40kW SiC yakakwirira kushanda zvakanaka DC EV Kuchaja Module

SiC yakakwirira yekuchaja module inogoneka zvakanyanya sezvo kudiwa kweiyo yakakwira voltage yekuchaja kuri kuwedzera Kutevera nyika yePorsche yekutanga ye800V yakakwira-voltage papuratifomu modhi Taycan munaGunyana 2019, makambani makuru eVV akaburitsa 800V yakakwira-voltage inokurumidza-kuchaja modhi, seHyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, nezvimwe. .Zvese zvinounzwa kana kuve nekugadzirwa kwakawanda mumakore maviri aya. 800V kukurumidza kuchaja iri kuve iyo huru mumusika; CITIC Securities inofanotaura kuti panosvika 2025, nhamba yemhando yepamusoro-voltage yekuchaja inokurumidza kusvika 5.18 miriyoni, uye chiyero chekupinda chichawedzera kubva ikozvino zvishoma pamusoro pe10% kusvika 34%. Iri richava iro rekutanga simba rekufambisa mukukura kweiyo yakakwira-voltage inokurumidza kuchaja musika, uye makambani ekumusoro anotarisirwa kubatsirwa zvakananga kubva pazviri. Zvinoenderana neruzivo rweveruzhinji, iyo yekuchaja module ndiyo yakakosha chikamu chemurwi wekuchaja, inoverengera nezve 50% yemutengo wakazara wemurwi wekuchaja; pakati pavo, iyo semiconductor simba mudziyo wekushandisa inoverengera makumi matatu muzana yemutengo wekuchaja module, kureva kuti, iyo semiconductor simba module inoverengera inosvika gumi neshanu muzana yemari yekuchaja murwi, inova mubatsiri mukuru weketani mukuvandudza kwemusika wekuchaja mirwi. . Parizvino, magetsi emagetsi anoshandiswa mukuchaja mirwi anonyanya kunzi IGBTs uye MOSFETs, ese ari maSi-based zvigadzirwa, uye kuvandudzwa kwekuchaja mirwi kuDC yekuchaja nekukurumidza kwaisa pamberi pepamusoro zvinodiwa zvemagetsi emagetsi. Kuti uite kuchaja kwemota nekukurumidza sekuwedzera mafuta pachiteshi chegesi, vagadziri vemotokari vari kushingaira kutsvaga zvinhu zvinogona kuvandudza kushanda zvakanaka, uye silicon carbide parizvino ndiyo mutungamiri. Silicon carbide ine mabhenefiti ekupisa tembiricha kuramba, kukwirira kupikisa, simba rakawanda, nezvimwe, izvo zvinogona kuvandudza simba rekushandura simba uye kuderedza chigadzirwa. Mota zhinji dzemagetsi dzinoshandisa pa-board AC kuchaja zvirongwa, izvo zvinofanirwa kutora maawa akati wandei kuti zvizadzise kuchaja. Kushandisa simba repamusoro (senge 30kW uye pamusoro) kuona nekukurumidza kuchaja kwemotokari dzemagetsi kwave kunotevera kwakakosha dhizaini yekuchaja mirwi. Pasinei nemabhenefiti ane masimba makuru ekuchaja mirwi, inounzawo matambudziko mazhinji, akadai: kudiwa kwekuona masimba epamusoro-soro ekuchinja-frequency mashandiro, uye kupisa kunokonzerwa nekurasikirwa kwekutendeuka. Nekudaro, SiC MOSFET uye zvigadzirwa zve diode zvine hunhu hwekukwirisa voltage kuramba, kukwira kwekushisa kwekushisa, uye kukurumidza kushandura frequency, iyo inogona kushandiswa nemazvo mukuchaja mirwi module. Zvichienzaniswa neakare silicon-based midziyo, silicon carbide modules inogona kuwedzera kubuda kwesimba rekuchaja mirwi neinoda kusvika 30%, uye kuderedza kurasikirwa nekusvika makumi mashanu%. Panguva imwecheteyo, silicon carbide zvishandiso zvinogona zvakare kuwedzera kugadzikana kwekuchaja mirwi. Pakuchaja mirwi, mutengo uchiri chimwe chezvinhu zvakakosha zvinotadzisa budiriro, saka kuwanda kwesimba rekuchaja mirwi kwakakosha, uye michina yeSiC ndiyo kiyi yekuwana yakakwira simba density. Seyakakwira-voltage, yakakwirira-kumhanya, uye yakakwira-ikozvino mudziyo, silicon carbide zvishandiso zvinorerutsa dhizaini yeDC pile yekuchaja module, kuwedzera iyo unit simba nhanho, uye zvakanyanya kuwedzera simba density, inovhura nzira yekudzikisa system mari yemurwi wekuchaja. Kubva pamaonero emutengo wenguva refu uye nekushandisa zvinogoneka, yakakwirira-simba yekuchaja mirwi uchishandisa SiC zvishandiso zvinounza muhombe mikana yemusika. Sekureva kweCITIC Securities data, parizvino, mwero wekupinda kwesilicon carbide zvishandiso mune nyowani simba mota yekuchaja mirwi ingori gumi muzana, iyo inosiyawo nzvimbo yakafara yeakakwira-simba rekuchaja mirwi. Semutengesi anotungamira muDC yekuchaja indasitiri, MIDA Power yakagadzira uye yakaburitsa iyo yekuchaja module ine yakanyanya simba density, yekutanga IP65 yekudzivirira level yekuchaja module ine yakazvimirira air duct tekinoroji. Nechikwata chakasimba cheR&D uye musimboti wakanangana nemusika, MIDA Simba yakazvipira kushanda nesimba uye nekubudirira kugadzira iyo 40kW SiC yepamusoro yekuchaja module. Nekufemereka kwepamusoro-soro kunopfuura 97% uye super wide epput voltage range kubva pa150VDC kusvika 1000VDC, iyo 40kW SiC yekuchaja module inosangana dzinenge dzese mazinga ekuisa munyika apo ichichengetedza simba zvakanyanya. Nekukurumidza kukura kwenhamba yekuchaja mirwi, zvinotendwa kuti SiC MOSFETs, uye MIDA Power 40kW SiC yekuchaja module ichave yakawanda uye inowanzoshandiswa mukuchaja murwi inoda yakakwirira simba density mune ramangwana.
