Mumagetsi emazuva ano, hwaro hwechishandiso hunowanzo sarudza kugona kwehurongwa hwese. Zvishandiso zvesilicon carbide (SiC) zvakabuda sezvinhu zvinoshandura, zvichigonesa chizvarwa chitsva chemagetsi ane simba rakawanda, mafrequency akakwira, uye masisitimu esimba asingashandise simba zvakanyanya. Kubva pakurongeka kweatomu kwechikamu checrystalline kusvika kuchinoshandura simba chakabatanidzwa zvizere, SiC yakazvisimbisa senzira huru yekugonesa tekinoroji yesimba rechizvarwa chinotevera.
Chikamu: Hwaro hweZvinhu zveKushanda
Substrate ndiyo nzvimbo yekutanga yemudziyo wega wega weSiC-based power. Kusiyana nesilicon yakajairika, SiC ine bandgap yakakura yeinenge 3.26 eV, high thermal conductivity, uye high critical electric field. Hunhu uhwu hwemukati hunobvumira michina yeSiC kushanda pamagetsi akakwira, tembiricha yakakwira, uye switching speed nekukurumidza. Hunhu hwesubstrate, kusanganisira crystalline uniformity uye defect density, hunokanganisa zvakananga kushanda zvakanaka kwemudziyo, kuvimbika, uye kugadzikana kwenguva refu. Kukanganisika kwesubstrate kunogona kutungamira mukudziisa kwenzvimbo, kudzikira kwevoltage yekuputsika, uye kudzikira kwekushanda kwesystem, zvichisimbisa kukosha kwekunyatsorongeka kwezvinhu.
Kufambira mberi mune tekinoroji ye substrate, senge saizi huru dzewafer uye kudzikira kwehuwandu hwemadhenda, kwakaderedza mitengo yekugadzira uye kwakawedzera huwandu hwemashandisirwo. Kuchinja kubva kumawafer e 6-inch kuenda ku 12-inch, semuenzaniso, kunowedzera zvakanyanya nzvimbo inoshandiswa ye chip pa wafer, zvichiita kuti huwandu hwekugadzira huwedzere uye kudzikisa mitengo ye per-chip. Kufambira mberi uku hakungoiti kuti michina yeSiC ive nyore kushandisa kune mashandisirwo epamusoro senge mota dzemagetsi nema inverters emaindasitiri asiwo kunokurumidza kushandiswa kwavo muzvikamu zvitsva zvakaita sedata centers uye fast-charging infrastructure.
Kugadzira Zvishandiso: Kushandisa Substrate Advantage
Kushanda kwemodule yemagetsi kwakabatana zvakanyanya nekugadzirwa kwemidziyo yakavakirwa pamodule. Zvivakwa zvepamusoro zvakaita se trench-gate MOSFETs, superjunction devices, uye double-sided cooled modules zvinoshandisa hunhu hwepamusoro hwemagetsi nekupisa hweSiC substrates kuderedza kurasikirwa kwekufambisa nekuchinja, kuwedzera kugona kwekutakura magetsi, uye kutsigira kushanda kwema frequency akakwira.
Semuenzaniso, maMoFET eSiC MOSFET eTrench-gate anoderedza kuramba kwemhepo inoyerera uye anovandudza huwandu hwemasero, zvichikonzera kushanda zvakanaka mukushandiswa kwesimba guru. Midziyo yeSuperjunction, pamwe chete nemidziyo yepamusoro-soro, inobvumira kushanda kwemagetsi akawanda uku ichichengetedza kurasikirwa kwakaderera. Matekiniki ekutonhodza ane mativi maviri anovandudza manejimendi yekupisa, zvichibvumira mamodule madiki, akareruka, uye akavimbika anogona kushanda munzvimbo dzakaoma pasina mamwe masystem ekutonhodza.
Kukanganisa Kwedanho ReSisitimu: Kubva Pazvinhu Kuenda Pakushandura
Simba reZvigadziko zveSiCInodarika michina yega yega kusvika kumasisitimu emagetsi ese. Muma inverters emotokari dzemagetsi, ma substrates eSiC emhando yepamusoro anogonesa kushanda kwe800V-class, achitsigira kuchaja nekukurumidza uye kuwedzera mafambiro ekutyaira. Mumasisitimu esimba rinogona kushandiswazve senge ma inverters e photovoltaic uye ma converters ekuchengetedza simba, zvishandiso zveSiC zvakavakirwa pama substrates epamusoro zvinowana kushanda kwakanaka kwekushandura kupfuura 99%, zvichideredza kurasikirwa kwesimba uye kuderedza saizi yesystem nehuremu.
Kushanda kwemafrequency akakwirira kunofambiswa neSiC kunoderedza saizi yezvikamu zvisingashande, kusanganisira ma inductor nema capacitor. Zvikamu zvidiki zvisingashande zvinobvumira magadzirirwo esystem akamanikana uye anoshanda zvakanaka pakupisa. Munzvimbo dzemaindasitiri, izvi zvinoshandura kushandiswa kwesimba kushoma, saizi diki dzenzvimbo dzakavharirwa, uye kuvimbika kwesystem kuri nani. Pamashandisirwo edzimba, kushanda zvakanaka kwema inverters nema converters akavakirwa paSiC kunobatsira mukuchengetedza mari uye kuderedza kukanganisa kwezvakatipoteredza nekufamba kwenguva.
