Akagadziridza Performance: Zvishandiso zvemagetsi, senge mamicrocontrollers, maseketi akabatanidzwa, uye zvimwe zvikamu zvesemiconductor, zvinowanzoda yakagadzikana uye inowirirana DC voltage kuti ishande nemazvo. Kusefa kunovimbisa kuti voltage inopihwa kuzvikamu izvi inosangana nezvayo, kudzivirira kusashanda zvakanaka uye kuwedzera kushanda kwese.
4. Ruzha rweMagetsi rwakaderedzwa: Kusefa kunobatsirawo kudzikisira ruzha rwemagetsi kana kukanganisa mukubuda kweDC. Chero akasara eA AC zvikamu kana yakakwirira-frequency ruzha rwuripo mune yakagadziridzwa kubuda inogona kuwedzeredzwa neiyo kusefa capacitor. Izvi zvinonyanya kukosha mumashandisirwo anowanikwa zvikamu zvinonzwa ruzha.
5. Output Voltage Regulation: Kusefa capacitors kunobatsira kudzora inobuda voltage yeiyo yakazara-wave rectifier PCB. Ivo vanochengetedza vhezheni padanho risingachinjiki, kunyangwe paine misiyano mu AC yekupinza voltage. Uyu murairo unovimbisa kuti zvigadzirwa zvemagetsi zvinogamuchira simba rinoenderana uye rakavimbika.
6. Kudzivirira Voltage Droop: Kana iyo inobuda voltage yeinogadzirisa PCB ikatanga kudonha, kunyanya panguva yezvino kudiwa zvakanyanya, iyo yekusefa capacitor inogona kutsiva kudonha uku nekuburitsa simba rakachengetwa. Izvi zvinodzivirira kamwe kamwe voltage dips uye inovimbisa kushanda kwakagadzikana, kunyangwe pasi pemamiriro ekutakura akasiyana.

Kazhinji, kusefa kwakakosha mumaPCB ekugadzirisa magetsi akazara kuti pave nemagetsi akachena uye akasimba eDC. Izvi zvakakosha pakushanda zvakanaka kwemidziyo yemagetsi uye zvinoita kuti iwane magetsi anowirirana avanoda. Ingave iri mumagetsi emagetsi evatengi kana maindasitiri, kusefa kunobatsira kuvandudza mashandiro uye kuvimbika.

Mhando dzeMafirita Anoshandiswa muRectifier PCBs

Rectifier PCBs dzinowanzoda kuwedzera kusefa kuti uwane yakatsiga uye yakagadzikana DC voltage kubuda. Mhando dzakasiyana dzemafirita dzinogona kushandiswa, zvichienderana neiyo rectifier wedunhu uye mhando yeAC magetsi ekupa. Mhando huru dzemasefa anoshandiswa ndeaya:

Inductor Sefa:

Iri rudzi rwesefa rinoshandisa inductor munhevedzano nemutoro kutsetsenura zvinobuda. Inobatsira kuderedza ripple uye inopa yakati sandara yakabuda voltage ine yakaderera kushanduka. Nekudaro, mafirita einductor anogona kuve akakura uye anogona kunge achinzwa kukanganiswa kwemagetsi (EMI).

Kusefa kwecapacitor kunosanganisira kuisa yakakura capacitor mukuwirirana nemutoro. Inoshanda mukudzikisa ma pulsations kana ripple mune inobuda voltage, zvichikonzeresa yakatsetseka waveform. Kubudirira kwekusefa kwe capacitor kunoenderana necapacitance kukosha kweiyo capacitor uye kurwisa mutoro.

Compound Sefa:

Compound mafirita anosanganisa zvinhu zvakaita seanopikisa, capacitors, uye / kana inductors kuti awane akapfava ekubuda ma waveform. Semuenzaniso, sefa yekomboni inogona kusanganisira resistor-capacitor (RC) kana inductor-capacitor (LC) musanganiswa. Aya mafirita anorova chiyero pakati pekuita uye kuomarara, achipa yakagadziridzwa kutsetseka neane mwero chikamu chechikamu.

Sarudzo yerudzi rwesefa inoenderana nezvinhu zvakaita seyero inodiwa yekusefa, zvipingaidzo zvenzvimbo, kufunga kwemitengo, uye hunhu chaihwo hwekupinza AC chiratidzo. Vagadziri vanosarudza iyo yakakodzera sefa yekumisikidza kuti ive nechokwadi chekuti PCB inogadziridza inogadzira yakagadzikana uye yakachena DC voltage kubuda kwakakodzera kune magetsi emagetsi.

Iyo Bridge Rectifier PCB uye Center-Tap Rectifier PCB Inofananidza sei?

Kana uchienzanisa bhiriji rectifier PCB uye yepakati-tap rectifier PCB, pane akati wandei akakosha mutsauko:

Diode Inodiwa: Iyo bhiriji inogadzirisa PCB inoshandisa mana diode, nepo yepakati-tap rectifier PCB inoda madhiodhi maviri chete. Uyu mutsauko mukuverenga diode unobata mutengo wakazara wePCB, sezvo masilicon diode anowanzo kudhura pane epakati-tapped transformers.

Transformer Dependency: Kugadzira yepakati-tap rectifier PCB inogona kunetsa nekuda kwechinodikanwa cheyakatarwa yepakati-tapped transformer, inogona kudhura. Kusiyana neizvi, PCB inogadzirisa bhiriji inopa kuchinjika sezvo inogona kugadzirwa ine kana isina shanduri. Kana transformer ikashandiswa, yakajairika nhanho-kumusoro kana nhanho-pasi transformer inogona kushandiswa.

Voltage Handling: Iyo bhiriji rectifier PCB inokodzera maapplication anosanganisira akakwira voltages. Iyo ine yepamusoro Peak Inverse Voltage (PIV) ichienzaniswa neyepakati-tap rectifier PCB, ichiita kuti ive yakakodzera kune yakakwira-voltage application.

Transformer Utilization: Iyo bhiriji rectifier PCB inozvirumbidza yepamusoro shanduko yekushandisa ichienzaniswa neyepakati-tap rectifier PCB. Izvi zvinoreva kuti PCB inogadzirisa bhiriji inoshandisa shanduko zvakanyanya, zvichikonzera kuvandudza kushanda.

Nekudaro, pane kukanganisa kune bhiriji rectifier PCB. Nekuda kwekushandiswa kwema diode mana, kune mambure emagetsi anodonha pama diode panguva yekushanda, inova yakapetwa kaviri kudonha kwevoltage mune imwe diode inoshandiswa mucentre-tap rectifier circuit. Izvi zvinogona kukanganisa kushanda kwese uye kurasikirwa kwesimba mubhiriji rectifier PCB.

Muchidimbu, sarudzo pakati pebhiriji rectifier PCB uye yepakati-tap rectifier PCB zvinoenderana nezvinhu zvakaita semutengo, kuwanikwa kwematransformer, voltage zvinodiwa, uye nhanho inodiwa yedhizaini inoshanduka. Iyo bhiriji rectifier PCB inopa kuchinjika uye inokodzera yakakwira-voltage maapplication, nepo yepakati-tap rectifier PCB iri nyore mukugadzira asi inoda chaiyo centre-tapped transformer.

Zvakanakira uye Zvakaipa zveFull-Wave Rectifier PCBs

Advantages:

Yakazara-wave rectifier PCBs inopa akati wandei mabhenefiti pamusoro pevawo hafu-wave vamwe vavo. Chekutanga, ivo vanopa kaviri kunyatsoita zvichienzaniswa nehafu-wave rectifiers. Nekushandisa ese mahafu echiratidzo chekuisa, yakazara-wave rectifiers inoshandura simba rakawanda kubva kuAC kuenda kuDC, zvichikonzera kushanda kwepamusoro kwese.

Kechipiri, yakazara-wave rectifiers inoburitsa yakanyanya kuderera yakasara AC ripple mune inobuda ichienzaniswa nehafu-wave rectifiers. Izvi zvinobatsira kune maapplication anoda yakapfava DC inobuda waveform ine yakaderedzwa shanduko.

Chekupedzisira, full-wave rectifiers vane kugona kuendesa yakakwira yekubuda simba nekuda kwekuita kwavo kaviri. Izvi zvinoita kuti dzive dzakakodzera maapplication anoda simba rakawanda, senge magetsi emidziyo yemagetsi kana motor control circuits.
