Pūnaha hiko whakawhiti PFC teitei

Ko te PFC te tikanga o te whakatikatika ira mana, e whakamahia ana hei whakaahua i te whai huatanga o te whakamahinga o te pūngao hiko e ngā hua hiko. Ka teitei ake te ira mana, ka teitei ake te whai huatanga o te whakamahinga o te pūngao hiko.

E rua ngā momo PFC: te PFC kore mahi me te PFC hohe. Ko te PFC kore mahi te tikanga utu ine hiko hei whakaiti i te rerekētanga ā-wāhanga i waenga i te iahiko taketake me te ngaohiko o te tāuru AC hei whakapai ake i te tauwehe mana, engari kāore i te tino teitei te tauwehe mana o te PFC kore mahi, ā, ka eke noa ki te 0.7 ~ 0.8; Ko te PFC hohe he mea tito mai i te ine hiko, te kaha me ngā wāhanga hiko, ka eke ki te 0.99. He iti, ā, ka taea te whakatutuki i te tauwehe mana teitei, engari he nui ake te utu i te PFC kore mahi.

He maha ngā wā ka whakamahia te PFC hei pūtake hiko hohe i roto i te PC, ā, ko ngā āhuatanga o te PFC e whai ake nei:

1) Ka taea te whakamahi i te ngaohiko tāuru mai i te 90V ki te 270V;

2) He teitei ake te tauwehenga mana raina i te 0.98, ā, he iti te mate me te tino pono;

3) Ka taea hoki te whakamahi i te PFC o te IC hei puna hiko āwhina, nō reira kāore e hiahiatia te whakawhiti hiko tūtatari i te nuinga o te wā i te whakamahinga o te ara iahiko PFC hohe;

4) Kāore te putanga e rerekē ana me te ngaohiko tāuru, nō reira ka taea te whiwhi i tētahi ngaohiko putanga tino pumau;

5) He tino iti te ngaru hiko DC putanga o te PFC hohe, ā, he ngaru sine 100Hz / 120Hz (e rua te auau hiko). Nō reira, kāore e hiahiatia he pūnga tātari kaha nui mō te pūtake hiko e whakamahi ana i te PFC hohe.

Ko te PFC hohe he mea tito mai i te inductance, te capacitance me ngā wāhanga hiko. He iti tōna rōrahi. Ka whakatikatika i te āhua o te iahiko mā te IC motuhake hei utu i te rerekētanga ā-wāhanga i waenga i te iahiko me te ngaohiko. Ka taea e te PFC hohe te whakatutuki i te tauwehenga mana teitei - neke atu i te 98% te nuinga, engari he nui hoki te utu. Hei tāpiri, ka taea hoki te whakamahi i te PFC hohe hei pūhiko āwhina. Nō reira, i te whakamahinga o te ara iahiko PFC hohe, he maha ngā wā kāore e hiahiatia te whakawhiti tūtatari, ā, he tino iti te ripple o te ngaohiko DC putanga o te PFC hohe. Kāore e hiahiatia e tēnei pūhiko he pūhiko tātari kaha nui.

Nō nā tata nei mātou i whakarewa ai i ngā pūhiko whakawhiti 2000W me te 3000W me te PFC. He tino pai te utu. He iti ake te utu i te pūhiko kotahi i te mākete, ā, he tino pumau te mahi. Ki te hiahia koe ki tēnei, tēnā whakapā mai. Ngā mihi!
