Pamwe wakambonzwa nezvazvo IPM chips, kana kuti zvimwe havatomboratidzi kujairana newe. Nekudaro, ivo vane akawanda maapplication muzvikamu zvakasiyana zveindasitiri uye zvakare mumapurojekiti eDIY ane mota, semuenzaniso, saka munyaya ino tichakurukura nezvadzo kuitira kuti vasave nechakavanzika kwauri.
Aya maseketi akabatanidzwa Dzinogona kuva dzinoshanda zvikuru, sezvauchaona, uye iwe unogona kuzviwana mumhando dzakasiyana kana kubva kune vakasiyana vagadziri, seInfineon, STMicroelectronics, nezvimwe.
Chii chinonzi IPM?
Un yakangwara simba module kana IPM (Intelligent Power Module) Iyo yepamberi, pa-chip solid-state simba switching mudziyo. Izwi rekuti "simba module" rinoreva kuvepo kwesimba rekuchinja chikamu (kazhinji IGBT-mhando transistor), uye iyo module "yakangwara" nekuti inosanganisira yekuwedzera kutonga uye kudzivirira wedunhu. Chinangwa ndechekuita optimize mashandiro uye kufambisa dhizaini nekuita kwemhinduro yese.
IPMs inoshandisa semiconductor zvishandiso zve high power switching. Midziyo iyi inogona kuve FET, BJT kana IGBT, iyo yekupedzisira ichinyanya kuwanda, kunyangwe zvese zvichienderana nekushandisa iyo IC iyi ichashandiswa.
IPM inosanganisira zvakawanda kupfuura kungobatidza nekudzima transistor, uye inobatanidza zvinhu zvakakosha sezvavanogona kuva:
- Gate drive circuits- Ivo vanofanirwa kuisa iyo chaiyo voltage uye kupa yakawanda yazvino yekukurumidza kushandura.
- Gate drive logic- Inogona kugadzirwa kudzivirira yakakwirira-rutivi uye yakaderera-parutivi IGBTs kubva mukuitisa panguva imwe chete. Kuita uku kunozivikanwa sekudzivirira kwerwendo, kudzivirira kwemuchinjiko, kana kuvharisa maseketi.
- kudzivirira matunhu- Vanofanirwa kukwanisa kuona uye kugadzirisa overcurrent, overvoltage, short circuit uye undervoltage mamiriro.
- Kukurukurirana kushanda- Kana iyo sisitimu ichida kuchengetedza matanda ezviitiko zvekukanganisa kana tembiricha yekushanda, imwe nzira yekutaurirana mashandiro anozodiwa.
- Power factor kugadzirisa (PFC)-Mamwe maapplication anoda simba factor kururamiswa (PFC).
Pakati pema IPM pamusika, tinogona kuwana nhamba huru yemamodheru, mamwe acho inogadzirwa nemakambani akadai seInfineon kana STMicroelectronics, uye zvakanyanya kuitirwa chikamu chemotokari, kune akasiyana enjini ekudzora masisitimu, kunyangwe achigona kuwanikwa mune mamwe akawanda maapplication...
Mhando kana mhuri
ari mhuri dzeiyi IPM module Zvekutengesa dzimwe nguva zvinogona kukamurwa zvichienderana nehunhu, hwakadai se:
- tsindirana: Iwo akabatanidzwa zvakanyanya uye compact simba modules. Iwo akagadzirirwa kutyaira mota mumashandisirwo kubva kumidziyo kusvika kune mafeni, pombi uye zvakajairika chinangwa chekutyaira zvikamu. Ivo zvakare vanosanganisira iyo CIPOS Nano uye Micro yakatevedzana, pakati pevamwe, inova mhuri ye Ultra-compact uye yakanyanya kusanganiswa magetsi mamodule evatengi, ekugara uye akareruka maindasitiri ekushandisa. Kune zvakare kune matatu-phase masisitimu.
- Standard: Iwo akasimba uye anorerutsa dhizaini yemotor drive system. Inosanganisira zvigadzirwa kubva pamusoro akaiswa CIPOS Tiny, Nano, Micro uye Mini kune akajairwa CIPOS modules anovhara simba renji kubva pa20W kusvika 5kW.
- mutambo: yakagadzirirwa kushandiswa kwemagetsi epamusoro-soro kana kushandiswa kunoda kushanda kwepamusoro maererano nekushanda kwesimba, simba remagetsi, kusimba kwehurongwa uye kuvimbika zvichienzaniswa nekare.
Imwe neimwe yakagadzirirwa akasiyana maapplication kana zvinodiwa, izvo zvinoenderana nezvaunoda.
Zvishandiso zveIPMs
ari IPM inonyanya kushamwaridzana nekutonga kwemotokari, asi ivo vanoshandiswawo mumasisitimu emagetsi asingachinjiki, ma inverters uye masisitimu emagetsi anovandudzwa, nezvimwe. Naizvozvo, vanogona kuwanikwa mune yakawanda yemidziyo, yakadai se:
- Kudzora injini yemotokari- IPMs dzakakosha mukutonga kwemotokari nekuda kwekugona kwavo kubata mafungu epamusoro uye ma voltages, pamwe nekugona kwavo kupa dziviriro uye kutonga.
- Unterruptible Power Systems (UPS)-Inoshandiswa muUPS/UPS kupa yakavimbika uye inogara iripo magetsi sosi.
- Vashanduri/inverters: iripowo mumasisitimu ekushandura yakananga ikozvino kuita inochinjanisa ikozvino.
- Renewable energy systems: IPMs inogona kunge iri mumasisitimu akadai solar nemhepo simba masisitimu, kushandura uye kutonga simba rinogadzirwa.
- Appliances: kudzora mota uye zvimwe zvinhu zvinoda simba.
