Simba manejimendi IC machipi anonyanya kubata magetsi ekushandura simba, kugovera, kuona uye mamwe masimba emagetsi mumasisitimu emidziyo yemagetsi.Simba manejimendi semiconductor kubva kumidziyo irimo, iyo yekusimbisa yakajeka pane simba manejimendi akabatanidzwa redunhu (simba manejimendi IC, inonzi sesimba manejimendi chip) chinzvimbo uye basa.Simba manejimendi semiconductor inosanganisira zvikamu zviviri, zvinoti simba manejimendi akabatanidza redunhu uye simba manejimendi discrete semiconductor mudziyo.
Kune akawanda marudzi emagetsi manejimendi akasanganiswa maseketi, ayo anogona kukamurwa kuita voltage regulation uye interface maseketi.Voltage modulator inosanganisira mutsara yakaderera voltage kudonhedza regulator (kureva LOD), yakanaka uye isina kunaka inobuda nhevedzano wedunhu, mukuwedzera, hapana pulse wide modulation (PWM) mhando switching circuit, nezvimwe.
Nekuda kwekufambira mberi kwetekinoroji, saizi yemuviri yedunhu redhijitari mune yakabatanidzwa redunhu chip iri kuita diki uye diki, saka magetsi ekushanda ari kusimukira akananga kuderera kwemagetsi, uye nhevedzano yemagetsi matsva ekudzora anobuda panguva chaiyo.Simba manejimendi interface redunhu rinonyanya kusanganisira interface mutyairi, mota mutyairi, MOSFET mutyairi uye yakakwira voltage / yakakwira ikozvino kuratidza mutyairi, nezvimwe.
Akajairika marudzi masere emagetsi manejimendi IC chip classification
Simba manejimendi discrete semiconductor zvishandiso zvinosanganisira mamwe echinyakare simba semiconductor zvishandiso, izvo zvinogona kukamurwa kuita mapoka maviri, imwe inosanganisira rectifier uye thyristor;Imwe yacho imhando yetriode, inosanganisira simba bipolar transistor, ine MOS chimiro chesimba remumunda mhedzisiro transistor (MOSFET) uye insulated gedhi bipolar transistor (IGBT).
Muchikamu nekuda kwekuwanda kweiyo simba manejimendi ics, magetsi semiconductors akatumidzwa zita rekuti simba rekutonga semiconductors.Izvo chaizvo nekuti akawanda akabatanidzwa maseketi (IC) munzvimbo yekugovera magetsi, vanhu vanowedzera kune simba manejimendi kudaidza nhanho iripo yemagetsi ekupa magetsi.
Simba manejimendi semiconductor mune inotungamira chikamu chesimba manejimendi IC, inogona kupfupikiswa seinotevera 8.
1. AC/DC modulation IC.Iyo ine yakaderera voltage control circuit uye yakakwira voltage switching transistor.
2. DC/DC modulation IC.Inosanganisira boost/step-down regulators, uye mapombi ekuchaja.
3. simba factor control PFC pretuned IC.Ipa simba rekuisa dunhu rine simba rekugadzirisa basa.
4. pulse modulation kana pulse amplitude modulation PWM/ PFM control IC.A pulse frequency modulation uye/kana pulse wide modulation controller yekutyaira ekunze switch.
5. linear modulation IC (yakadai semutsara yakaderera voltage regulator LDO, nezvimwewo).Inosanganisira kumberi uye kwakashata regulators, uye yakaderera voltage inodonha LDO modulation machubhu.
6. bhatiri kuchaja uye manejimendi IC.Izvi zvinosanganisira kubhadharisa bhatiri, kudzivirira uye simba rekuratidzira ics, pamwe ne "smart" bhatiri ics yebhatiri data data.
7. Hot swap board control IC (isina simba rekuisa kana kubvisa imwe interface kubva pakushanda system).
8. MOSFET kana IGBT kushandura basa IC.
Pakati peaya masimba manejimendi ics, voltage regulation ICS ndiyo inokurumidza kukura uye inogadzira zvakanyanya.Iwo akasiyana emagetsi manejimendi ics anowanzo kubatanidzwa nehuwandu hwehukama hwekushandisa, saka mamwe marudzi emidziyo anogona kunyorwa kune akasiyana maapplication.
Iyo tekinoroji maitiro ekutonga kwesimba kwakanyanya kushanda zvakanaka, kuderera kwesimba rekushandisa uye kungwara.Kuvandudza kushanda kunosanganisira zvinhu zviviri zvakasiyana: kune rumwe rutivi, kushanda kwese kwesimba rekushandura kunochengetedzwa apo kuderedza ukuru hwemichina;Kune rumwe rutivi, saizi yekudzivirira haina kuchinjika, inovandudza zvakanyanya kushanda zvakanaka.
Kudzikira kwepasi-kuramba mukushandurwa kwe AC/DC kunosangana nezvinodiwa zvemamwe maadapter uye magetsi emagetsi mumakomputa uye maapplication ekufonera.Musimba redunhu dhizaini, iyo general standby simba rekushandisa yakaderedzwa kusvika pazasi 1W, uye kushanda kwesimba kunogona kuwedzerwa kusvika kupfuura 90%.Kuti uwedzere kudzikisira ikozvino mashandisirwo emagetsi ekumira, matsva ekugadzira IC matekinoroji uye kubudirira mune yakaderera simba redunhu dhizaini inodiwa.
