Ke hilinaʻi nei ka honua o ka uila i nā ʻano like ʻole, e pāʻani ana kēlā me kēia i kahi kuleana koʻikoʻi. Ma waena o kēia mau mea, kū i waho nā diodes no ko lākou hiki ke hoʻomalu i ke kahe o ka uila. I kēia lā, ʻimi mākou i kahi ʻano kikoʻī - ka Schottky diode, kahi hui kūʻokoʻa o ka metala a me ka semiconductor me ka nui o nā noi waiwai.
Ka hoomaopopo ana i ka Schottky Diode
'A'ole like me ka pn junction diode ma'amau, 'o ka Schottky diode ka hui 'ana ma waena o ka metala a me ka semiconductor. Hoʻokumu kēia i kahi pale Schottky, kahi ʻāina kahi i kaupalena ʻia ai ke kahe electron. Ke hoʻohana ʻia ka volta ma ka ʻaoʻao i mua (ma ka ʻaoʻao metala), lanakila nā electrons i ka pale a holo maʻalahi kēia manawa. Eia nō naʻe, ʻo ka hoʻohana ʻana i ka volta hoʻohuli e hana i kahi pale ikaika, e pale ana i ke kahe o kēia manawa.
Hoailona a me na ano
Ua like ka hōʻailona o ka diode Schottky me ka diode maʻamau me ka laina i hoʻokaʻawale ʻia i ka huinakolu e kuhikuhi ana i ka pahu kūpono. Ua like kona ano VI me ka pn junction diode, aka me ke ano nui: he ha'aha'a ha'aha'a ha'aha'a iho i mua, ma waena o 0.2 a 0.3 volts. ʻO kēia ka unuhi i ka hoʻohaʻahaʻa i ka nalowale o ka mana i ka wā o ka hana.
Ke Kumu Hana
ʻO ke kumu kumu ma hope o ka hana a Schottky diode aia i ka ʻokoʻa o ka ikehu o nā electrons i nā mea like ʻole. Ke hoʻopili ʻia kahi metala a me ka semiconductor ʻano n, kahe nā electrons ma waena o ka hui ma nā ʻaoʻao ʻelua. ʻO ka hoʻohana ʻana i ka volta i mua e hoʻoikaika i ke kahe i ka semiconductor, hiki ke ʻae i kēia manawa.
Nā noi o ka Schottky Diode
Loaʻa nā diodes Schottky iā lākou iho i nā noi uila ma muli o ko lākou mau waiwai kūʻokoʻa:
RF Mixers and Detectors: ʻO kā lākou wikiwiki hoʻololi kūʻokoʻa a me ka hiki ke kiʻekiʻe kiʻekiʻe e hoʻolilo iā lākou i mea kūpono no nā noi lekiō (RF) e like me nā mea hui pū diode.
Nā Mana Hoʻoponopono: ʻO ka hiki ke mālama i nā au kiʻekiʻe a me nā voltages me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e hoʻoponopono iā lākou i nā mana hoʻoponopono, e hōʻemi ana i ka nalowale o ka mana i hoʻohālikelike ʻia me nā diodes junction.
Ka Mana A I ʻole Kaapuni: Ma nā kaʻapuni kahi e hoʻokele ai nā lako mana ʻelua i kahi ukana (e like me ke kākoʻo pākaukau), pale ʻo Schottky diodes i ke kahe hou ʻana i hoʻokahi lako mai kekahi.
Nā noi ʻana o ka lā: Hoʻopili pinepine ʻia nā panela solar i nā ʻeke i hoʻihoʻi hou ʻia, ʻo ia hoʻi he lead-acid. No ka pale ʻana i ke kahe hou ʻana i loko o nā keena lā i ka pō, hoʻohana ʻia nā diodes Schottky i kahi hoʻonohonoho bypass.
ʻO nā pono a me nā pōʻino
Hāʻawi ʻo Schottky diodes i nā pono he nui:
Ka Haʻahaʻa Haʻahaʻa: ʻO ka ʻāpana hoʻohaʻahaʻa haʻahaʻa ka hopena i ka capacitance haʻahaʻa, e kūpono ana iā lākou no nā noi kiʻekiʻe.
Hoʻololi wikiwiki: ʻO ka hoʻololi wikiwiki ʻana mai nā mokuʻāina a i waho e hiki ai ke hana wikiwiki.
Kiʻekiʻe Kiʻekiʻe o kēia manawa: ʻO ka ʻāpana liʻiliʻi liʻiliʻi e hiki ai iā lākou ke mālama i nā density kiʻekiʻe o kēia manawa.
ʻO ka Voltage Huli Haʻahaʻa: ʻO ka hāʻule ʻana o ka uila i mua o 0.2 a 0.3 volts he haʻahaʻa loa ma mua o nā diodes junction.
Eia nō naʻe, aia kekahi drawback nui:
Kiʻekiʻe Reverse Leakage Current: Schottky diodes e hōʻike ana i ka ʻoi aku ka kiʻekiʻe o ka leakage huli ʻana i hoʻohālikelike ʻia me nā diodes junction. Hiki ke pilikia kēia i kekahi mau noi.
Ka hopena
ʻO ka diode Schottky, me kāna hui metala-semiconductor kū hoʻokahi, hāʻawi i kahi hui waiwai o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ka wikiwiki hoʻololi wikiwiki, a me ka hiki ke lawelawe i kēia manawa. ʻO kēia ka mea i hiki ʻole ke hoʻololi ʻia i nā ʻāpana uila like ʻole, mai nā lako mana a i nā ʻōnaehana ikehu lā. Ke hoʻomau nei ka hoʻomohala ʻana o ka ʻenehana, ʻo ka diode Schottky e paʻa mau i ka hana pono i ka ʻoihana uila.
