Gwaro reBhodhi reMagetsi eSiteshi reVatengi vePCB

Shandisa peji rino semuongorori wakakura wemabhodhi emagetsi. Kana purojekiti yacho yatove padanho rekuongorora marongerwo ehurongwa, ienzanise nedhizaini yePCB yemagetsi ; yekushandura ma converters kana ma inputs anonzwa EMI, mapeji ekugadzira marongerwo eSMPS PCB uye mapeji ekugadzira maPCB emagetsi anopinda zvakadzama musarudzo dzinokanganisa ruzha, kupisa, kubvisa creepage, uye kubatanidzwa kunodzokororwa.

Bhodhi remagetsi ndiro gamba risingakudzwe riri shure kwekushanda zvakanaka kwemidziyo yedu yemagetsi . Ichi chikamu chisinganyanyi kukosha chinoshandura uye chinodzora simba kubva kwarinobva kuti chipe simba kune zvikamu zvakaoma zvinoita kuti midziyo yedu ive mupenyu. Mukuongorora uku kwakadzama, tichaburitsa zvakavanzika zvemabhodhi emagetsi, tichiongorora magadzirirwo awo akaomarara, mashandiro awo, uye basa rakakosha mukupa simba nyika yedhijitari. Saka, ngatitangei rwendo rwekunzwisisa mashandiro emukati mechinhu ichi chakakosha chemagetsi.

Izvo Zvinokosha zveSimba reKugovera Circuit Board

Pakati payo, bhodhi rekupa magetsi redunhu rinogadzirwa kuti riite basa rakakosha rekushandura uye kuendesa simba kumidziyo yemagetsi. Aya mabhodhi edunhu anogona kuwanikwa mune yakawanda spectrum yemidziyo, kubva kune yakavharirwa muAC zvitoro, izvo zvinopa alternating current (AC), kune midziyo inoshandiswa nebhatiri inotsamira pane yakananga ikozvino (DC). Imwe neimwe magetsi edhisheni bhodhi inouya nerabel inotsanangura yayo yekushandisa voltage uye yazvino, ichipa ruzivo rwakakosha rwekubatanidza kwakaringana mumasisitimu emagetsi. Uyezve, aya mabhodhi edunhu anowanzo ratidza zvinhu zvinodzivirira, senge fuse, kuchengetedza kubva kune zvakawandirwa uye kudzivirira kukuvadzwa kwemagetsi emagetsi uye anoenderana nedunhu. Pamusoro pezvo, pakuyedza uye nezvinangwa zvekuyedza, magetsi anochinja-chinja anowanikwa, achibvumira mainjiniya uye matekinoroji kukwenenzvera-tune voltage uye mazinga aripo sezvinodiwa.

Anatomy yeBasic Power Supply Circuit Board

Nepo magetsi emagetsi edunhu mabhodhi achisiyana mukuomarara, kunyangwe iwo akanyanya kukosha anoumbwa nezvinhu zvakakosha zvinofambisa basa ravo rekutanga. Izvi zvinosanganisira:

1. Transformer:

• MuAC magetsi emagetsi edunhu mabhodhi, ma transformer anoita basa rakakosha mukudzika pasi kana kukwira mavoltages.
• Nhanho-pasi ma transformer anoderedza voltage inouya kuti ienderane nezvinodiwa nedunhu.
• Mimwe michina ine simba-akakwira inoda nhanho-up transformers kuti ipe iyo inodiwa voltage.
• Kusiyana kwepasi rose mumagetsi ekupa, senge 110-120 volts muUS kana 220-230 volts kune dzimwe nyika, zvinoda kushandiswa kwema converter kugadzirisa zvishandiso zvinoenderana.

2. Rectifiers:

• MuAC kusvika kuDC magetsi emagetsi edunhu mabhodhi, anogadziridza anoshandura AC voltage kuita DC voltage.
• Kugadzirisa inhanho yakakosha inoita kuti dunhu rishande pane inodiwa DC voltage.

3. Capacitors uye Inductors:

• Zvinhu izvi zvinoshanda semafirita ekudzikisa ruzha rwemagetsi uye ripple, zvichikonzera kuburitsa uye kugadzikana kweDC.

4. Voltage Regulation:

• DC magetsi emagetsi edunhu mabhodhi, anofambiswa nemabhatiri, anoda voltage regulation.
• Uyu murairo unogona kuwanikwa kuburikidza nemasekete akabatanidzwa (ICs) kana seti yeZener diodes kuchengetedza inowirirana inobuda voltage.

5. Multiple Voltage Outputs:

• Mimwe midziyo yemagetsi inoda kubuda kwemagetsi akawanda, se +5V, -5V, uye +/- 12 kana 15 volts.
• Simba rimwe chete remagetsi redunhu bhodhi rinogona kugadzira ese aya anodiwa voltages ekushanda kwechishandiso.
• Variable magetsi ekushandisa, kana Variacs, inopa vashandisi kuchinjika kwekugadzirisa inobuda voltages sezvinodiwa.

