Electronically lāʻau kukui: diode a me ka triode

E ka kamailio e pili ana i ka electronically lāʻau kiwikā.

He aha ka ka electronically lāʻau kukui?

Electronically-lāʻau kukui - ka pou nā mīkini home me ka kekahi helu o nā uila aʻa lolo i ka uilaʻikena wale nō i loko o kekahi ao ao. Mai ka helu o nā uila aʻa lolo hilinaʻi nui ma ka inoa o ke kukui: diode (elua nā uila aʻa lolo), he triode (ekolu nā uila aʻa lolo), pentode (elima nā uila aʻa lolo), etc. Ua hoʻohana 'ia i loko o uila' enekinia, uilaʻoe, ka mana a me ka nui no hoi na hana kamaʻilioʻana, e rectify i ka alternating uila he .. like me lakou aloha ia i kaʻikena alapine, hana like me ka mīkini hopu ka mea hewa a me ka OIeEOEIeAeEIIe, i ka mana koʻikoʻi a hanohano. Oe i ike i ke kumu aia no he diode a me ka triode? Ke hoomau aku i ka hemahema i keia nahā i.

diode

A diode mea he electronically lāʻau kukui i loko i loaʻa nō nā nā uila aʻa lolo. Diodes a me transistors o kekahi Lako ke keʻena o ka helu o nā uila aʻa lolo, e hoomanao i kēia. Ma ke kumu o physical kumu, ua puʻunaueʻia ka manaʻo o ko lākou functionality i loko o ka hoailona ia mea (pakahi, kela mea keia mea? Ueo ua puunaueia i ka helu o ka iiaciiie? Ueo):

1. Ka pila holo. Hoʻohana 'ia no ka rectification. I ka enaena, i ka makemake ana wela o ka cathode (ka wā malaila mea he thermoelectric ea puka) iiaeaaony i ka anode pili i ka cathode anakahi uila mea maikaʻi. A laila, i kekahi hapa o ka hookuuia electrons kuhikuhi i ka anode, a me ka diodeʻikena ua hana. Inā keia 'ole e hana, a laila, e hoʻi i ka electrons i ka cathode.

2. Hookuuia. Hoʻohana 'ia no ka nui mana amplifiers a noaaeeecaoee o nui aʻo nui. Ho i kekahi cathode a me ka anode e hoonoho iho i loko o ka inert kinoea make a me ke kinoea ukuhiia ma lalo o kekahi o kekahi puʻe.

3. Mea uholo uila. Hiki noi, ua loa like. He manao maalea ma i ka rectified uila hoʻololi, a ma laila nō nā mawaho auaiaea. Like rectifying uila hoʻololi mea he pn huina, he mea uholo uila-metala Hoʻokaʻaʻike paha giperperehoda.

triode

Haʻalele diode, triode, koe wale no ka anode a me ka cathode, a ua nui ka mana hoʻomalu ma'ūholo uila, a ua kapaʻia he makaʻaha. Aia ma waena o ka anode, a me ka cathode e mana maka aha e leie aku ka kukui huina'ine kahe ma ke hoʻololi i ka nui a me ka polarity o ke anakahi uila ma waena o ka maka aha a me ka cathode. He no ka mea, o keia hiki ua kapaia maka aha hooponopono.

Upena, ma ka hapanui o na hihia, o ka helix o lahilahi uea a poai puni i ka cathode. Paka ia mai nikala, molybdenum, kā lākou oka a pau, a me ka tantalum, a me ka tungsten. I ka lalo o ka Loaʻaʻia o ka maka aha, ua ka nui hana e e ka huina'ine hele i ke kula. Ma lalo o kekahi hopena maikaʻi 'aiee o ke anakahi uila,ʻaʻohe huina'ine eʻaʻole e hiki ke hooki aku i ka maka aha kahua, a me ka anode pono o ka pākali hoʻolele e e Aʻohe. Triols mea pinepine hoʻohana e hoʻonui i ka peahi ana mai, i ka wa e loaa kukuna kedera.

mea hiki ana

Ke pākali hoʻolele a me ka diode, ua 'ā ka qualitative mua aku na ke kālaikūlohea o lākou i ke kūpono' ana o na mea a pau i ka mea i pili me ka uila. He paʻakikī e noonoo ai i na ole radios, kīwī, kamepiula 'ē aʻe, nā kelepona, a ua nui no hoi na mea a pau. Diodes a me transistors i hoʻohana ole wale i ka nui-unahiʻole, i? Iecaianoaaiiie, akā, no hoi ma ka Radio amateurs a me ka Radio uilaʻoe i loko o ko lākou hale ho okolohua. He paʻakikī e noonoo ai i na ka holomua i paiia kaapuni papa, a e mālama i ka luna 'enehana, a ma a ma laila e e electronically lāʻau kukui. Diodes a transistors i ka loa laulā huahelu o ka palapala noi, no laila, i ke alo o kekahi o kēia mau mea ua hanaʻole mai kekahi o Hama Radio ua aneane ua hoʻohiki. Akā, kā lākou e pili ana e e akahele - ia Aloha nā mīkini home, a hana ana me ke anakahi uila, a ina ia mea liʻiliʻi, akā, i ka hopena, e ia ma ka liʻiliʻi loa kaʻawaʻawa loa ignoring maluhia rula.
