He whānuitanga o ngā pūnga iahiko kei roto i ngā pūnaha hiko mana i roto i tētahi waka hiko (EV).
Mai i ngā pūnga hiko DC-hononga ki ngā pūnga hiko haumaru me ngā pūnga hiko snubber, he mea nui ēnei wāhanga ki te whakau me te tiaki i ngā hiko mai i ngā āhuatanga pēnei i ngā pikinga ngaohiko me te pokanoa hikohiko (EMI).
E whā ngā āhua matua o ngā kaitahuri hiko, me ngā rerekētanga i runga i te momo pana, te ngaohiko me ngā taumata. He mea nui te whiriwhiri i te āhua tika me ngā wāhanga e pā ana ki te hoahoa i ngā kaitahuri hiko e tutuki ai ngā whakaritenga whai hua me te utu o tō tono.
E ai ki te kōrero, e whā ngā momo āhua e whakamahia whānuitia ana i roto i ngā inverters EV traction, e whakaaturia ana i te Pikitia 2:
-
Taumata Taumata e whakaatu ana i te pana IGBT 650V
-
Taumata Taumata e whakaatu ana i te pana MOSFET 650V SiC
-
Taumata Taumata e whakaatu ana i te pana MOSFET 1200V SiC
-
Taumata Taumata e whakaatu ana i te Whakawhiti GaN 650V
E rua ngā wāhanga o ēnei āhuarangi: Ngā Rerewē Hiko 400V me Ngā Rerewē Hiko 800V. I waenganui i ngā wāhanga e rua, he mea noa ake te whakamahi i ngā āhuarangi "taumata-2". E whakamahia ana ngā āhuarangi "taumata-maha" i roto i ngā pūnaha hiko teitei ake pērā i ngā tereina hiko, ngā tereina me ngā kaipuke engari kāore i te tino rongonui nā te utu nui me te uaua.
-
Ngā Pūngao Snubber– He mea nui te pehi hiko hei tiaki i ngā ara iahiko mai i ngā pikinga hiko nui. Ka hono ngā pūnga hiko snubber ki te pūnga whakawhiti hiko-teitei hei tiaki i ngā hiko mai i ngā pikinga hiko.
-
Ngā Pūngao Hononga-DC– I roto i ngā tono EV, Ka āwhina ngā pūnga hiko DC-hononga ki te whakakore i ngā pānga o te inductance i roto i ngā inverters. Ka mahi anō hoki rātou hei tātari hei tiaki i ngā pūnaha EV mai i ngā pikinga ngaohiko, ngā ngaru me te EMI.
He mea tino nui ēnei mahi katoa ki te haumaru me te mahi a ngā inverters traction, engari ka rerekē te hoahoa me ngā whakaritenga o ēnei pūnga i runga i te āhua o te inverter traction e whiriwhiria e koe.
