Pono ʻia kahi alahaka thyristor rectifier ʻekolu-phase e hoʻomalu i kahi kaʻa DC.He mea nui ka mea kūpono e hōʻoia i ka hana paʻa o ka mea hoʻomaka palupalu e hoʻokele i ka kaʻa a pono e koho ʻia e kūlike me ka waiwai o ka kaʻa a me ke koi o ka ʻōnaehana.Hāʻawi ʻia ke kumu koho ma lalo nei:

1. Kūlana: Volta komo V_laina=380V (3N 50Hz), hoʻopuka DC i kēia manawa I_d= 3600A, ʻo ke ʻano hoʻoluʻu o thyristor ʻo ka hoʻoluʻu ʻana i ka ea, ka wela o ke kaiapuni T_A= 40 ℃, ka piʻi ʻana i makemake ʻia I_TSM=20KA.

2.Selection o ka uila: peak waiwai o ka helu laina laina

V_D(max)=*V_I= * 380 = 537V, ua manaʻo ʻia ka coefficient anti-impact e like me 2.5, ʻo ke kumu e helu ai i ka māka volta: V_DSM≥537V*2.5= 1343V, pela

V_DSM= V_RSM= 1400V.

3.Selection o kēia manawa: ma muli o ka outline o thyristor mea okoa me ka okoa o keia manawa, no laila mākou e helu i ka pono o keia manawa waiwai mai ka thyristor me Vrrm=1400V.I_d=3600A, ka awelika o ke au i hele ma kēlā me kēia thyristor I_T=1200A, ke au i helu ʻia o thyristor I_T(AV)=1200A*2.5=3000A.

4. E koho ʻia ka heatsink hoʻoheheʻe ea e like me ka outline o thyristor.

5. Pono e koho ʻia ka thyristor a me ka heatsink e kūʻē i ka noi a me nā koi kikoʻī o ka ʻōnaehana mana kaʻa.ʻO ka thyristor control phase a me ka heatsink i hana ʻia e Jiangsu Yangjie Runau Semiconductor Co ua hoʻohui nui ʻia me ke kūlana o ka ʻenehana no ka hana ʻana i ka mana semiconductor mana kiʻekiʻe.Hoʻohana nui ʻia ia i ka noi hoʻokele kaʻa.E ʻoluʻolu e kelepona i kā mākou ʻenehana loea e koho i ka mea kūponokouristoraheatsinkno ka hana maikaʻi loa o kāu noi.
