Amasistimu kagesi kagesi emotweni kagesi (EV) afaka ama-capacitor anhlobonhlobo.
Kusukela kuma-DC-link capacitor kuya kuma-capacitor okuphepha nama-snubber capacitor, lezi zingxenye zidlala indima ebalulekile ekusimamiseni nasekuvikeleni izinto zikagesi ezicini ezifana nama-voltage spikes kanye ne-electromagnetic interference (EMI).
Kunezihloko ezine eziyinhloko zama-inverter e-traction, anomehluko osuselwe kuhlobo lokushintshwa, i-voltage kanye namazinga.Ukukhetha i-topology efanele kanye nezingxenye ezihlobene nakho kubalulekile ekuklameni ama-inverter ahambisanayo nokusebenza kahle kohlelo lwakho nezidingo zezindleko.
Njengoba kushiwo, kukhona ama-topology amane asetshenziswa kakhulu kuma-inverter e-EV traction, njengoba kukhonjisiwe kuMfanekiso 2.:
-
I-Level Topology equkethe iswishi engu-650V IGBT
-
I-Level Topology equkethe iswishi engu-650V SiC MOSFET
-
I-Level Topology equkethe iswishi ye-1200V SiC MOSFET
-
I-Level Topology efaka i-650V GaN switch
Lawa ma-topology awela kumasethi angaphansi amabili: 400V Powertrains & 800V Powertrains.Phakathi kwamasethi angaphansi amabili, kuvame kakhulu ukusebenzisa izihloko eziphezulu ze-“2-level”.Ama-topology “amazinga amaningi” asetshenziswa ezinhlelweni zamandla kagesi aphezulu njengezitimela zikagesi, amathilamu esitimela nemikhumbi kodwa awadumile ngenxa yezindleko eziphezulu nokuba yinkimbinkimbi.
-
Ama-Snubber Capacitors- Ukucindezelwa kwamandla kagesi kubalulekile ukuvikela amasekhethi kuma-voltage spikes amakhulu.Ama-Snubber capacitor axhumeka ku-node yokushintsha yamanje ephezulu ukuze avikele ama-electronics kuma-voltage spikes.
-
I-DC-Link Capacitors- Kuzinhlelo zokusebenza ze-EV, Ama-capacitor e-DC-link asiza ukususa imiphumela ye-inductance kuma-inverters.Zisebenza njengezihlungi ezivikela amasistimu angaphansi we-EV kuma-voltage spikes, ama-surges kanye ne-EMI.
Zonke lezi zindima zibaluleke kakhulu ekuphepheni nasekusebenzeni kwama-inverter ama-traction, kodwa ukwakheka kanye nokucaciswa kwalawa ma-capacitor kuyashintsha ngokusekelwe ekutheni ukhetha yiphi i-traction inverter topology.