Kugadzira Flywheel: Kubatanidzwa kwezvinhu, mudziyo, uye sisitimu
Kugadzirwa kwemagetsi eSiC kunotevera kutenderera kwekuzvisimbisa. Kuvandudzwa kwemhando ye substrate nehukuru hwewafer kunoderedza mari yekugadzira, izvo zvinokurudzira kushandiswa kwakakura kwemidziyo yeSiC. Kuwedzerwa kwekushandiswa kunoita kuti huwandu hwekugadzira huwedzere, zvichideredza mari uye zvichipa zviwanikwa zvekuenderera mberi nekutsvaga muzvinhu zvitsva uye zvishandiso.
Kufambira mberi kwazvino kunoratidza mhedzisiro iyi ye flywheel. Kuchinja kubva kuma wafers ane 6-inch kuenda kuma 8-inch uye 12-inch kunowedzera nzvimbo inoshandiswa ye chip uye kubuda kwe wafer imwe neimwe. Ma wafers makuru, pamwe chete nekufambira mberi mukugadzirwa kwemidziyo senge magadzirirwo e trench-gate uye kutonhora kwemativi maviri, zvinobvumira ma modules ekushanda kwepamusoro nemitengo yakaderera. Kutenderera uku kunokurumidza sezvo mashandisirwo akawanda akadai semotokari dzemagetsi, ma industrial drives, uye masisitimu esimba rinogona kudzokororwa zvichigadzira kudiwa kuri kuramba kuchienderera mberi kwemidziyo yeSiC inoshanda uye yakavimbika.
Kuvimbika uye Mabhenefiti Enguva Refu
Zvishandiso zveSiC hazvingobatsiri chete pakushanda zvakanaka asiwo zvinowedzera kuvimbika uye kusimba. Kufambiswa kwazvo kwekupisa uye voltage yakakwira inobvumira michina kuti ikwanise kutsungirira mamiriro ekushanda akanyanya, kusanganisira kukurumidza kupisa uye voltage yakakwira. Mamodule akavakirwa pazvishandiso zveSiC zvemhando yepamusoro anoratidza hupenyu hwakareba, mwero wekutadza wakaderera, uye kugadzikana kwekushanda kuri nani nekufamba kwenguva.
Mashandisirwo ari kubuda, akadai semagetsi emagetsi ane simba guru, zvitima zvemagetsi, uye masisitimu emagetsi enzvimbo yedata ane simba guru, anobatsirwa nehunhu hwepamusoro hweSiC hwekupisa nemagetsi. Mashandisirwo aya anoda michina inogona kushanda nguva dzose pasi pekumanikidzwa kwakanyanya uku ichichengetedza kushanda kwakanyanya uye kurasikirwa nesimba kushoma, zvichiratidza basa rakakosha re substrate mukushanda kwesystem-level.
Nzira dzeRamangwana: Kuenda kuMamodule eSimba Akangwara uye Akabatanidzwa
Chizvarwa chinotevera chetekinoroji yeSiC chinotarisa pakubatanidzwa kwakangwara uye kugadzirisa masisitimu. Mamodule emagetsi akangwara anobatanidza masensa, maseketi ekudzivirira, uye madhiraivha zvakananga mumodule, zvichiita kuti pave nekutarisa kwenguva chaiyo uye kuvimbika kwakawedzerwa. Nzira dzakasanganiswa, dzakadai sekubatanidza SiC nemidziyo ye gallium nitride (GaN), dzinovhura mikana mitsva yemasisitimu e ultra-high-frequency uye high-efficiency.
Tsvagiridzo iri kutsvagawo hunyanzvi hwepamusoro hweSiC substrate, kusanganisira kurapwa kwepamusoro, manejimendi yekukanganisa, uye dhizaini yezvinhu zvequantum-scale, kuti iwedzere kuvandudza mashandiro. Izvi zvitsva zvinogona kuwedzera mashandisirwo eSiC munzvimbo dzaimbove dzakaganhurirwa nekushomeka kwekupisa nemagetsi, zvichigadzira misika mitsva yemasisitimu emagetsi anoshanda zvakanyanya.
Mhedziso
Kubva pagirazi rekristaro repasi pevhu kusvika pakushandura simba kwakazara, silicon carbide inoratidza kuti sarudzo yezvinhu zvinotungamira sei mashandiro esystem. Zvishandiso zveSiC zvemhando yepamusoro zvinogonesa magadzirirwo emidziyo yepamusoro, zvinotsigira mashandiro emagetsi ane simba rakawanda uye mafrequency akakwira, uye zvinopa kushanda zvakanaka, kuvimbika, uye kubatana padanho resystem. Sezvo kudiwa kwesimba repasi rose kuchikura uye magetsi emagetsi achiva chinhu chikuru mukufambisa, simba rinogona kudzorerwa, uye otomatiki yeindasitiri, zvishandiso zveSiC zvicharamba zvichishanda se tekinoroji yekutanga. Kunzwisisa rwendo kubva pakushandura kuenda pakushandura kunoratidza kuti hunyanzvi hwezvinhu hunoita sediki hunogona sei kuumbazve mamiriro ese emagetsi emagetsi.