Kudzivirirwa Kwedunhu: Kuve nechokwadi Chekuchengetedza uye Kuvimbika

Kuchengetedza uye kuvimbika kwakakosha zvakanyanya munzvimbo yemagetsi. Kudzikamisa zvingangoitika, magetsi emagetsi edunhu mabhodhi akashongedzerwa akasimba edunhu rekudzivirira masisitimu. Aya maitiro anoshanda kuchengetedza sisitimu uye zvikamu zvayo. Ngationgororei mamwe maitiro akajairika ekudzivirira edunhu:

Kudzivirira Kupfuura Mwero : Zviitiko zvekuwedzera kwemagetsi, zvinokonzerwa nekushomeka kwemasekete kana kudhonza kwemagetsi zvakanyanya, zvinogona kukuvadza zvikamu kana kutungamira kumamiriro ezvinhu ane njodzi. Nzira dzekudzivirira kupfuura kwemagetsi zvakanyanya, dzakadai semafusi kana macircuit breakers, dzinoshandiswa kukanganisa circuit nekudzivirira kuyerera kwemagetsi zvakanyanya, nokudaro zvichichengetedza sisitimu.

Kudzivirira Kukwira Kwemagetsi : Kukwira kwemagetsi kana kukwira kwemagetsi kunogona kuitika nekuda kwekuchinja kwesimba kana kurohwa nemheni, zvichikonzera njodzi kuzvinhu zvemagetsi zvinonzwa. Midziyo yekudzivirira kukwira kwemagetsi, senge transient voltage suppressors kana voltage clamping circuits, inoshandiswa kutsausa voltage yakawandisa uye kudzivirira system kubva mukukuvadzwa.

Kudzivirira Kupisa Kwakadarika : Kupisa kwakanyanya kunogona kukanganisa mashandiro echikamu kana kutokonzera kutadza kushanda zvakanaka. Nzira dzekudzivirira kupisa kwakawandisa, dzakadai semasensa ekupisa kana maswichi anonzwa kupisa, dzinoshandiswa kutarisa nekudzora kupisa kwezvinhu zvakakosha. Dzinokonzeresa zviito zvakaita sekuderedza simba kana kuvhura nzira dzekutonhodza kudzivirira kupisa zvakanyanya.

Dziviriro yeESD : Zviitiko zveElectrostatic discharge (ESD) zvinogona kuitika kana magetsi asingachinji akaburitswa pazvikamu zvemagetsi, zvichikonzera kukuvara. Zvishandiso zvekudzivirira zveESD, zvakaita se transient voltage suppressors kana ESD diodes, zvakabatanidzwa mukugadzirwa kwedunhu kuti zvibvise kuburitswa kunokuvadza zvakachengeteka uye kudzivirira zvikamu zvinonzwa.

Dziviriro yeReverse Polarity : Kubatanidza magetsi nereverse polarity kunogona kukonzera kukuvara kwechikamu kana kusashanda zvakanaka kwesystem. Maseketi ekudzivirira reverse polarity, akadai se diodes kana MOSFET, anoshandiswa kudzivirira kuyerera kwemagetsi munzira isiriyo uye kuve nechokwadi chekuti polarity yakarurama.

Nekubatanidza idzi nzira dzekudzivirira dzedunhu, magetsi emagetsi edunhu mabhodhi anogona kuwedzera kuchengetedzwa uye kuvimbika. Aya matanho anochengetedza kubva kune yakawandisa, kuwandisa, kuwedzeredza, ESD zviitiko, uye reverse polarity, kuderedza njodzi yekukuvadzwa kwechikamu, kutadza kwehurongwa, kana njodzi dzinogona kuitika.

Iyo Isingaonekwe Musana weMazuvano Electronics

Sezvo isu tichifarira zvinoshamisa zvetekinoroji yemazuva ano, zvakakosha kuti tibvume gamba risingafadzi, iro magetsi edunhu redunhu. Pasina iyo, midziyo yedu yemagetsi yaizoramba isina simba uye inert. Aya mabhodhi asina kuzvikudza anovimbisa chinyararire kuyerera kwakadzikama uye kwakavimbika kwesimba kune chimwe chinhu, zvichibvumira magajeti edu kushanda zvisina musono. Saka, nguva inotevera paunosimbisa mudziyo wako, tora nguva yekutenda iyo yakaoma symphony yezvikamu mukati meiyo inoshamisira yedunhu bhodhi, zvichiita kuti nyika yedu yedhijitari ibudirire.

Munyika yemagetsi iri kuramba ichichinja-chinja, hunyanzvi husina miganhu. Highleap Electronic inomira sesimba guru mukupa mhinduro dzemazuva ano dzemabhodhi emagetsi. Nezvishandiso zvemazuva ano nehunyanzvi, tinopa mhinduro dzePCB dzemagetsi dzakagadzirirwa zvaunoda. Kuti uwane kubvunzana kunosimbisa mabasa ako emagetsi, tinya pano.

Kazhinji, mabhodhi emagetsi ndiwo anofambisa simba risingaperi munyika yemagetsi. Anovhara musiyano uripo pakati pemagetsi nemidziyo yemagetsi, zvichiita kuti pave nekushanda kwakabatana uye kwakavimbika. Kunzwisisa kuoma kwemabhodhi aya emagetsi kunotibvumira kunzwisisa kukosha kwawo nebasa rawo mukusimudzira nguva yedhijitari. Ungave uri mainjiniya ane ruzivo kana munhu anoda kuziva zvakawanda, kuongorora zvakadzama mabhodhi emagetsi emagetsi kunoburitsa pachena zvishamiso zvakavanzika zvinofambisa nyika yedu yakabatana mberi.

Kana chirongwa ichi chikachinja kubva pakutsvagisa kuenda kuRFQ, ongorora kugona kwePCB kugadzira uye simba rekushandura PCB kuti zvinhu, maitiro, uye zvinodiwa pakuongorora zvirambe zvakaenzana.
