Izinhlelo zikagesi ezisebenzisa amandla emotweni kagesi (i-EV) zinezinhlobo eziningi zama-capacitor.
Kusukela kuma-capacitor e-DC-link kuya kuma-capacitor okuphepha kanye nama-capacitor angenamsebenzi, lezi zingxenye zidlala indima ebalulekile ekuzinziseni nasekuvikeleni ama-elekthronikhi ezicini ezifana nokukhuphuka kwamandla kagesi kanye nokuphazamiseka kwamandla kagesi (i-EMI).
Kunezinhlobo ezine eziyinhloko zama-inverter okudonsa, anomehluko osuselwa kuhlobo lokushintsha, i-voltage kanye namazinga. Ukukhetha i-topology efanele kanye nezingxenye ezihlobene kubalulekile ekwakhiweni kwama-inverter okudonsa ahlangabezana nezidingo zokusebenza kahle kanye nezindleko zesicelo sakho.
Njengoba kushiwo, kunezinhlobo ezine ze-topology ezisetshenziswa kakhulu kuma-inverters e-EV traction, njengoba kuboniswe kuMfanekiso 2.

I-Level Topology equkethe i-650V IGBT switch
-
I-Level Topology equkethe i-650V SiC MOSFET switch
-
I-Level Topology equkethe i-switch ye-1200V SiC MOSFET
-
I-Level Topology equkethe i-650V GaN Switch
Lezi zinhlobo ze-topologies zihlukaniswa zibe izingxenye ezimbili: Izitimela zamandla ezingama-400V kanye nezitimela zamandla ezingama-800V. Phakathi kwalezi zinhlobo ezimbili ze-topologies, kuvame kakhulu ukusebenzisa izinhlobo ze-topologies “ezinezinga ezimbili”. Izinhlobo ze-topologies “ezinezinga eziningi” zisetshenziswa ezinhlelweni zamandla aphezulu njengezitimela zikagesi, ama-tramway kanye nemikhumbi kodwa azithandwa kakhulu ngenxa yezindleko eziphakeme kanye nobunzima.

Ama-Capacitors e-Snubber– Ukunciphisa i-voltage kubalulekile ukuvikela amasekethe ekukhuphukeni okukhulu kwe-voltage. Ama-snubber capacitors axhuma ku-node yokushintsha yamandla aphezulu ukuvikela ama-electronics ekukhuphukeni kwe-voltage.

Ama-Capacitor e-DC-Link- Ezinhlelweni ze-EV, Ama-capacitor e-DC-link asiza ekunciphiseni imiphumela ye-inductance kuma-inverters. Asebenza futhi njengezihlungi ezivikela izinhlelo ze-EV ezingaphansi kwamandla kagesi, ukukhuphuka kwamandla kagesi kanye ne-EMI.
Zonke lezi zindima zibaluleke kakhulu ekuphepheni nasekusebenzeni kwama-inverter okudonsa, kodwa ukwakheka kanye nezincazelo zala ma-capacitor kuyashintsha ngokusekelwe ekutheni ukhetha yiphi i-topology ye-inverter yokudonsa.
