Chii Chinonzi Bhiriji Rectifier? Nheyo dzePCB neCircuit

Shandisa peji rino kuti uwane tsananguro ye core bridge rectifier. Kana dunhu rapinda muPCB layout, ongororai dhayagiramu yakazara yePCB rectifier bridge ; kuti muwane kupisa, hupamhi hwetrace, diode package, uye sarudzo dzekuunganidza, peji reruzivo rwedhizaini yePCB rectifier bridge rinofukidza ruzivo rwekugadzira.

Munzvimbo yemagetsi nehuinjiniya hwemagetsi, kushandurwa kweAlternating Current (AC) kuita Direct Current (DC) chinhu chakakosha pakusimbisa zvinhu zvakasiyana zvemagetsi nemidziyo. Mabhiriji anogadziridza anoita basa rakakosha mukuita shanduko iyi nemazvo. Ichi chinyorwa chakazara chinoongorora nyika yezvekugadzirisa mabhiriji, ichipa kunzwisisa kwakadzama kwedunhu ravo, misimboti yekushanda, uye mashandisiro.

Chinogadzirisa mabhiriji chinokanganisa hupamhi hwemhangura, kukwira kwekupisa, uye nzvimbo yekuparadzanisa, saka mabhodhi emagetsi anofanira kuongororwa zvichienderana nezvinodiwa pakurongeka kwePCB uye kusimbiswa nekuyedzwa kwemagetsi kwakakodzera usati watumirwa.

Chii chinonzi Bridge Rectifier?

A bridge rectifier chinhu chemagetsi chakagadzirirwa kushandura AC yekupinza voltage kuita yakatsetseka uye inogara DC inobuda voltage. Inoita basa iri nekushandisa gadziriso yemadhiodhi, kazhinji mana kana anopfuura, akarongwa mune chaiyo pateni. Mabhiriji anogadziridza zvinhu zvakakosha mumagetsi emagetsi, kuve nechokwadi kuti kune yakagadzikana sosi yeDC simba remhando dzakasiyana dzemagetsi ekushandisa.

Kuvakwa kweBridge Rectifier

Kuvakwa kwebhiriji rectifier kunosanganisira mana diode akarongwa muvhavha-loop pattern, kubvisa kudiwa kwepakati-tapped transformer. Iyi dhizaini haingodzikisi saizi uye mutengo chete asi inowedzera kushanda zvakanaka. Kana chiratidzo cheAC chikaiswa pamaterminal A neB, iyo DC inobuda siginecha inowanikwa pane inoremerwa resistor (RL), iyo yakabatana pakati pematerminal C neD. Madhiodhi, anoti D1, D2, D3, uye D4, maitiro. magetsi emagetsi panguva dzakasiyana siyana dze AC kutenderera. Munguva yehafu yakanaka yekufamba, D1 uye D3 mufambiro, nepo panguva yehafu yakashata, D2 uye D4 maitiro, zvichiita kuti unidirectional inoyerera yezvino.

Zvakanakira zveBridge Rectifiers

1. kunyatsoshanda: Zvigadziriso zveBridge zvinopa zvakapetwa kaviri kugadziridza kushanda zvakanaka kana zvichienzaniswa nehafu-wave rectifiers, zvichiita kuti zvive zvakanyatsoshanda mukushandura AC kuita DC.
2. Higher Output Voltage uye Simba: Bridge rectifiers inopa yakakwira yekubuda voltage uye simba, ichiita kuti ive yakakodzera kune maapplication anoda yakakura DC simba.
3. Low Ripple Voltage: Kubuda kwebhiriji rectifiers kune yakaderera ripple voltage uye yakakwirira frequency, kurerutsa kudiwa kwekuwedzera kusefa maseketi.
4. Hapana Center-Tapped Transformer: Bridge rectifiers haidi yepakati-tapped transformer, kurerutsa iyo transformer dhizaini.

