Dhizaini yePCB yeBridge Rectifier yeKupisa uye Nzira dzeKushanduka Kwemazuva

Zvigadziriso zvemabhiriji zvinhu zvakakosha munyika yezvemagetsi, zvichishanda sekiyi yekushandura alternating current (AC) kuita stable direct current (DC). Nekushandisa kunosanganisira magetsi, machaja emabhatiri, uye zvishandiso zvakasiyana-siyana zvemagetsi, kunzwisisa kuoma kwekugadzira bridge rectifier PCB kwakakosha. Chinyorwa chino chinoongorora zvakadzama dhizaini yePCB rectifier yebhiriji , ichifukidza zvese kubva pazviri nyore kusvika pamaitiro epamusoro-soro, ichikupa ruzivo rwekugadzira marongero ePCB anoshanda uye akavimbika.

Peji rino nderesarudzo dzemagadzirirwo ebhodhi mushure mekunge topology ye rectifier yasarudzwa. Kuti uwane tsananguro huru yedunhu, tanga ne bridge rectifier basics ; kana basa riripo riri rekuisa uye kuronga, enzanisa cheki negwara rakazara re rectifier layout.

Bridge Rectifier Basics

Chii chinonzi Bridge Rectifier?

A bridge rectifier idunhu remagetsi rinoshandura AC voltage kuita DC voltage. Inoshanda seyakazara-wave rectifier, ichishandisa mana diode akagadziridzwa muhurongwa hwebhiriji kushandura AC kuita DC. Kubuda kwebhiriji rectifier ndeye pulsating DC voltage, iyo inogona kukwenenzverwa kunze uchishandisa capacitor sefa.

Sei Uchishandisa Bridge Rectifier muPCB Dhizaini?

Mabhiriji anogadziridza anowana kushandiswa kwakajairwa muPCB dhizaini nekuda kwekureruka kwavo, kushanda nesimba, uye kuita-mutengo. Ivo vanounza yakagadzikana uye yakavimbika sosi yeDC simba, ichiita kuti ive yakakodzera kune dzakasiyana siyana dzemagetsi zvigadzirwa. Kureruka kwavo kwekubatanidzwa muPCB marongero kunowedzera kusimbisa nzvimbo yavo sesarudzo inosarudzika kune akawanda maapplication.

Zvikamu zveBridge Rectifier

Izvo zvakakosha zvikamu zvebhiriji rectifier zvinosanganisira mana diode, inoremedza resistor, uye capacitor sefa. Iwo madhiodhi akarongedzerwa mukugadzirisa bhiriji, aine madhiodhi maviri munhevedzano uye anoenderana nemamwe maviri diode. Inoremerwa inodzivirira yakabatana munhevedzano neinobuditsa kudzikamisa kuyerera kwazvino, uye capacitor sefa inotsvedzerera iyo inopuruzira DC voltage inogadzirwa neinogadzirisa.

Muchidimbu, mabhiriji anogadziridza anoita basa rakakosha muPCB dhizaini, ichipa yakatwasuka uye inoshanda nzira yekushandura AC kuita DC. Kureruka kwavo, kushanda nesimba, uye kudhura-zvinobudirira kunoita kuti vave sarudzo yekufambisa magetsi akasiyana siyana.

Dhizaini Mafungiro eBridge Rectifiers

Paunenge uchitanga dhizaini yekugadziridza bhiriji PCB, zvakati wandei zvakakosha zvinofanirwa kuchengetwa mupfungwa. Izvi zvinosanganisira voltage uye zvazvino ratings, thermal management, uye PCB dhizaini dhizaini.

Voltage uye Current Ratings

Kunyatsoongorora mavheti uye zviyero zvazvino zvebhiriji rectifier kwakakosha kuti ive nechokwadi chekuti inokwanisa kubata zvinodikanwa zvesimba redunhu. Chiyero chevoltage chinofanirwa kudarika peak voltage yeiyo AC yekupinza, nepo chiyero chazvino chinofanirwa kuenderana neredhiyo yakanyanya kudhirowa ikozvino.

Thermal Kufunga

Bridge rectifiers inogona kuunza kupisa kwakanyanya panguva yekushanda, zvichiita kuti kutonga kwemafuta kuve kwakakosha kune redunhu rehupenyu uye kuvimbika. Kusarudza heatsink yakakodzera, kufunga nezvekupisa kwekushisa, uye kugadzirisa saizi yeheatsink uye kuiswa matanho akakosha ekubvisa kupisa zvinobudirira.

PCB Layout Dhizaini Mafungiro

Iyo dhizaini yePCB inoita basa rakakosha mukuita kwebhiriji rectifier wedunhu. Mafungiro akakosha anosanganisira:

• Trace Width: Sarudza trace wides inokwanisa kubata iyo yakanyanya ikozvino iyo dunhu richadhirowa.
• Trace Spacing: Ita shuwa kuti pave nenzvimbo yakaringana pakati pemateki kudzivirira kusungirira uye kuchengetedza kwakaringana insulation.
• Component Placement: Isa zvikamu zvine hungwaru kuti uderedze kureba kwekutevera uye kuderedza kupindira.
• Ndege yepasi: Kushandisa ndege yepasi kunogona kubatsira kuderedza ruzha uye kuwedzera kushanda kwedunhu.

Muchidimbu, kunyatsotarisisa kumagetsi uye zviyero zvazvino, manejimendi ekupisa, uye PCB dhizaini yakakosha pakuvimbika uye hupenyu hurefu hwebhiriji rectifier PCB.

