Mtsogoleri Current ndi manja anu: chiwembu ndi malangizo. DC yang'anira

Masiku ano, zipangizo ambiri amapangidwa ndi malamulo panopa. Choncho wosuta amatha kulamulira chipangizo mphamvu. zipangizozi amatha kugwira ntchito Intaneti ndi variable ndi zonse panopa. Ndi mamangidwe a owongolera zosiyana. Mbali yaikulu ya chipangizo angatchedwe thyristors.

Komanso yofunika amazilamulira zinthu ndi resistors ndi capacitors. amplifiers maginito pokhapokha ntchito zipangizo mkulu voteji. Kusalala kusintha zida operekedwa ndi modulator lapansi. Nthawi zambiri zikhoza kupezeka chabe kutembenukira zosintha awo. Komanso, dongosolo ali Zosefera kuti kuthandiza kusalaza phokoso mu dera la. Chifukwa ichi, linanena bungwe panopa ndi wolimba kuposa polowera lapansi.

Chiwembu yosavuta Mtsogoleri

Galimoto panopa Mtsogoleri ochiritsira thyristors adzatenge ntchito diode. Masiku ano, yodziwika ndi kukhazikika mkulu ndi ukhoza kwa zaka zambiri. Nawonso triode analogues akhoza kudzitama za dzuwa Komabe, lingathe ali wamng'ono. Pakuti chabwino panopa transistors madutsidwe mtundu munda zotsatira ntchito. Dress zosiyanasiyana za dongosolo angagwiritsidwe ntchito.

Pofuna kuti yang'anira panopa kwa 15V, mukhoza bwinobwino kusankha chitsanzo ndi KU202 ankachita. Chakudya n'zosiyana voteji kumachitika chifukwa capacitors, zimene pa chiyambi cha unyolo. Modulators mu owongolera kawirikawiri ntchito makina osindikizira. Ndi mamangidwe, iwo ndi wosavuta ndipo amalola kusintha yosalala kwambiri mlingo pano. Kuti ziziyenda bwino mu voteji kumapeto kwa unyolo Zosefera apadera ntchito. Mkulu-analogues angathe kuikidwa okha kusintha zoposa 50 V. ndi kuwasokoneza mu atomu iwo akulimbana bwino, ndi katundu chachikulu thyristors ndi musataye.

DC chipangizo

The yang'anira dera DC ali madutsidwe mkulu. Pankhaniyi zomvetsa matenthedwe mu chipangizo ndi kochepa. Kuti yang'anira DC, thyristor diode mtundu chofunika. Apa mu nkhani iyi idzakhala mkulu chifukwa mofulumira ndondomeko voteji kutembenuka. The resistors mu dera la ayenera kutha kupirira kukana pazipita 8 ohms. Pankhaniyi, izo zidzapangitsa kuti kutentha imfa yochepa. Pomaliza pake, modulator mwamsanga overheat.

analogues Modern cholinga kuzungulira kuchepetsa kutentha kwa madigiri 40, ndipo zimenezi ziyenera n'komwe. Field zotsatira transistors angathe kudutsa ziliri pa dera mu njira imodzi yokha. Poganizira zimenezi, izo aikidwa pa chipangizo iwo ayenera kuti thyristor lapansi. Chifukwa, mlingo wa kukana zoipa ndi osapitirira 8 ohms. Mkulu-pafupipafupi fyuluta pa DC Mtsogoleri anaika yosowa kwambiri.

Model AC

AC yang'anira amakhala mu thyristors izo ntchito kokhako triode. Nawonso transistors ntchito mtundu muyezo munda. The capacitors mu dera ntchito okha olimba. Kukakomana ndi Zosefera mkulu-chikudutsa mu zipangizo za mtundu uwu ndi zotheka, koma kawirikawiri. Mavuto ndi kutentha mu zitsanzo ndi kuthetsedwa likuvutika zimachitika Converter. Iwo anaika mu dongosolo la modulator lapansi. Zosefera Low-chiphaso ntchito owongolera ndi mphamvu 5 V. Management wa cathode mu zida za ikuchitika ndi kupondereza athandizira voteji.

DC olimba maukonde amapezeka bwino. Pofuna kuthana ndi katundu mkulu, ntchito n'zosiyana zener zina. Iwo transistors zikugwirizana ntchito fulumizitsa. Pankhaniyi, Mtsogoleri panopa ayenera kupatsana komabe munthu pazipita nagruzkui 7 A. The mlingo Kuchepetsa kukana mu dongosolo sayenera upambana 9 ohms. Pankhaniyi, ife angayembekezere kutembenuka mwamsanga.

Bwanji Mng'oma wa Mtsogoleri kwa soldering chitsulo?

Kupanga yang'anira panopa ndi manja awo kwa soldering n'kotheka, ntchito thyristor triode mtundu. Komanso amafuna transistors ochititsa kuti ndi otsika chikudutsa fyuluta. Capacitors mu zida za ntchito mu kuchuluka kwa osapitirira mayunitsi awiri. anode panopa kuchepa Pankhaniyi ziyenera kuchitika msanga. Pofuna kuthetsa ndi polarity zoipa, anapereka zimachitika converters.

Iwo ali abwino kwa voteji sinusoidal. Mwachindunji kulamulira panopa chingapezeke popotoloka mtundu Mtsogoleri. Komabe, analogs Kankhani-batani anapezeka ku nthawi yathu. Kuteteza chipangizo, thupi amagwiritsa kutentha zosagwira. converters Resonant mu zitsanzo akhoza kupezeka. iwo ali osiyana poyerekeza ndi Anzawo ochiritsira, cheapness ake. Mu msika awo nthawi zambiri amapezeka ndi zizindikiro RR200. The madutsidwe wa panopa Pankhaniyi adzakhala otsika, koma ulamuliro elekitirodi ndi ntchito tikulimbana.

