Kodi pali kusiyana kotani pakati pa kugwiritsa ntchito ma triacs ndi unidirectional anthony?

Ma SCR adagawika unidirectional ndi bidirectional, ndipo zizindikirazo ndizosiyana. Unidirectional SCR ali ndi mphambano zitatu za PN, ndipo maelekitirodi awiri amatengedwa kuchokera kunja kwa P pole ndi N pole, komwe kumatchedwa anode ndi cathode, motsatana. Mzati wa P umatsogolera ku mtengo wowongolera.

Njira imodzi SCR imakhala ndi mawonekedwe ake apadera: pomwe anode imagwirizanitsidwa kuti isinthe mphamvu yamagetsi, kapena pamene anode yolumikizidwa kuti ipititse patsogolo ma voliyumu koma ma elekitirodi olamulira samagwiritsidwa ntchito pamagetsi, sachita, ndipo pamene anode ndi ma elekitirodi olumikizirana agwirizana kutumiza magetsi nthawi yomweyo, Idzakhala dziko loyendetsa. Ikatsegulidwa, magetsi oyendetsa amasiya kuwongolera. Mosasamala kanthu kuti pali magetsi oyendetsa kapena polarity of the control voltage, nthawi zonse imakhala ikuyenda. Ngati mukufuna kuzimitsa, Kungochepetsa ma anode voltage pamtengo wotsutsa kapena kusintha.

Zipini zambiri za triac zimakonzedwa kuyambira kumanzere kupita kumanja motsatira T1, T2, ndi G (pomwe pini yama elekitirodi ili pansi, moyang’ana mbali ndi zilembo). Kukula kwa choyambitsa kugunda kuwonjezeredwa kwa ma elekitirodi olamulira G kapena Nthawi ikasintha, imatha kusintha kukula kwakapangidwe kake.

Kusiyanitsa ndi unristirectional thyristor ndikuti pamene polarity of the pulse pulse on the bidirectional thyristor G isintha, mayendedwe ake owongolera amasintha ndikusintha kwa polarity, kuti katundu wa AC athe kuwongoleredwa. Pambuyo poyambitsidwa, silicon imangoyenda mbali imodzi kuchokera ku anode kupita ku cathode, chifukwa chake thyristor imatha kukhala yopanda tanthauzo komanso yolowera mbali ziwiri.

Thyristors amagwiritsidwa ntchito kwambiri popanga zamagetsi, monga MCR-100 njira imodzi ndi TLC336 ya njira ziwiri.
