1.Kusankhidwa kwa thyristor mu mndandanda ndi dera lofanana la resonant
Pamene thyristors amagwiritsidwa ntchito mndandanda ndi ofanana resonant dera, chipata choyambitsa kugunda ayenera kukhala wamphamvu, panopa ndi voteji ayenera kukhala bwino, ndi conduction ndi kuchira makhalidwe a zipangizo ayenera kusankhidwa ndi ntchito yomweyo.Makamaka ngati zipangizozi zikugwira ntchito ndi di/dt yapamwamba ya inverter circuit motsatizana, mawonekedwe obwezeretsa m'mbuyo amakhala ndi gawo lalikulu pakulinganiza mphamvu yamagetsi.
2.Kusonkhanitsa kutentha kwa kutentha ndi chipangizo
Kuzizirira kwa misonkhano kumaphatikizapo kuziziritsa kwachilengedwe ndi sink ya kutentha, kuziziritsa mpweya mokakamiza komanso kuziziritsa madzi.Kuti chipangizochi chigwiritse ntchito modalirika pakugwiritsa ntchito, ndikofunikira kusankha choyeneramadzi ozizira heatsinkndi kusonkhanitsa ndi chipangizo bwino.Izi zimatsimikizira kukana kwamafuta a Rj-hs pakati pa sinki ya kutentha ndi thyristor/diode chip kumakwaniritsa zofunika kuzizira.Miyezo iyenera kuganiziridwa motere:
2.1 Malo okhudzana ndi kutentha kwa kutentha ayenera kufanana ndi kukula kwa chipangizo kuti asawonongeke kapena kuwonongeka kokhotakhota kwa chipangizocho.
2.2Kusalala ndi kuyeretsedwa kwa malo olumikizirana ndi kutentha kuyenera kumalizidwa kwambiri.Ndikoyenera kuti roughness ya pamwamba pa sinki ya kutentha ikhale yocheperapo kapena yofanana ndi 1.6μm, ndipo kutsetsereka kumakhala kochepa kapena kofanana ndi 30μm.Pamsonkhano, malo olumikizirana ndi chipangizocho ndi choyakira chotenthetsera chizikhala choyera komanso chopanda mafuta kapena zinyalala zina.
2.3 Onetsetsani kuti malo olumikizirana ndi chipangizocho ndi choyatsira kutentha ndizofanana komanso zokhazikika.Pamsonkhano, m'pofunika kugwiritsa ntchito kukakamiza kupyolera pakati pa chigawocho kuti mphamvu yosindikizira igawidwe mofanana pa malo onse okhudzana.Posonkhanitsa pamanja, tikulimbikitsidwa kugwiritsa ntchito wrench ya torque kuti mugwiritse ntchito ngakhale mphamvu ku mtedza onse omangirira motsatana, ndipo kukakamiza kuyenera kukwaniritsa zomwe zikuyenera.
2.4Chonde samalani kwambiri kuti muwonetsetse kuti malo olumikiziranawo ndi oyera komanso athyathyathya ngati mubwerezanso kugwiritsa ntchito sinki yoziziritsira kutentha kwamadzi.Onetsetsani kuti palibe sikelo kapena kutsekeka m'bokosi lamadzi, ndipo makamaka osagwedezeka pamalo olumikizana.
2.5 Chojambula chojambula cha sinki yoziziritsira madzi
Chinthu chofunika kwambiri kuti muwonetsetse kuti ntchito yodalirika ya dera ndiyo kusankha chipangizo choyenerera komanso chozama cha kutentha.Themkulu mphamvu kapisozi thyristorndi diode yopangidwa ndi Runau Semiconductor imawunikira kwambiri pamagwiritsidwe pafupipafupi.Magetsi omwe ali nawo amachokera ku 400V mpaka 8500V ndipo amachokera ku 100A mpaka 8KA.Ndibwino kwambiri mu mphamvu yachipata choyambitsa pulse, kulinganiza bwino kwa machitidwe ndi kuchira.Madzi ozizira otentha otentha amapangidwa ndikupangidwa ndi zida za CAD ndi CNC.Ndizothandiza kupititsa patsogolo magwiridwe antchito a zida.
