He Tirohanga Hōhonu Hangarau | Me pēhea e taea ai e ngā Pūnga Kiriata DC-Link te Whakatika i ngā Wero o te Ngaohiko me te Pono i roto i ngā Papaaho Puku Hiko 800V?

Kupu Whakataki

I te mea kua rongonui haere ngā tūāpapa hiko-tiketike 800V i roto i ngā waka hiko hou, kei te piki ake te tono a ngā kaitahuri hiko ki ngā āhuatanga auau-tiketike o ngā pūnga DC-Link. Ko ngā pūnga hiko hiko konumohe tuku iho, he mea whakawhāitihia e tō rātou ESR teitei me te urupare auau, ka ngāwari ki te piki haere o te ngaohiko, ka whakawhāiti i te pai o te pūnaha me te aukati i te mahi katoa o ngā taputapu SiC.

Ngā Otinga Pūnga Kiriata YMIN

- Tātari Hangarau Taketake – Nā runga i ō rātou āhuatanga rauemi me te hanganga, he nui te ESR o ngā pūnga hiko konumohe, ā, he iti te auau whaiaro-whakaohooho (tata ki te 4kHz anake). I raro i ngā mahi whakawhiti auau-tiketike, kāore i te rawaka tō rātou kaha ki te mimiti i te au ripo auau-tiketike, ka ngāwari te puta o ngā huringa ngaohiko pahi, ka pā ki te pumau o te pūnaha me te roa o te taputapu hiko. – Ngā Otinga me ngā Painga Tukanga YMIN –Raupapa MDP a YMINKa whakamahia e ngā pūnga kiriata te rauemi kiriata polypropylene whakarewa me te tukanga takai auaha hei whakatutuki i ngā whakapainga mahi e whai ake nei: Ka whakaitihia te ESR ki te taumata milliohm, ka whakaitihia te ngaronga whakawhiti; ka whakanuia te auau oro ki ngā tekau kHz, ka urutau katoa ki ngā whakaritenga tono auau-tiketike o ngā SiC/MOSFET; ā, ko ō rātou painga ko te ngaohiko ātete teitei, te ia turuturu iti, me te roa o te ora, e tino pai ai mō ngā taiao whakahaere ngaohiko-tiketike, auau-tiketike.

Ngā horopaki tono me ngā tauira e taunakitia ana -

Tauira Whakamahinga Noa: E whakamahi ana te tūāpapa taraiwa hiko 800V a tētahi kaihanga waka nui i ngā pūnga MDP-800V-15μF e waru i roto i te ara iahiko DC-Link o te inverter taraiwa matua, ā, ka angitu te whakakapi i ngā pūnga hiko konumohe 22 450V o te otinga taketake. Ka whakaitihia e tēnei te horahanga PCB mā te neke atu i te 50%, ka whakaitihia te tihi ngaohiko pahi mā te 40%, ā, ka whakapai ake i te pai o te tihi pūnaha mā te tata ki te 1.5%. – Ngā Tauira i Manakohia -

Whakamutunga
Ehara i te mea he pūnga hiko mahi-teitei anake te raupapa YMIN MDP engari he kaiwhakahaere hiko matua hoki i roto i ngā pūnaha hiko-teitei, auau-teitei. Ka taea e ia te āwhina i ngā kaihangarau ki te aro nui ki ngā wero hoahoa me te whakapai ake i te mahi me te pono o te pūnaha.
