Kacher Brovina - he aha te mea reira me aha tona tono mahi he? Kia pehea te mahi Kacher Brovina?

Kacher Brovina Ko te whāinga taketake o te oscillations hiko. Ka taea te huihui te reira i runga i ngā āhuatanga reo irirangi hohe. I te kau, ka te whakaminenga, ko te mara whakamahia ranei transistors pourua, i te iti rawa - korere irirangi (triodes me pentodes). Kacher Brovina whakaaro i roto i 1987 e te kaipūkaha irirangi Soviet Vladimirom Ilichom Brovinym rite huānga kāpehu hiko. Kia titiro a i roto i atu taipitopito he aha te ahua o te pūrere.

Ko te taea unknown o ngā huānga Semiconductor

Kacher Brovina - tenei ahua o te generator, huihui i roto i tetahi transistor me whakahaere, kia rite ki te ihi, tikanga pouri. E whakaatu ana te pūrere nga āhuatanga ngaro, e rā hoki ki te rangahau Nikoly Tesla. e kore e ratou pai ki tetahi o te ariā hou o te autōhiko. Te āhua, Kacher Brovina ko te ahua o te Semiconductor arrester, i roto i nei rere te rere o nāianei hiko i roto i te karaihe e hāngai ana transistor-, bypassing te taahiraa o hanga he pewa hiko (wē). Ko te mea tino ngā i roto i te mahi o te pūrere - ko e i muri i te tino faaho'ihia mai te rärangi o te maramara transistor. Ko tenei e tika ana ki te meka i te wae pūtake o te mahi e whakamahia ana te raru horonga reversible, i roto i te rerekē ki te wera, kia nei ko tina heke te Semiconductor. Heoi, ka rite ki taunakitanga o te aratau o mahi o te transistor arahi tauākī autaki anake. e kore te Tangata, ki te kahore te ihi o te mahi transistor i roto i te pūrere whakaahuatia uiui i roto i te taipitopito. Na ko te tika i te whakaaro o Brovina tenei. Hei tauira, ki te whakaū i he hakari "kachernogo" aratau pūrere ihi te meka e whai ake nei: mea ratou, kahore mea aha ki te wehenga tawhiti o te taputapu hono he wehenga tawhiti tīkorikori, pini, whakaatu ana ki a ratou kia pai tonu.

Pea Kacher - he ahua o te ārai oscillator?

He he he putanga taua. I muri i te taiawhio hiko o te pūrere ko kaha haamana'oraa o te generator o ponana hiko. Heoi, fakamamafa'i te ihi e te vai tona pūrere pērā kaupapa whakaarohia unobvious. E horo'a te reira i te whakamārama o ngā tukanga tinana roto te transistor kē. I roto i te Semiconductor oscillator ārai wā whakatuwheratia rite ki te hua o te rere o nāianei i roto i te ara iahiko urupare turanga pōkai. Ko te transistor Kacher pera-ka karanga tikanga kore-mahino ki kia tutakina tūturu (ie. Ko tonu e taea ki te uru i te reira K. Creation Ākinga Pūngao i roto i te mekameka hono ki te urupare pōkai turanga Semiconductor). A, no te hanga e tenei nāianei e te haaputuputuraa o utu hiko i roto i te rohe turanga ki te ruke atu i runga i nui rawa i te ngaohiko paepae hanga wehenga horonga. Heoi, nga transistors whakamahia kore Brovin hangaia ki te mahi i roto i te aratau horonga. Hoki tenei raupapa hangaia Semiconductors motuhake. E ai ki te ma'imi, taea te whakamahi transistors pourua kore anake, engari te mara, me te he ngongo irirangi, ahakoa te meka e he mahi ahupūngao faufaa rerekē ratou. ai tenei te aronga e kore i runga i te rangahau o te transistor i Kačerov, a i roto i ngā te mahi aratau pini o te ara iahiko katoa. I roto i te meka, enei akoranga me whai wāhi i roto i Nikola Tesla.

