He aha nā ʻano 4 o Optocouplers: Revolutionizing Electrical Isolation

E ʻimi ana i nā noi like ʻole o nā Optocouplers i ka ʻenehana hou

I loko o ka honua e ulu wikiwiki nei o ka uila, ua puka mai nā optocouplers ma ke ʻano he mea hoʻololi pāʻani i ka hōʻoia ʻana i ka hoʻokaʻawale uila hilinaʻi. I kēia lā, ʻimi mākou i nā ʻano optocoupler ʻehā e hana nei i ka wā e hiki mai ana o nā ʻoihana like ʻole, mai ka automotive a hiki i ke kelepona.

 

1. Photo-Transistor Optocouplers: Hoʻohana nui ʻia kēia mau optocouplers i nā noi kahi e koʻikoʻi ai ka hoʻouna ʻana i ka hōʻailona kiʻekiʻe. Hoʻololi ke ʻano transistor kiʻi i ka mālamalama i hōʻailona uila, a laila hoʻonui ʻia, e kūpono ia no nā noi e like me ka mana kaʻa a me ka hoʻololi ʻana i nā lako mana.

 

2. Photo-Interrupter Optocouplers: Loaʻa maʻamau i nā mea hana o kēlā me kēia lā e like me nā mea paʻi a me nā scanners, hoʻolālā ʻia nā optocoupler photo-interrupter e ʻike i ke alo a i ʻole ka ʻole o kahi mea. Aia lākou i kahi LED infrared a me kahi photodiode, e hoʻomaʻamaʻa iā lākou no ka ʻike a me ka helu ʻana i nā noi.

 

3. Photo-TRIAC Optocouplers: He kūpono no ka hoʻomāmā ʻana i nā kukui a me ka hoʻomalu ʻana i ka mana AC i nā mea hana, hāʻawi ke ʻano kiʻi-TRIAC o nā optocoupler i ka pale ʻana i ka leo kiʻekiʻe a me ka hoʻokaʻawale uila. ʻO kēia ka mea i koho maikaʻi ʻia no nā noi relay solid-state i ka HVAC a me nā ʻoihana ʻoihana.

 

4. Digital Optocouplers: E like me ka inoa e hōʻike nei, ua hoʻolālā pono ʻia kēia mau optocouplers no ka lawe ʻana i nā hōʻailona kikohoʻe. Hāʻawi lākou i ka hōʻole leo maikaʻi a hoʻohana nui ʻia i ka kamaʻilio ʻikepili, nā ʻōnaehana mana microprocessor, a me ka hoʻokaʻawale logic digital.

 

"Loaʻa i kēlā me kēia ʻano optocoupler kona mau hiʻohiʻona kūʻokoʻa a me nā noi, e lilo ia i mea nui i nā ʻōnaehana uila hou," wahi a Kauka Johnathan Lee, he loea alakaʻi i ka optoelectronics. "ʻAʻole i hoʻomaikaʻi wale ka hoʻomohala ʻana o kēia mau optocoupler i ka hana a me ka hilinaʻi o nā mea uila akā ua hōʻoia pū kekahi i ka hana palekana ma ka pale ʻana i ka hoʻopili uila."

 

Ua piʻi aʻe ke koi no nā optocouplers i nā makahiki i hala iho nei, i alakaʻi ʻia e ka ulu nui o ka pono no nā mea uila uila a paʻa. Ke koi mau nei nā mea hana i nā palena o ka ʻenehana optocoupler e hoʻokō i nā koi e ulu nei o nā ʻoihana like ʻole.

 

"Ua lilo nā Optocoupler i mea nui o ko mākou ola i kēlā me kēia lā, e hana pinepine ana ma hope o nā hiʻohiʻona e hōʻoia i ka holo mālie o nā mea uila," wahi a Maria Thompson, Luna Nui o kahi hui optoelectronics alakaʻi. "ʻO kā mākou kūpaʻa i ka hana hou a me ka maikaʻi e hoʻomau i ka holomua o ka ʻenehana optocoupler."

 

Ke hilinaʻi nui nei ka honua i nā ʻōnaehana uila maʻalahi, ʻaʻole hiki ke hoʻonui ʻia ke kuleana o nā optocouplers i ka hōʻoia ʻana i ka hoʻokaʻawale uila a me ka hana hilinaʻi. Me nā ʻano optocoupler ʻehā e mālama ana i nā noi like ʻole, ʻoi aku ka mālamalama o ka wā e hiki mai ana o ka uila a ʻoi aku ka kaʻawale ma mua o ka wā ma mua.
