Iyo yemusika maitiro emagetsi modules!

Mafambiro emusika wesimba modules!

Mumakore achangopfuura, nekukurumidza kukura kwesimba remagetsi tekinoroji, hukama pakati pemagetsi emagetsi uye basa revanhu uye hupenyu hwave huchiwedzera kuswedera, uye zvigadzirwa zvemagetsi hazviparadzaniswe kubva kune yakavimbika magetsi.Mumakore ekuma1980, magetsi ekombuta akanyatsoona modularization yekuchinja magetsi., akatungamira mukupedzisa kutsiviwa kwemagetsi ekombuta.Mumakore ekuma1990, kushandura magetsi kwakapinda munzvimbo dzakasiyana-siyana dzemagetsi nemagetsi.Chirongwa-chinodzorwa switch, kutaurirana, yemagetsi yekuyedza midziyo yemagetsi, uye yekudzora midziyo yemagetsi zvakashandiswa zvakanyanya.Kuchinja magetsi kwakasimudzira kushandura magetsi Kukurumidza kukura kwehunyanzvi.Ikozvino, zvikumbiro zvehungwaru mundima dziri kusimukira dzakadai sedhijitari TV, LED, IT, chengetedzo, njanji inomhanya-mhanya, uye mafekitori akangwara achasimudzirawo kusimudzira kwemusika wekuchinja magetsi.

The switchingmagetsi ekupa module chizvarwa chitsva chekuchinja zvigadzirwa zvemagetsi, zvinonyanya kushandiswa muminda yakawanda seyehurumende, maindasitiri nemauto, zvinosanganisira kushandura midziyo, midziyo yekuwana, nharembozha, microwave communication, optical transmission, routers nedzimwe nzvimbo dzekutaurirana pamwe nemagetsi emotokari, Aerospace Wait.Nekuda kwehunhu hwepfupi dhizaini dhizaini, kuvimbika kwepamusoro uye nyore kusimudzira sisitimu, kushandiswa kwemamodules kuumba simba rekupa simba kwaita kuti kushandiswa kwemagetsi emodule kuwedzere uye kuwanda.Kunyanya mumakore achangopfuura, nekuda kwekukurumidza kuvandudzwa kwemasevhisi edata uye kuenderera mberi kwekusimudzira kweakagoverwa magetsi masisitimu, chiyero chekukura kwemagetsi emodule chapfuura icho chekutanga magetsi.

Vamwe vanhu vari muindastiri vanotenda kuti iyo yakakwira frequency yekuchinjisa magetsi ndiko kutungamira kwekusimudzira kwayo.Iko kusimukira kunofambira mberi, pamwe nekukura kweanopfuura manhamba maviri gore rega rega, akananga kwakanangana nekureruka, hudiki, hutete, hwakaderera ruzha, kuvimbika kwepamusoro uye anti-kupindira.

Kuchinja magetsi emagetsi modules kunogona kukamurwa kuita mapoka maviri: AC/DC uye DC/DC.Iyo DC/DC inoshandura ikozvino yave modularized, uye tekinoroji yekugadzira uye maitiro ekugadzira akakura uye akamisikidzwa kumba nekune dzimwe nyika, uye ave achizivikanwa nevashandisi.Nekudaro, iyo modularization yeAC / DC, nekuda kwehunhu hwayo, inosangana neyakaomarara tekinoroji uye maitiro ekugadzira matambudziko mukuita modularization.Pamusoro pezvo, kuvandudza uye kushandiswa kwekuchinja magetsi kune zvakakosha mukuchengetedza simba, kuchengetedza zviwanikwa nekuchengetedza nharaunda.

1. Kuwanda kwesimba hakusi kwepamusoro-soro, chete kwakakwirira

Nekushandiswa kwakanyanya kweiyo semiconductor tekinoroji, kurongedza tekinoroji uye yakakwira-frequency yakapfava switching, simba remagetsi emodule magetsi riri kuramba richikwira nekukwira, mashandiro ekushandura ari kuramba achikwira, uye application iri kuita nyore uye nyore.Ikozvino kushandurwa kutsva uye kurongedza tekinoroji inogona kuita kuti simba remagetsi remagetsi ripfuure (50W/cm3), rakapetwa kaviri kuwanda kwesimba remagetsi echinyakare, uye kushanda kwayo kunogona kudarika 90%.Kubudirira kwekuita, iine 4x yakakwirira simba density pane inofananidzwa inoshandura iripo pamusika, inogonesa inoshanda yeHVDC magetsi ekugovera zvivakwa mumashandisirwo akadai sedhata data, nharembozha uye maindasitiri.