Ko te ihi o te mea

I te tau 1987 whai wāhi Brovin i te hoahoa o te kāpehu, e taea ai te kaiwhakamahi ki te tautuhi i te wahi o te marama e kore e roto i te tirohanga, engari ki te awhina o rongo. Kei te whakaritea te reira ki te whakamahi i tētahi generator auau audio, te huri i te reo i roto i runga i te wāhi o te whanaunga pūrere ki te papa autō o te ao. Ka rite ki te turanga whakamahia ārai oscillator, te whakapai ake i te reira, me te pūrere hua i muri i huaina Kacher Brovina. ara iahiko generator pono ko te pai: kua hanga ki runga ki te parau tumu puāwaitanga, anake te koropiko urupare tāpiri e hāngai ana i runga i te hiko o te matua e hāngai ana i runga i te rino amorphous. Whakakē te reira i te uruhanga mō uara ngaohiko iti (hei tauira, te papa autō o te ao). rongo kāpehu Sound te ka taui te takotoranga rite te tikanga.

pānga taha

Analysis o nga āhuatanga o te ara iahiko huihui whakakitea ētahi ōritetanga i roto i tona mahi ki ngā ariā tikanga. I kitea te reira e riro i te tohu i runga i te electrodes o te transistor whanganga e amo te tīkorikori āhua pai, me te kino o te puna ngaohiko, i nga wa katoa te taua wehenga tawhiti. Na, o npn transistor hoatu he tohu pai i runga i te kaikohi me PnP - tōraro. Tenei ko tenei pānga me ngā Kacher Brovina. Ko te pūrere ara iahiko Kei roto he hiko i roto i te mahi o te pūrere he ātete tata ki te kore. tonu te generator ki te rere noa, no te tata i te aukume tūturu kaha ki te matua. saturates matua autō, hua i roto i te tukanga ārai ki te mutu e tika ana ki te mutunga o te huringa i roto i te circuitry urupare koropiko. I roto i tenei take, e kore e te matua e tu i roto i hysteresis, e kore i taea e kitea ai e te tau Lissajous. Ko te kaha tīwera o te ngātere i te kaikohi o te transistor ko e rima nga wa ki runga ake i te ngaohiko mana supply.

Kacher Brovina: tono mahi

I te kau whakamahia te pūrere e rite te discharger wē ki te whakaputa ngātere o nāianei hiko i waho arcing i roto i nga whakaaro tauira. Ko te one tino whakamahia nuitia - Kacher Brovina me Tesla hiko. Tenei Ko te mea te pewa e puta ana i roto i te arrester, i roto i te parau tumu, ko te aunui generator oscillation hiko. Ko reira anake te mea mo te hanganga o ngātere nui-auau, e wātea ana Nikola Tesla. I tua atu, kua hanga te ma'imi e hāngai ana ngā pūrere ruri Katscher, e tukua ana ki te whakatau i te uara pū i waenganui i te generator me te pūoko radiation.

Scientists ueue i

Ko te whakaahuatanga i runga o te pūrere, me tona parau tumu mahi (e taea te kite ngā) fehangahangai pūtaiao tuku iho. Ko te totohe whakaaturanga raraunga ihi kitea, ui ia tonutia ana katoa tahi ki te mahi ki nga inenga ihoa o ngā tawhā o tona pūrere. Heoi, e kore kua te tūranga o te maia i roto i tenei mea ano arahina ki tetahi hua, e kore e taea e kaimātai pūtaiao whakamārama i te tukanga-tinana i roto i te Semiconductor.

He nui tenei

Ka pea hei whakaahuatanga pānga Katscher Brovina i te wāhi e tata ana ara ki te tahuri Āmio o te ngota e karapoti matū. tohua ana tēnei e te ihi i roto i ngā ki te hanganga o te pūrere i roto i te oko karaihe hiri, i nei whakatahia rangi te ki te whakaiti i te taumata pēhanga reira. Ka rite ki te hua, e kore wheako pānga overunity e pai tukua te taputapu ki te whakarōpū i rite te mīhini nekehanga mau tonu, e kore (me te haunga o ngā tūturu i te mana tuku i roto i te waea). Tenei i faaite tuatahi Nikola Tesla. Heoi, ko te taea pānuitanga teka o ine mea mana kaute whakamārama pākau i, kaua āhua kotiro o te rere o nāianei i roto i te mekameka pūngao Kačerov. Ahakoa kei te hangaia ine pūrere momo hei whakamatau mo rānei pūmau, sinusoidal ranei (hawarite) nāianei.

