Ngā Rerekētanga i waenga i ngā BJT me ngā MOSFET i roto i ngā Pūnaha Whakahaere Pūhiko (BMS)

1. Ngā Pūwhakawhiti Hononga Pirau (BJT):

(1) Hanganga:He taputapu haurua-irahiko ngā BJT me ngā irahiko e toru: te turanga, te kaituku, me te kaikohi. Ko te nuinga o ēnei e whakamahia ana mō te whakanui, te whakawhiti rānei i ngā tohu. Me whai iahiko iti ki te turanga ngā BJT hei whakahaere i te rere iahiko nui ake i waenga i te kaikohi me te kaituku.

(2) Te mahi i roto i te BMS: In BMSI roto i ngā tono, ka whakamahia ngā BJT mō ō rātou kaha whakanui iahiko. Ka āwhina rātou ki te whakahaere me te whakahaere i te rere o iahiko i roto i te pūnaha, kia tika ai te utu me te tuku i ngā pākahiko me te tuku atu i te hiko me te haumaru.

(3) Ngā Āhuatanga:He nui te pikinga o te iahiko o ngā BJT, ā, he tino whai hua i ngā tono e hiahia ana kia tika te whakahaere i te iahiko. He tairongo ake rātou ki ngā āhuatanga wera, ā, ka nui ake te marara o te mana i ērā o ngā MOSFET.

2. Ngā Pūwhakawhiti Pānga-Whānui-Waikura-Haumaru (MOSFET):

(1) Hanganga:He taputapu haurua-irahiko ngā MOSFET, e toru ngā pito: te kuaha, te pūtake, me te rerenga hiko. Ka whakamahia e rātou te ngaohiko hei whakahaere i te rere o te iahiko i waenga i te pūtake me te rerenga hiko, ā, he tino whai hua ēnei i roto i ngā tono whakawhiti.

(2) Mahi i roto iBMS:I roto i ngā tono BMS, he maha ngā wā ka whakamahia ngā MOSFET nā te mea he pai te whakawhiti hiko. Ka taea e rātou te tahuri me te whakaweto tere, ka whakahaere i te rere o te iahiko me te iti o te ātete me te ngaronga hiko. Nā tēnei ka pai rātou mō te tiaki i ngā pākahiko mai i te utu nui rawa, te tukunga nui rawa, me ngā ara iahiko poto.

(3) Ngā Āhuatanga:He teitei te aukati whakauru o ngā MOSFET, ā, he iti te ātete-ki-te-whakaū, nā reira he tino whai hua me te iti ake o te marara wera ki te whakaritea ki ngā BJT. He tino pai mō ngā tono whakawhiti tere-teitei me te tino whai hua i roto i te BMS.

Whakarāpopototanga:

• Ngā BJThe pai ake mō ngā tono e hiahia ana ki te whakahaere iahiko tika nā te mea he nui te whakanui iahiko.
• Ngā MOSFEThe pai ake mō te whakawhiti tere me te whai hua me te iti o te marara wera, he mea tino pai mō te tiaki me te whakahaere i ngā mahi pākahiko i rotoBMS.
