Tekinoroji yemagetsi ndiyo musimboti wemidziyo yemazuva ano yemagetsi, uye sezvo tekinoroji inofambira mberi, kudiwa kwekuvandudzwa kwesimba rekuita kuri kuramba kuchikwira. Muchirevo chechinyorwa chino, kusarudzwa kwezvinhu zvesemiconductor kunova kwakakosha. Nepo zvechinyakare silicon (Si) semiconductors zvichiri kushandiswa zvakanyanya, zvinhu zviri kubuda zvakaita seGallium Nitride (GaN) neSilicon Carbide (SiC) zviri kuramba zvichiwana mukurumbira muhunyanzvi hwekuita simba repamusoro. Ichi chinyorwa chichaongorora mutsauko uripo pakati pezvitatu izvi mumagetsi tekinoroji, mamiriro ekushandisa kwavo, uye maitiro emusika aripo kuti unzwisise kuti sei GaN neSiC zviri kuita zvakakosha mune ramangwana masisitimu emagetsi.
1. Silicon (Si) - The Traditional Power Semiconductor Material
1.1 Hunhu uye zvakanakira
Silicon ndiyo piyona zvinhu mumunda wesimba semiconductor, ine makumi emakore ekushandiswa muindasitiri yemagetsi. Si-based zvishandiso zvine maitiro ekugadzira akakura uye yakafararira chigadziko chekushandisa, ichipa mabhenefiti senge mutengo wakaderera uye yakanyatso kusimbiswa yekugovera cheni. Midziyo yeSilicon inoratidza yakanaka conductivity yemagetsi, ichiita kuti ive yakakodzera kune akasiyana-siyana emagetsi emagetsi maapplication, kubva kune yakaderera-simba mutengi zvemagetsi kune epamusoro-simba maindasitiri masisitimu.
1.2 Kuganhurirwa
Nekudaro, sezvo kudiwa kwehunyanzvi hwepamusoro uye kushanda mumasisitimu emagetsi kuchikura, izvo zvinogumira zvesilicon zvishandiso zvinova pachena. Kutanga, silicon inoita zvisina kunaka pasi pe-high-frequency uye high-temperature mamiriro, zvichiita kuti kuwedzera kurasikirwa kwesimba uye kuderedza kushanda kwehurongwa. Pamusoro pezvo, silicon yakaderera yekupisa yekupisa inoita kuti kudziya kwemafuta kuomese mune yakakwirira-simba maapplication, inokanganisa kuvimbika kwehurongwa uye hupenyu.
1.3 Nzvimbo dzekushandisa
Kunyangwe zvipingamupinyi izvi, michina yesilicon inoramba ichitonga mune zvakawanda zvechinyakare zvikumbiro, kunyanya mumidziyo isingadhure mutengi uye yakaderera-kusvika-pakati-simba maapplication akadai seAC-DC converters, DC-DC converters, midziyo yemumba, uye macomputer emunhu.
2. Gallium Nitride (GaN) - Chinhu Chinobuda Chikuru-chinoshanda
2.1 Hunhu uye zvakanakira
Gallium Nitride ibhendi rakakurasemiconductorzvinhu zvinoratidzirwa nemunda wakanyanya kuparara, yakakwira erekitironi kufamba, uye yakaderera pa-resistance. Kuenzaniswa nesilicon, GaN zvishandiso zvinogona kushanda pamafafitera epamusoro, zvichideredza zvakanyanya saizi yezvinongoita zvinhu mumagetsi uye kuwedzera simba remagetsi. Zvakare, zvishandiso zveGaN zvinogona kukwidziridza simba system kushanda zvakanaka nekuda kwekudzikira kwadzo uye kurasikirwa kwekuchinja, kunyanya pakati nepakati-pasi-simba, yakakwirira-frequency application.
2.2 Kuganhurirwa
Pasinei nekukosha kwekuita kwakakosha kweGaN, mari yekugadzira yayo inoramba yakakwira, ichimisa kushandiswa kwayo kune yakakwirira-yekupedzisira maapplication uko kushanda uye ukuru kwakakosha. Pamusoro pezvo, tekinoroji yeGaN ichiri mudanho rekutanga rebudiriro, nekuvimbika kwenguva refu uye kukura kwekugadzira kukuru kunoda kumwe kusimbiswa.
2.3 Nzvimbo dzekushandisa
GaN michina 'yepamusoro-frequency uye yakakwirira-inoshanda maitiro zvakakonzera kuti vagamuchirwe muminda yakawanda ichiri kubuda, kusanganisira majaja anokurumidza, 5G yekutaurirana magetsi emagetsi, inverters inoshanda, uye aerospace zvemagetsi. Sezvo tekinoroji ichifambira mberi uye mutengo uchidzikira, GaN inotarisirwa kuita basa rakakosha muhuwandu hwakawanda hwekushandisa.
3. Silicon Carbide (SiC) - The Preferred Material for High-Voltage Applications
3.1 Hunhu uye zvakanakira
Silicon Carbide imwe yakafara bandgap semiconductor zvinhu zvine yakakwira zvakanyanya kuputsa munda, thermal conductivity, uye electron saturation velocity kupfuura silicon. Zvishandiso zveSiC zvinonyanya kukwira-voltage uye yakakwirira-simba maapplication, kunyanya mumotokari dzemagetsi (EVs) uye maindasitiri inverters. SiC's high voltage kushivirira uye kuderera kwekuchinja kurasikirwa kunoita kuti ive sarudzo yakanaka yekushandura magetsi uye simba density optimization.
3.2 Kuganhurirwa
Zvakafanana neGaN, SiC zvishandiso zvinodhura kugadzira, zvine maitiro akaomarara ekugadzira. Izvi zvinomisa kushandiswa kwavo kune yakakwirira-kukosha maapplication akadai seEV magetsi masisitimu, renewable simba masisitimu, yakakwira-voltage inverters, uye smart grid michina.
3.3 Nzvimbo dzekushandisa
SiC's inoshanda, yakakwira-voltage maitiro inoita kuti ishandiswe zvakanyanya mumagetsi emagetsi emagetsi anoshanda munzvimbo dzepamusoro-simba, yepamusoro-tembiricha, senge EV inverters uye majaja, high-power solar inverters, mhepo magetsi masisitimu, nezvimwe. Sezvo kudiwa kwemusika kuchikura uye tekinoroji ichifambira mberi, kushandiswa kweSiC zvishandiso muminda iyi kucharamba kuchiwedzera.
4. Market Trend Analysis
4.1 Kukurumidza Kukura kweGaN uye SiC Markets
Parizvino, musika wemagetsi tekinoroji uri kuita shanduko, zvishoma nezvishoma uchichinja kubva pachinyakare silicon zvishandiso kuenda kuGaN neSiC zvishandiso. Zvinoenderana nemishumo yekutsvagisa musika, musika weGaN neSiC zvishandiso uri kukura nekukurumidza uye unotarisirwa kuenderera mberi nekukura kwayo kwepamusoro mumakore anotevera. Iyi tsika inonyanya kutungamirirwa nezvikonzero zvakawanda:
