Kusiyana Kwakakosha uye Mashandisirwo
Ma rectifiers zvinhu zvakakosha muma electronic circuits akasiyana siyana uye masisitimu emagetsi. Anoshandura alternating current (AC) kuita direct current (DC), zvichipa simba rinodiwa pamidziyo yakawanda nemashandisirwo. Pakati pemhando dzakasiyana dze rectifiers, pulse rectifiers uye polarity reverse rectifiers anozivikanwa nehunhu hwawo hwakasiyana uye mashandisirwo azvo. Chinyorwa chino chinotarisa musiyano uripo pakati pemhando mbiri idzi dze rectifiers, misimboti yadzo yekushanda, zvakanakira, zvadzisina kunaka, uye mashandisirwo adzo.
Zvinogadzirisa Pulse
Mapulse rectifiers, anozivikanwawo sepulsed rectifiers kana controlled rectifiers, zvishandiso zvinoshandura AC kuita DC nekushandisa zvishandiso zve semiconductor zvinodzorwa zvakaita se thyristors kana silicon-controlled rectifiers (SCRs). Aya ma rectifiers anowanzo shandiswa mumashandisirwo anoda kudzora voltage inobuda uye current.
Nheyo yekushanda
Kushanda kwe pulse rectifier kunosanganisira kudzora phase angle ye input AC voltage. Nekugadzirisa trigger angle yeSCRs, output DC voltage inogona kudzorwa. Kana SCR yatanga, inobvumira current kupfuura nepakati kusvika AC cycle yasvika zero, ipapo SCR inodzima. Maitiro aya anodzokororwa kwehafu yega yega ye AC input, zvichigadzira pulsating DC output.
Zvakanakira
Kudzora Kwakarurama: Mapundu anogadzirisa magetsi anopa simba rakanaka pamusoro pemagetsi anobuda uye magetsi, zvichiita kuti zvive zvakanaka kune zvishandiso zvinoda DC inogadziriswa.
Kushanda Nesimba Kwazvo: Izvi zvinogadzirisa mashandiro zvinoshanda zvakanyanya, sezvo zvichideredza kurasikirwa kwesimba panguva yekushandura.
Kuchinjika: Mapundu anogadzirisa pulse anogona kubata mitoro yakasiyana-siyana uye akakodzera mhando dzakasiyana dzeAC inputs.
Zvakashata
Kuomarara: Kutenderera kwema "pulse rectifiers" kwakaoma kupfuura kwema "rectifiers" ari nyore, achida zvimwe zvikamu zvekutanga nekudzora.
Mutengo: Nekuda kwekushandisa zvishandiso zve semiconductor zvinodzorwa uye mamwe macircuit ekudzora, ma pulse rectifiers anowanzo kudhura.
Mashandisirwo
Zvinogadzirisa pulse zvinoshandiswa zvakanyanya mumaindasitiri, zvinosanganisira:
1.Madhiraivha Anochinja-chinja: Ekutonga kumhanya kwemamota eAC.
2.Zvishandiso zveMagetsi: Zviri mumagetsi anodzorwa nemutemo wezvishandiso zvemagetsi.
3.Kusonta: Mumidziyo yekusonta uko kudzora kwakarurama kwesimba rinobuda kwakakosha.
4.Kutapurirana kweHVDC: Mumasisitimu ekutapurirana kwemagetsi ane simba guru (HVDC) kuti zvishande zvakanaka
Zvigadziriso zvePolarity Reverse
Ma "polarity reverse rectifiers", anozivikanwawo se "reverse polarity protection rectifiers" kana kuti "reverse voltage protection rectifiers", akagadzirirwa kuchengetedza ma "circuit" kubva mukukuvadzwa kunokonzerwa ne "polarity connections" isiriyo. Anoita kuti circuit ishande nemazvo kunyangwe polarity yemagetsi ikadzoserwa kumashure.
Nheyo yekushanda
Chinhu chikuru che polarity reverse rectifier i diode kana musanganiswa wema diode. Kana yakabatana nemagetsi, diode inobvumira magetsi kuti afambe nenzira chaiyo chete. Kana polarity ikadzoserwa kumashure, diode inovhara magetsi, ichidzivirira kukuvara kwedunhu.
Mumagadzirirwo epamusoro-soro, maMOSFET (metal-oxide-semiconductor field-effect transistors) anoshandiswa kupa kudonha kwevoltage yakaderera uye kushanda zvakanaka zvichienzaniswa nemadiode. Aya marectifier akavakirwa paMOSFET anogadzirisa otomatiki ku polarity chaiyo uye anovimbisa kushanda zvakanaka kwecircuit.