Zvakaipa zveBridge Rectifiers

1. Zvinodiwa zvina Diodes: Mabhiriji ekugadzirisa anoshandisa mana diode, kuwedzera chikamu chikamu uye mutengo zvichienzaniswa nehafu-wave rectifiers.
2. Kupera Simba Kwakakwirira: Bhiriji rectifiers rinogona kunge riine simba rakawanda richienzaniswa nepakati-tapped rectifiers.

Bridge Rectifier Waveform

Iyo inobuda waveform yebhiriji rectifier inoratidzwa nekuyerera unidirectional yezvino panguva dzese dzakanaka uye dzisina kunaka hafu yeiyo AC yekupinza chiratidzo. Iyo polarity yeDC inobuda inogona kuve yakanaka zvachose kana yakaipa, zvichienderana neiyo diode kumisikidzwa. Kuwedzera kusefa, kazhinji nema capacitors, kunodiwa kuti unyorovese zvinobuda.

Bridge Rectifier Circuit Diagram

Iyo bhiriji rectifier redunhu dhizaini rine matanho akasiyana, anosanganisira transformer, diode bhiriji, kusefa, uye regulators. Uku kusanganiswa kwezvikamu kunoumba inodzorwa DC magetsi anogona kupa simba kune akasiyana siyana emagetsi midziyo.

1. Transformer: The transformer idanho-pasi mhando inoderedza amplitude yekuisa AC voltage. Mumapurojekiti mazhinji emagetsi, 230/12V transformer inoshandiswa kudzika AC mains voltage kubva pa230V kuenda ku12V AC.
2. Diode Bridge: Iyo diode bhiriji rectifier ine diode ina (D1, D2, D3, uye D4) yambotaurwa. Aya madhiodhi anoita basa rakakosha mukushandura AC kuenda kuDC nekubvumira ikozvino kuyerera munzira imwe mukati mehafu-kutenderera kwechiratidzo chekuisa.
3. mupise: Kushandura iyo pulsating DC inobuda kuita inotsvedzerera DC siginecha, imwe kana anopfuura capacitor akabatana pane inoremerwa resistor. Sarudzo ye capacitor rating inoenderana neinodiwa inobuda voltage.
4. Voltage Regulator: Muzviitiko apo chaiyo DC voltage level inodiwa, voltage regulator inoshandiswa kuchengetedza inogara ichibuda voltage. Izvi zvinogonesa kuti iyo inobuda inoramba yakagadzikana zvisinei nekusiyana kweiyo voltage yekupinza.

Kushanda Misimboti yeBridge Rectifier

Kuti unzwisise kushanda kwebhiriji rectifier, funga nezvechimwe-chikamu bhiriji rectifier rine madhiodhi mana akabatanidzwa pamutoro. Munguva yehafu yakanaka kutenderera kweiyo AC yekupinza waveform, diode D1 uye D2 inorerekera kumberi, ichibvumira iyo yazvino mutoro kuyerera nemavari. Muchikamu chakashata chehafu, diodes D3 uye D4 inova mberi yakarerekera, ichiitisa mutoro ikozvino. Muzviitiko zvese izvi, mutoro wezvino unoyerera munzira imwechete, zvichikonzera unidirectional DC ikozvino pane inobuda.

Bridge Rectifier Hunhu

1. Ripple Factor: Iyo ripple factor inoyera kutsetseka kweiyo DC inobuda chiratidzo. Kune bhiriji rectifier, ripple factor inoverengerwa se Γ = √(Vrms^2 / VDC) - 1, apo Vrms ndiyo mudzi inoreva square voltage uye VDC ndiyo DC voltage. Iyo ripple factor yebhiriji rectifier ingangoita 0.48.
2. Peak Inverse Voltage (PIV): PIV inoreva iyo yakakwira voltage inowanikwa ne diode kana iri reverse bias panguva yakashata hafu kutenderera kweiyo AC chiratidzo. Bridge rectifiers inosanganisira mana diode, uye PIV inosiyana zvichienderana.
3. kunyatsoshanda: Kushanda kwemugadzirisi ndeyereshiyo yeDC inobuda simba kune AC yekupinza simba. Mabhiriji anogadziridza anogona kuwana kugona kwakanyanya kweanosvika 81.2%.