Zipangizo naupereka kwa

Kuti yang'anira zatsopano naupereka batire, thyristors pokhapokha chofunika mtundu triode. Lanu limagwirira mu nkhani iyi ndi kulamulira ulamuliro elekitirodi a dera la. zipangizo FET ntchito nthawi zambiri. Zolemba malire katundu iwo 9 A. Low-pafupipafupi Zosefera kwa owongolera amenewa sizikugwirizana unambiguously. Ichi ndi chifukwa chakuti matalikidwe a phokoso mu atomu si mkulu. The njira yosavuta, ntchito Zosefera resonant. Mu nkhani iyi, madutsidwe, iwo sititi chizindikiro. Kutentha kutayika opha ayenera kukhala negligible.

Ntchito opha Triac

Triac owongolera zambiri ntchito zipangizo mphamvu si upambana 15 V. Pankhaniyi, iwo amatha kupirira voteji malire 14 A. Ngati ife kulankhula za zipangizo kuunikira, iwo sangathe ntchito zonse. iwonso sali oyenera tiransifoma mkulu-voteji. Komabe, wosiyana kwa iwo mawailesi angathe zikugwira ntchito stably ndipo popanda vuto lirilonse.

Owongolera kwa katundu resistive

Galimoto Mtsogoleri zatsopano katundu yogwira amafuna kugwiritsa ntchito triode thyristor mtundu. Mbendera amatha kudali malangizo onse. Yafupika anode panopa akupezeka dera ndi kuchepetsa chipangizo pafupipafupi Kuchepetsa. Pafupifupi chizindikiro ichi fluctuates mozungulira 5 Hz. Zolemba malire voteji pa linanena bungwe akhale pa 5 V. Chifukwa chaichi, ndi resistors chagwiritsidwa mtundu kumunda kokha. Komanso, ntchito ya capacitors ochiritsira, omwe pafupifupi amatha kupirira kulimbikira 9 ohms.

Kugunda zener kusintha zimenezi si zachilendo. Ichi ndi chifukwa chakuti matalikidwe ya mafunde mu atomu ndi lalikulu kwambiri ndipo muyenera kuthana nazo. Apo ayi, kuwonjezeka transistor kutentha mwamsanga ndipo iwo adzakhala opanda phindu. Pofuna kuthetsa ndi akuponya zimachitika transmitters ntchito zosiyanasiyana. Pankhaniyi akatswiri masiwichi Angagwiritsidwenso ntchito. Iwo anaika mu opha wa FETs lapansi. Pa nthawi yomweyo iwo amakhudzana ndi capacitors sayenera.

Kodi kupanga chitsanzo cha ulamuliro gawo?

Kupanga gawo panopa Mtsogoleri ndi manja anu, mungathe kugwiritsa ntchito thyristor KU202 ankachita. Pankhaniyi, mwa kundipatsako kwa n'zosiyana voteji ndidzadutsa yoletsedwa. Komanso chisamaliro ayenera kumwedwa kuchepetsa pamaso pa capacitor impedance kuposa 8 ohms. Amalipiritsa kwa Pankhaniyi angathe kumwedwa PP12. Chipata elekitirodi Pankhaniyi kupereka madutsidwe wabwino. Kusintha Converters mu opha wa mtundu uwu n'zochepa. Ichi ndi chifukwa chakuti pafupifupi pafupipafupi mlingo mu dongosolo choposa 4 Hz.

Chifukwa cha zimenezi, thyristor ndi amphamvu nkhawa, amene amakwiya ponso kulimbikira negative. Kuti athetse vutoli, anthu ena amanena ntchito Kankhani-Chikoka converters. ntchito yawo inamangidwa pa voteji kukalowa. Anapanga popanda mtundu wa yang'anira panopa ndi mayiyu azivutika pakhomopo. Monga ulamuliro, zonse zimadalira kufunika kufufuza chopatsilira.

Zida zimachitika Mtsogoleri

Kuti kusintha yang'anira panopa, thyristor triode mtundu chofunika. Ulamuliro voteji imagwiridwa ndi liwiro lalikulu. Mavuto ndi n'zosiyana chipangizo kuchititsa ali zimatheka ndi mtundu ochititsa kuti transistor. Capacitors anaika mu dongosolo okha awiri unsembe. Kuchepetsa anode ziliri pa dera la kumachitika kusintha udindo wa thyristor lapansi.

Limagwirira lanu mu opha wa mtundu uwu wayikidwa akhale resistors lapansi. Kuti ziziyenda bwino mu Zosefera malire pafupipafupi angagwiritsidwe ntchito zosiyanasiyana. Zitatero, ndi kukana sizabwino yang'anira sayenera upambana 9 ohms. Pankhaniyi, izo kupirira lalikulu katundu panopa.

Chitsanzo ndi kuyamba yosalala

Pofuna kupanga thyristor mphamvu Mtsogoleri ndi kuyamba zofewa, muyenera kusamalira modulator lapansi. Wotchuka kwambiri imatengedwa kuti kutembenukira Akhristu lero. Komabe, aliyense ali osiyana kwambiri. Pankhaniyi, zimadalira pa bolodi, amene ntchito chipangizo.

Ngati ife kulankhula za kusinthidwa wa mndandanda wa CG, iwo ntchito pa opha yosavuta. Kwambiri wangwiro, iwo alibe aime ndi ena glitches akadali. Apo ayi, zinthu ndi owongolera kwa tiransifoma. Kumeneko, monga ulamuliro, zosintha digito chagwiritsidwa. Chifukwa, mlingo wa kukhota mbendera ali kwambiri yafupika.