Zvakanakira
Dziviriro yeDunhu: Magadzirirwo ePolarity reverse anodzivirira zvinobudirira zvikamu zvemagetsi zvinonzwa kubva mukukuvadzwa nekuda kwekubatana kwepolarity kusina kunaka.
Zviri Nyore: Dhizaini yacho iri nyore uye inogona kubatanidzwa zviri nyore mumaseketi aripo.
Inodhura Zvishoma: Ma diode-based polarity reverse rectifiers akachipa uye anowanikwa nyore nyore.
Zvakashata
Kudonha kweVoltage: Zvinogadzirisa magetsi zvinobva kuDiode zvinounza kudonha kwevoltage yekumberi, izvo zvinogona kuderedza kushanda zvakanaka kwecircuit yese.
Kudzora Kushoma: Izvi zvinogadzirisa magetsi hazvipe simba pamusoro pemagetsi anobuda kana magetsi, sezvo basa razvo guru riri kudzivirira.
Mashandisirwo
Mapoka ekugadzirisa polarity reverse anoshandiswa mumhando dzakasiyana dzemashandisirwo apo dziviriro kubva kupoka reverse yakakosha, kusanganisira:
1.Magetsi Emagetsi Evatengi: Mumidziyo yakaita semafoni, malaptop, nezvimwe zvemagetsi zvinotakurika kudzivirira kukuvara kubva pakubatidzwa kwemagetsi zvisiri izvo.
2.Mota: Mumotokari dzemagetsi kudzivirira maseketi kubva pakubatidzwa kwemabhatiri ekumashure.
3.Masisitimu eSimba reSolar: Kuona kuti panels dzezuva dzinoshanda zvakanaka uye kudzivirira kukuvara kunokonzerwa ne reverse polarity.
4.Macharger emabhatiri: Kuchengetedza macircuit ekuchaja kubva pakubatanidza mabhatiri zvisiri izvo.
Misiyano Yakakosha
Misiyano Yakakosha
Kunyange zvazvo zvese zvinogadzirisa pulse uye zvinogadzirisa polarity reverse zvinoita mabasa akakosha mumasisitimu emagetsi, mabasa azvo nemashandisirwo azvo zvakasiyana zvakanyanya.
Basa: Mapundu ekugadzirisa magetsi anotarisa pakushandura AC kuita DC nekudzora kwakaringana pamusoro pezvinobuda, nepo mapuru ekugadzirisa magetsi akagadzirwa kuchengetedza maseketi kubva mukukuvadzwa nekuda kwekubatana kwe polarity kusina kunaka.
Zvikamu: Mapundu ekugadzirisa mapombi anoshandisa zvishandiso zve semiconductor zvinodzorwa zvakaita seSCRs, nepo ma polarity reverse rectifiers anowanzo shandisa ma diode kana ma MOSFET.
Kuomarara: Mapundu ekugadzirisa pulse akaomarara uye anoda mamwe macircuitry ekudzora, nepo mapuru ekugadzirisa polarity reverse ane dhizaini iri nyore.
Mashandisirwo: Mapundu ekugadzirisa mapombi anoshandiswa mumaindasitiri uye mumashandisirwo ane simba guru, nepo mapombi ekugadzirisa mapombi emagetsi, mota, uye masisitimu esimba rezuva anoshandiswa zvakanyanya.
Mhedziso
Mapundu ekugadzirisa mapombi nemapundu ekugadzirisa mapombi zvinhu zvakakosha mumasisitimu emagetsi emazuva ano, chimwe nechimwe chichishanda zvakasiyana. Mapundu ekugadzirisa mapombi anopa kutonga kwakaringana uye kushanda zvakanaka mukushandurwa kweAC kuenda kuDC, zvichiita kuti akwanise kushandiswa mumaindasitiri. Kusiyana neizvi, mapundu ekugadzirisa mapombi anopa dziviriro yakakosha kubva pakusangana kwepombi zvisiri izvo, zvichiita kuti midziyo nemasisitimu akasiyana-siyana zvemagetsi zvive zvakachengeteka uye zvakavimbika. Kunzwisisa musiyano uripo pakati pemapundu aya kunobatsira mukusarudza chikamu chakakodzera chezvishandiso zvakati, zvichizopedzisira zvawedzera kushanda uye kugara kwenguva refu kwemasekete emagetsi.