2. Low voltage uye yakakwirira ikozvino

Nekudzikira kwevoltage yekushanda yemicroprocessor, simba rekubuda remagetsi emodule radonhawo kubva kune yakapfuura 5V kuenda kune yazvino 3.3V kana kunyange 1.8V.Iyo indasitiri inofanotaura kuti iyo inobuda voltage yemagetsi inodonha zvakare pazasi 1.0V.Panguva imwecheteyo, ikozvino inodiwa nedunhu rakabatanidzwa inowedzera, inoda kuti magetsi ape simba guru rekubuda.Kune 1V/100A module magetsi ekupa, iyo inoshanda mutoro wakaenzana ne0.01, uye tekinoroji yechinyakare yakaoma kuzadzisa izvo zvakaoma dhizaini zvinodiwa.Panyaya yemutoro we10m, imwe neimwe m kuramba munzira yekuremerwa kunoderedza kushanda zvakanaka negumi, uye kupikisa kwewaya kwebhodhi rakadhindwa redunhu, kuteedzera kuramba kweinductor, kupikisa kweMOSFET uye kufa. wiring yeMOSFET, nezvimwewo zvine simba.

Tatu, tekinoroji yekudzora tekinoroji inoshandiswa zvakanyanya

Iyo switching power supply module inoshandisa dhijitari chiratidzo chekudzora (DSC) tekinoroji kudzora yakavharwa-loop mhinduro yemagetsi, uye inoumba yedhijitari yekukurukurirana interface nenyika yekunze.Iyo modular magetsi ekushandisa uchishandisa dhijitari yekudzora tekinoroji itsika nyowani mune ramangwana kuvandudzwa kweiyo modular magetsi emagetsi indasitiri, uye kune zvishoma zvigadzirwa parizvino., Mazhinji makambani emagetsi emodule haagone dhijitari inodzorwa module magetsi ekupa tekinoroji.Indasitiri mukati vanotenda kuti mune zvakawanda zvikumbiro, chinodiwa chekuvandudza simba remagetsi chinotungamira kudiwa kwesimba rekutonga ICs mugore rinotevera.Mushure memakore akati wandei ebudiriro inononoka, manejimendi emagetsi edhijitari apinda padanho rekukura nekukurumidza.Kwemakore gumi anotevera, tsvakiridzo yakanangana nezvezvigadzirwa zvinoshandisa simba zvinotarisirwa kufambisa kutorwa kwesimba redhijitari manejimendi mumashandisirwo akadai seDC-DC converters.

Chechina, iyo yakangwara simba module inotanga kupisa

Iyo yakangwara simba module haingobatanidzi simba switching mudziyo uye dhiraivha yekutyaira pamwe chete.Iyo zvakare ine yakavakirwa-mukati yekutadza kuona maseketi senge overvoltage, overcurrent uye overheating, uye inogona kutumira masaini ekuona kuCPU.Iyo inoumbwa neyakakura-kumhanya uye yakaderera-simba kufa, yakagadziridzwa gedhi dhiraivha redunhu uye nekukurumidza kudzivirira redunhu.Kunyangwe tsaona yemutoro kana kushandiswa zvisina kunaka kukaitika, IPM pachayo inogona kuvimbiswa kusakuvadzwa.IPMs inowanzo shandisa maIGBT semagetsi ekuchinja zvinhu, uye ane zvimiro zvakasanganiswa zvine akavakirwa-mukati mazvino sensors uye dhiraivha maseketi.IPM iri kuhwina yakawanda uye yakawanda misika nekuvimbika kwayo kwepamusoro uye nyore kushandisa, kunyanya yakakodzera ma frequency converters uye akasiyana inverter magetsi ekushandisa ekutyaira mota.Chigadzirwa chemagetsi chemagetsi chakanakisa.

Kuchinja magetsi emagetsi modules kunoramba kuchivandudza kubatanidzwa uye hungwaru, uye indasitiri iri kutsvanzvadzira kupa yakakwira simba density kurongedza, uye akangwara emagetsi ma module anozowanawo budiriro huru.Kunyangwe iyo switching power supply musika ine zvinoyevedza tarisiro, iyo yepamusoro-yekupedzisira musika parizvino inotongwa nemhando dzepasirese.Zvigadzirwa zvemuno zvinofanirwa kuenderera mberi nekusimbisa dhizaini dhizaini, kutonga kwemhando, uye kuvimbika kuitira kuti vatore musika uyu mukuru.