Bridge Rectifier PCB Layout Dhizaini Maitirwo

Schematic Design

Nhanho yekutanga mukugadzira bhiriji rectifier PCB dhizaini kugadzira yakazara schematic dhizaini. Iri dhayagiramu rinodonongodza kubatanidza kwemagetsi pakati pezvikamu zvakasiyana-siyana zvedunhu. Kuve nechokwadi chekuti schematic ndeyechokwadi uye kukwana kwakakosha usati waenderera mberi.

Component Placement

Mushure mekupedzisa hurongwa, nhanho inotevera ndeyekuiswa kwechikamu pane PCB marongero. Kuiswa kwechikamu kunokanganisa zvakanyanya mashandiro edunhu, tichifunga nezvezvinhu zvakaita sekuyerera kwechiratidzo, kupisa kupisa, uye saizi yechikamu.

Kuti uite zvakakwana, zvinokurudzirwa kuisa diode pedyo ne transformer sezvinobvira. Izvi zvinoderedza kureba kwekutsvaga, kuderedza njodzi yeruzha uye kukanganisa.

hwokutiparadza

Kana zvikamu zvave panzvimbo, chikamu chinotevera chinosanganisira nzira dzekufambisa pakati pazvo. Kutsvaga kwakakodzera kwakakosha kuderedza ruzha uye kukanganisa. Izvi zvinogona kuwanikwa kuburikidza nekushandisa nzira dzakaita sekushandisa ndege yepasi, kuisa pamberi-yepamusoro-frequency chiratidzo chekufambisa, uye kudzivirira makona akapinza.

Izvo zvakakoshawo kuve nechokwadi chekuti trace wides inokwana kugarisa ikozvino inoyerera kuburikidza navo. Kuverengera hupamhi hwekutsvagisa hunogona kuitwa uchishandisa fomula: I = dT / (0.048 x A), pandinomiririra ikozvino mumaamps, dT ndiyo tembiricha inokwira mumadhigirii Celsius, uye A ndiyo nzvimbo yepakati-chikamu cheiyo trace mumasquare mils. .

Nekuomerera kumatanho aya, yakanyatsogadzirwa bhiriji rectifier PCB dhizaini inogona kuwanikwa, yakagadziridzwa kuita zvese uye kuvimbika.

Kuedza uye Kugadzirisa Bridge Rectifier PCBs

Kuedza Kuita

Usati waisa PCB yekugadziridza bhiriji pakuyedzwa, zvakakosha kuti uone kuti zvese zvikamu zvakaiswa nemazvo uye kutengeswa. Kana izvi zvangosimbiswa, nzira inotevera yekuyedza inogona kushandiswa:

1. Isa multimeter kune diode test mode.
2. Batanidza probe dzvuku kune yakanaka terminal yebhiriji rectifier uye dema probe kune inegative terminal.
3. Pima kudonha kwevoltage pane imwe neimwe diode, iyo inofanirwa kudonha pakati pe0.5V kusvika 0.8V.
4. Dzosera maprobe uye kuyera kudonha kwevoltage zvakare, iyo inofanirwa kuverenga isingaperi kana yakakwirira kwazvo.
5. Dzokorora matanho 2-4 kune ese mana diode.
6. Kana madhiodhi ese akapasa bvunzo, enderera mberi nekuyedza iyo yese bhiriji rectifier wedunhu nekubatanidza iyo multimeter kune yekupinza uye yekubuda materminal. Eresa kudonha kwevoltage pane inoremerwa resistor, iyo inofanirwa kuenzana nevoltage yekupinza kubvisa kudonha kwevoltage pamadhiodhi.

Nyaya Dzakajairika

Nyaya dzinoverengeka dzakajairika dzinogona kumuka uchiyedza bhiriji rectifier PCB, kusanganisira:

• Vhura kana mapfupi diode
• Diode polarity isiriyo
• Diode overheating
• Yakawandisa voltage inodonha pama diode
• Kusakwana kwemagetsi kubuda

Matambudziko ekugadzirisa

Kana imwe yeiyi nyaya ikasangana, anotevera matipi ekugadzirisa matambudziko anogona kubatsira:

• Simbisa iyo diode polarity uye simbisa kuisirwa kwakaringana.
• Ongorora majoini emasoja uye majoini ezvese akasununguka kana anotonhora majoini ekutengesa.
• Tarisa kupinza uye kubuda mavoltages kuti uone kuti anowira mukati meiyo yakatarwa.
• Simbisa kubatanidza uye kuramba kwechibatiso chekutakura.

Kana matanho aya akasagadzirisa nyaya, zvingave zvakakosha kutsiva zvikamu zvisina kunaka kana kutsvaga rubatsiro rwenyanzvi.

mhedziso

Kugadzira bhiriji rekugadziridza PCB dhizaini inosanganisira kutarisisa kune zvakadzama uye kuomerera kune zvakanakisa maitiro. Kubva pakuongorora mavheti uye zviyero zvazvino kusvika pakuita zvinobudirira kutonga kwekupisa uye kugadzirisa PCB dhizaini, nhanho imwe neimwe inobatsira kuvimbika kwedunhu uye hupenyu hurefu.

Kugona hunyanzvi hwekugadzirisa bhiriji PCB dhizaini inopa mainjiniya simba rekushandisa mabhenefiti ekudzikama DC simba rekushandura mumaseketi emagetsi akasiyana. Kunyangwe iwe uri wekutanga kana ane ruzivo rwezvemagetsi anofarira, iri gwara rakazara rinoshongedzera iwe neruzivo uye hunyanzvi hwekugadzira inoshanda uye yakavimbika bhiriji rectifier PCB marongero.

Kana chinodiwa ichi chichikanganisa kuburitswa kwezvinyorwa kana kugadzirwa, chienzanise nekushandiswa kwezvikamu zvemagetsi uye THT usati watumira mafaira ekupedzisira kuti aongororwe.
