DC Bus Capacitors no IGBT-Based Converters in Traction Apparatus

ʻO ka wehewehe pōkole:

Kāpena kaʻa pahi DC DMJ-MC moʻo

Hana ʻia nā capacitors kiʻiʻoniʻoni metallized i ʻelua kiʻiʻoniʻoni metala me ka kiʻiʻoniʻoni plastik e like me ka dielectric.

Hoʻohana ʻia kahi metallization alumini ʻokiʻoki loa (~ 0.03 μm [2]) i hoʻokahi a i ʻole nā ​​ʻaoʻao ʻelua e lilo i electrodes.

Huahana Huahana

Nā kaha kiʻiʻoniʻoni polypropylene

Paʻa metala polypropylene film dielectric dc capacitors,

Hiki i kēia hoʻonohonoho ke loaʻa i nā waiwai "ho'ōla pono'ī", i ka dielectric breakdowns a i ʻole nā ​​pōkole pōkole ma waena o nā electrodes ʻaʻole pono e alakaʻi i ka luku ʻana i ka ʻāpana.

Me kēia hoʻolālā kumu, hiki ke hana i nā huahana kiʻekiʻe e like me ka "zero defect" capacitors a me ka hana ʻana i nā capacitors ʻeha me nā waiwai capacitance nui (a hiki i 100 μF a ʻoi aku ka nui) i nā hihia liʻiliʻi (high volumetric efficiency) i hoʻohālikelike ʻia me ke kiʻiʻoniʻoni / ke kūkulu ʻia ʻana o ka foil.

He ikaika ka CRE no kona mana R&D, hoʻomohala mākou i kahi capacitor e like me ka capacitance i helu ʻia, ka voltage helu, ka ʻenehana hana, etc.

Hiʻona

1. ʻenehana ʻano maloʻo;

2. Laulā wela ākea;

3. ʻO ka hiki ke pale aku i nā voltage kiʻekiʻe loa;

4. Nā poho uila haʻahaʻa;

5. Hiki ke lawelawe i nā pi'i ki'eki'e a ki'eki'e loa.

Palapala noi

Hoʻopili ʻia nā capacitors kiʻiʻoniʻoni no ka hoʻohana ʻana i nā lako uila i nā ʻano ʻoihana maʻamau a maʻamau: axial, radial, cylindrical, metal case, etc.