Me pēhea te ki te huihui o ratou ringa ake Kacher Brovina

Ki te, i muri i te tai'oraa i te tuhinga, he hiahia koe i roto i tenei pūrere, ka taea e hanga e koe i te reira koe. Ko na ohie e taea te hanga te reira ara he hobbyist tauhou te pūrere. Kacher Brovina (kaupapa i homai i raro) kai te Nic whakarerekētia 12 V, 2 A, pau 20 Watts. faafariu te reira i te tohu hiko i roto i te auau o te 1 MHz ki te tōtika o 90%. Hoki whakaminenga, Me matou putorino kirihou 80h200 mm. ka maru ia te reira i te kopiko tuatahi, me te tuarua o te resonator. Kei te wahi hiko katoa o te pūrere e i roto i te waenganui o te okana. Ko te tino pūmau tenei kaupapa, ka taea e rere i te reira no te rau o haora, kahore te mea kiano i matao. Kacher Brovina ki samozapitkoy he ngā no te mea te reira e taea ki te marama i te haukura kahore e rama hono ki te tawhiti o 70 cm. Ko te pūrere faahiahia whakaatu mo te kura taiwhanga wānanga ranei, me te he pūrere papamahi mō te whakangahau manuhiri mō te hono ui tinihanga ranei.

circuitry whakaminenga Whakaahuatanga

Ko te ma'imi taunaki ana te whakamahi o te KT902A transistor pourua KT805AM ranei (ahakoa, ka taea e koe te kohikohi Kacher Brovina FET). Me noaa te huānga Semiconductor ki te whakamahana kaha i muri i pani te whakapiri thermally conductive. Ka taea hoki te tāuta e koe te mātao. Parenga whakaaetia ki te whakamahi i taimau, me te C1 pūnga ki tutakina. Tuatahi, kia te tuatahi awhiowhio kia maru ia i te i te waea 1 mm (4 hohoko), na te awhiowhio te waea tuarua e kore atu i 0.3 mm. Te tahuri kikī awhiowhio te maru ia i te ki te tahuri. Hoki tenei whakaaro, tāpiri reira ki te mutunga runga o te ngongo, me te timata ki te hau, promazyvaya conductive piripiri PVA katoa 20 mm. Kati ki te hanga 800 hohoko. Fakamau mutunga me te tūhoto tukunga pēne kiriweti. kia te kopiko kia maru ia i roto i te ahunga taua, he mea nui kia kore ratou e pa ki. I tua atu ko reira e tika ana ki te tūhoto te tihi o te ngongo tuitui ngira me soldered tukunga awhiowhio te mutunga. tūhoto Next taiawhio hiko, me te tuu i te reira tahi ki te whakamahana i roto i te ngongo kirihou. Tenei ko te wae timatanga te Kacher Brovina.

Me pēhea te ki te hanga 'pūkaha katote'?

Tīmata i te pūrere huihui ki te ahotea iti rawa - 4 volts, na reira āta timata ki te whakapiki ake i, i te kore wareware ki te aroturuki nāianei. Ki te mea kua kohia e koe te kaupapa i runga i te KT902A transistor, ki te puku rīpene i te mutunga o te ngira puta i 4 volts. Ki te whakanui ake i ngaohiko ka nui ake i te reira. Ki runga ki te taenga 16 volts tahuri te reira ki te "Red." I 18 hua ki āhua 17 mm, me i 20 V hauruke hiko ka rite mahi pūkaha katote tūturu.

mutunga

Ka rite ki a koutou e taea te kite, he timatanga te pūrere me e kore e rapua e fakamolé nui. Ka taea e te kohikohi te reira ki tou tamaiti, no te mea e aroha ana tamariki ki te tākaro ki te "repe". Na ko te painga rua konei: e kore anake e e waiho te tamaiti i roto i te mahi, i te reira puta hoki te māia-whaiaro. Ka taea ki te whai wāhi i roto i te kura ataahua ki tona hanganga whakamanamana ranei ki o koutou hoa ia. Ko wai e matau ana, pea whakawhetai ki te whakaminenga o te taua takawairore māmā whakawhanake ia he moni i roto i te hikohiko irirangi, me i roto i te heke mai i ka hei tō tamaiti te kaituhi o tetahi o te tenenga.
