Misiyano Yakakosha uye Mashandisirwo
Rectifiers zvinhu zvakakosha mumaseketi akasiyana emagetsi uye magetsi ekupa masisitimu. Ivo vanoshandura alternating ikozvino (AC) kunanga ikozvino (DC), vachipa simba rinodiwa kune akawanda maturusi uye maapplication. Pakati pemhando dzakasiyana dzezvekugadzirisa, pulse rectifiers uye polarity reverse rectifiers zvinozivikanwa kune avo akasiyana maitiro uye mashandisiro. Ichi chinyorwa chinoongorora mutsauko uripo pakati peaya marudzi maviri ezvekugadzirisa, misimboti yekushanda, zvakanakira, zvakaipira, uye mashandisiro.
Pulse Rectifiers
Pulse rectifiers, inozivikanwawo semapulsed rectifiers kana controlled rectifiers, midziyo inoshandura AC kuenda kuDC nekushandisa inodzorwa semiconductor zvishandiso senge thyristors kana silicon-inodzorwa rectifiers (SCRs). Aya anogadziridza anowanzo kushandiswa mumashandisirwo anoda kunyatso kudzora pamusoro peinobuda voltage uye yazvino.
Kushanda Nheyo
Kushanda kwepulse rectifier kunosanganisira kudzora chikamu chekona yeinopinza AC voltage. Nekugadzirisa iyo inokonzeresa kona yeSCRs, iyo inobuda DC voltage inogona kudzorwa. Kana iyo SCR ikatanga, inobvumira ikozvino kupfuura kusvika iyo AC cycle yasvika zero, panguva iyo SCR inodzima. Iyi nzira inodzokorora yega yega hafu-kutenderera kweiyo AC yekupinza, ichigadzira inopuruzira DC inobuda.
Zvakanakira
Precise Control: Pulse rectifiers inopa yakanakisa kutonga pamusoro peinobuda voltage uye yazvino, ichiita kuti ive yakanakira maapplication anoda inogadziriswa DC kubuda.
Kubudirira Kwepamusoro: Aya magadzirirwo anoshanda zvakanyanya, sezvo achideredza kurasikirwa kwesimba panguva yekutendeuka.
Flexibility: Pulse rectifiers inogona kubata mitoro yakasiyana-siyana uye inokodzera mhando dzakasiyana dze AC yekupinza.
Zvakaipa
Kuoma: Kutenderera kwepulse rectifiers kwakanyanya kuomarara kupfuura izvo zviri nyore kugadzirisa, zvinoda zvimwe zvikamu zvekukonzeresa nekudzora.
Mutengo: Nekuda kwekushandiswa kweanodzorwa semiconductor zvishandiso uye mamwe maseketi ekudzora, mapurusi ekugadzirisa anowanzo kudhura.
Applications
Pulse rectifiers anoshandiswa zvakanyanya mumaindasitiri ekushandisa, kusanganisira:
1.Variable Speed Drives: Yekudzora kumhanya kwema AC motors.
2.Power Supplies: Mumagetsi akadzorwa emagetsi emidziyo yemagetsi.
3.Welding: Muchigadzirwa chewelding uko kwakakosha kutonga chaiko kwekubuda kwazvino.
4.HVDC Transmission: Mune yakakwirira-voltage yakananga ikozvino (HVDC) yekufambisa masisitimu ekuita zvakanaka
Polarity Reverse Rectifiers
Polarity reverse rectifiers, anozivikanwawo sereverse polarity protection rectifiers kana reverse voltage protection rectifiers, akagadzirirwa kuchengetedza maseketi kubva mukukuvadzwa kunokonzerwa neakaipa polarity kubatana. Ivo vanova nechokwadi chekuti dunhu rinoshanda nemazvo kunyangwe iyo polarity yemagetsi yakadzoserwa kumashure.
Kushanda Nheyo
Chinhu chikuru chepolar reverse rectifier diode kana musanganiswa wemadhidhiyo. Kana yakabatana munhevedzano nemagetsi ekupa, iyo diode inobvumira ikozvino kuyerera chete munzira kwayo. Kana iyo polarity ikadzoserwa, diode inovhara ikozvino, ichidzivirira kukanganisa kudunhu.
Mune mamwe madhizaini epamberi, maMOSFET (metal-oxide-semiconductor field-effect transistors) anoshandiswa kupa yakaderera kumberi voltage kudonha uye kugona kwepamusoro zvichienzaniswa nedhiodhi. Aya maMOSFET-based rectifiers anogadzirisa otomatiki kune chaiyo polarity uye ive nechokwadi chekushanda kwakaringana kwedunhu.
Zvakanakira
Circuit Dziviriro: Polarity reverse rectifiers zvino chengetedza zvakadzikama zvemagetsi zvikamu kubva mukukuvadzwa nekuda kwekukanganisa polarity kubatana.
Kureruka: Dhizaini iri nyore uye inogona kubatanidzwa nyore nyore mumaseketi aripo.
Kudhura-Kushanda: Diode-based polarity reverse rectifiers haidhure uye inowanikwa zviri nyore.
Zvakaipa
Voltage Drop: Diode-based rectifiers inounza kudonha kwemagetsi kumberi, izvo zvinogona kuderedza kushanda kwese kwedunhu.
Kudzora Kwakaganhurirwa: Aya anogadziridza haape hutongi pamusoro peinobuda voltage kana yazvino, sezvo basa ravo rekutanga kuchengetedzwa.
Applications
Polarity reverse rectifiers anoshandiswa mumhando dzakasiyana dzekushandisa uko kuchengetedzwa kubva kune reverse polarity kwakakosha, kusanganisira:
1.Consumer Electronics: Mumidziyo yakaita sema smartphones, malaptop, uye zvimwe zvinotakurika zvemagetsi kudzivirira kukuvadzwa kubva kune isiriyo magetsi ekubatanidza magetsi.
2.Zvemotokari: Mumagetsi emotokari kuchengetedza maseketi kubva kune reverse bhatiri kubatana.
3.Solar Power Systems: Kuve nechokwadi chekushanda kwakaringana kwesolar panels uye kudzivirira kukuvadzwa kubva kune reverse polarity.
4.Mabhatiri Machaja: Kuchengetedza maseketi ekuchaja kubva kune asiri iwo mabhatiri ekubatanidza.
Misiyano Yakakosha
Misiyano Yakakosha
Nepo ese ari maviri ekugadzirisa pulse uye polarity reverse rectifiers achitamba mabasa akakosha mumasisitimu emagetsi, mabasa awo nemashandisirwo anosiyana zvakanyanya.
