Mfundo yogwirira ntchito komanso ntchito yayikulu ya thyristor

1. Mfundo yogwirira ntchito ya khalidal ndi:

1. Kupanga thyristor kuyatsa, imodzi ndikugwiritsa ntchito mphamvu yamagetsi pakati pa anode A ndi cathode K, ndipo inayo ndikulowetsa magetsi oyambira pakati pamagetsi ake a G ndi cathode K. Pambuyo poyimitsa thyristor, kumasula batani lophimba, kuchotsa choyambitsa voteji, ndi kukhalabe pa boma.

2. Komabe, ngati mphamvu yamagetsi yosinthika imagwiritsidwa ntchito pa anode kapena ma elekitirodi olamulira, thyristor siyingathe kuyatsidwa. Ntchito yolamulira ndikutsegula thyristor pogwiritsa ntchito poyambira, koma siyingazimitsidwe. Kuzimitsa thyristor woyendetsa kumatha kudula magetsi a anode (sinthani S mu Chithunzi 3) kapena kupangitsa kuti anode ikhale yocheperako mtengo wocheperako pochita conduction (yotchedwa yotsogola). Ngati magetsi a AC kapena magetsi a DC akugwiritsidwa ntchito pakati pa anode ndi cathode ya thyristor, thyristor idzazimitsa yokha magetsi akamadutsa zero.

2. Ntchito za thyristor mdera ndi izi:

1. Wosintha / wokonzanso.

2. Sinthani kupanikizika.

3. Kutembenuka kwafupipafupi.

4. Sinthani.

Imodzi mwa ntchito zofunika kwambiri za SCR ndikukhazikika pakadali pano. Thyristors amagwiritsidwa ntchito kwambiri pakuwongolera zokha, zamagetsi zamagetsi, zamagetsi zamagetsi ndi zida zapanyumba. Thyristor ndi chinthu chosinthira. Nthawi zambiri imasungidwa m’malo osadutsa mpaka itayambitsidwa ndi siginecha yocheperako kapena “kuyatsidwa” kuti idutse. Ikayatsidwa, imatsalira ngakhale chizindikirocho chitachotsedwa. M’njira, kuti idulidwe, mphamvu yamagetsi ingagwiritsidwe ntchito pakati pa anode ndi cathode kapena zomwe zikuyenda kudzera mu diode ya thyristor zitha kuchepetsedwa kukhala pansi pamtengo wina.