Mhando dzeBridge Rectifiers

Bridge rectifiers inouya mumhando dzakasiyana zvichienderana nezvinhu zvakaita serudzi rwekugovera, kugona kutonga, uye kugadziridzwa kwedunhu. Ivo vanonyanya kuiswa muchikamu chimwe-chikamu uye matatu-chikamu chekugadzirisa, zvakare yakakamurwa kuva isingadzoreki, hafu-inodzorwa, uye yakazara-inodzorwa rectifiers.

Single Phase uye Three Phase Rectifiers

Single-phase bridge rectifiers anoshandisa mana diode kushandura AC to DC, nepo matatu-phase rectifiers anoshandisa diode matanhatu. Izvi zvinogadzirisa zvinogona kunge zvisingadzoreki kana kudzorwa, zvichienderana nemidziyo inoshandiswa, senge diode kana thyristors.

Uncontrolled Bridge Rectifiers

Vasingadzoreki bhiriji rectifiers vanoshandisa diode kugadzirisa inopinza, ichipa anogara kana akagadziriswa magetsi ekupa. Aya anogadziridza akakodzera maapplication uko kusiyanisa kwemagetsi kusingade.

Inodzorwa Bridge Rectifiers

Anodzorwa mabhiriji anodzoreredza anotsiva asingadzoreki diode neanodzorwa akasimba-state zvishandiso seSCR's, MOSFET's, kana IGBT's. Izvi zvinobvumira kusiyanisa simba rekubuda pamagetsi akasiyana nekukonzeresa zvishandiso izvi panguva dzakasiyana siyana.

Zvishandiso zveBridge Rectifiers

Mabhiriji anogadziridza anowana mashandisirwo akapararira mumagetsi uye engineering yemagetsi nekuda kwekushanda kwavo uye kuvimbika. Mamwe maapplication akajairika anosanganisira:

1. Power Supplies: Bridge rectifiers zvinhu zvakakosha zvemagetsi emagetsi akasiyana siyana emagetsi nemidziyo.
2. Motor Controllers: Anoshandiswa mumaseketi ekudzora mota kushandura AC simba kuita DC simba rekutyaira mota dzemagetsi.
3. Modulation Process: Muredhiyo uye masisitimu ekutaurirana, mabhiriji anogadziridza anoshandiswa kune masaini modulation maitiro.
4. Welding Applications: Bhiriji rectifiers vanoita basa rakakosha mumakina ewelding, ichipa inodiwa DC simba rekuita welding process.
5. Home Appliances: Midziyo mizhinji yemumba, senge mafiriji uye maairconditioner, inovimba nemabhiriji anogadziridza pakushandura AC kuenda kuDC kune avo ekutonga masisitimu.

mhedziso

Mabhiriji anogadziridza zvinhu zvakakosha munyika yemagetsi, zvichiita kuti kushandurwa kwakanaka kwesimba reAC kuve rakagadzikana DC simba. Zvishandiso zvavo zvakasiyana-siyana zvinotenderera mumaindasitiri akasiyana siyana, zvichivaita chivakwa chakakosha chezvishandiso zvemagetsi zvisingaverengeki uye masisitimu. Kunzwisisa misimboti uye hunhu hwemabhiriji anogadziridza kwakakosha kune mainjiniya nevanofarira zvakafanana, sezvo zvichivapa simba rekushandisa kugona kwezvishandiso izvi mumapurojekiti nemashandisirwo avo.

Kana chinodiwa ichi chichikanganisa kuwanikwa kana kuburitswa kwezvigadzirwa, chienzanise nekugadzirwa kwePCB kwakawanda uye kusarudzwa kwePCB laminate usati watumira mafaira ekupedzisira kuti aongororwe.
