangane nezvinodiwa zvemazuva ano makuru.

Muzhinji, mumagetsi ekupinza akaenzana nemagetsi ekubuda uye kuramba kwemutoro, kukura kwemutoro, kunowedzera kunoenderana ikozvino.

Kune zvimwe zvidiki zvemagetsi zvigadzirwa zvemagetsi zvakaita senharembozha, mashandisirwo emagetsi anofanirwa kuverengerwa uye bhatiri harifanirwe kushandiswa rakakura zvakanyanya.

Zviviri, zvemutoro mudiki, senge nharembozha bhatiri (kuchaja), komputa inotakura (simba remagetsi) mutoro mudiki wakadaro, kana iri mbozha nhare yekuchaja, isu tinofanirwa kufunga nezvesarudzo yemazuva ano yakakodzera pasina kukanganisa basa rakajairika rebhatiri. .

Kana iri komputa inogashira magetsi, mukusarudza yenguva yekufunga yakayerwa simba remugadziri.

Izvi zvine chekuita nehuwandu hwebhatiri redu.

Nokuti ikozvino yakakura, saka kurasikirwa kwemazuva ano kwakakura, simba rekubuda richaderedzwa maererano;Panguva imwecheteyo, yakakura kubuda ikozvino inorevawo kupisa kwakawanda, kudiwa kwesimba repamusoro uye kuwedzera mari yehurongwa.

Saka mukusarudza kwehuviri simba switch inofanirwa kufunga nezve yazvino, switching frequency, input voltage uye zvimwe zvinhu.

Yetatu, yemutoro wakakura, senge komputa mamaboard, giraidhi kadhi, CPU yakadai yakakwira-simba rekuburitsa midziyo, kuitira kuti ive nechokwadi chekuti michina munguva refu isingapindirwe magetsi inoramba ichishanda, zvinokurudzirwa kusarudza yakakodzera. current;

Kana simba remidziyo isiri yakakura, iwe unogona kushandisa diki yakabuda ikozvino, iyo isingagone chete kugadzikana kwedunhu munguva yakareba yekuenderera mberi kwemagetsi, asi zvakare inoderedza kukanganisa pane zvinobuda zvikamu.

Kana iyo dhizaini isingatarise sisitimu iri munzvimbo isingapindirwe magetsi ekushandisa kuti ishande zvakajairika uye inoda kushanda kazhinji, unogona kusarudza yakakura ikozvino mbiri mbiri simba switch.

Paunenge uchishandisa maviri maviri emagetsi switch, ita shuwa yekuteerera kune anotevera mapoinzi:

1. Dual simba switch iri nani kushandisa tembiricha yekudzivirira modhi;2. Iva nechokwadi chokuti magetsi anogara ari mukati mehutano hwakachengeteka panguva yekushandiswa;3. Edza kushandisa hombe ikozvino kaviri simba chinja, inogona kuvandudza redunhu kugadzikana kuita;4. Muchigadziro, edza kufunga nezvekugara kwenguva refu kwemagetsi uye kuenderera mberi kwemagetsi kudiwa kwemutoro unobuda, uye funga kugadzikana kwayo.

Chechina, Kana isu tichida kupa simba kumidziyo kana mamwe mitoro mikuru:

· Kana magetsi maviri achidiwa, magetsi maviri emagetsi ane simba pakati pemagetsi maviri ari 1.5 times the rated value, kana kuti yakarongerwa ikozvino kuve 100A, kana kuti yakarongwa ikozvino kuve 2 nguva ichasarudzwa.

· Simba remagetsi rine simba guru uye rakaderera remedu rekudzivirira rinofanira kusarudzwa kana yakakura ikozvino inoda kupiwa.

· Kana tichida kuisa magetsi ezvimwe midziyo, tinofanira kushandisa magetsi maviri.

shanu, kana isu tisina zvakanyanya zvinodiwa pamamiriro ekushanda emidziyo.

Kana zvinodiwa zvechigadzirwa zvakaderera zvakanyanya, se <50A ikozvino, <1A inobuda simba.

Kuti udzivise kuwandisa (senge yakakwira zvakanyanya), kazhinji kana simba rekubuda riri diki kwazvo, harigone kushandisa hombe iripo kana voltage.

Isu tinogona chete kushandisa maviri maviri emagetsi switch uye ikozvino inomisa resistor ine yakakwira yakayerwa ikozvino kuti isangane nezvinodiwa.

Kana iyo yakayerwa ikozvino iri diki, unogona kushandisa yakakura ikozvino yehuviri simba switch.
