Chiyambi cha mikhalidwe ya ma diode

Kutchulidwa

mwachidule

Diode ndi chida chokhala ndi maelekitirodi awiri, mphambano ya PN yopangidwa ndi semiconductor wa P-mtundu ndi semiconductor wa mtundu wa N. Pakadali pano imangoyenda kuchokera ku anode wa diode ndikutuluka kunja kwa cathode. Ili ndi gawo lamagetsi lokhalokha ndipo limagwiritsidwa ntchito mozungulira ma circifier.

Makhalidwe abwino

Mukuzungulira, cathode ya diode imalumikizidwa kumapeto otsika kwamagetsi, ndipo anode imalumikizidwa kumapeto kwamphamvu zamagetsi.Panthawi ino, diode idzatsegulidwa.Mtunduwu umatchedwa kukondera kutsogolo. Pamene kusiyana kwamagetsi pakati pa malekezero awiri a diode ndikochepa kwambiri, diode silingathe kuyatsidwa. Chifukwa zamakono kudzera pa diode ndizochepa kwambiri. Pokhapokha voliyumu yakutsogolo ikafika pamtengo winawake (voliyumu yotsika kwambiri ya silicon diode ndi 0.6V, voliyumu yotsika kwambiri ya germanium diode ndi 0.2V) pomwe diode idzatsegulidwenso. Pambuyo poyatsa, ma voliyumu opingasa pa diode amakhalabe osasinthika (pafupifupi 0.7V yama diode a silicon komanso pafupifupi 0.3V yama germanium diode) Izi zimatchedwa kuti diode forward voltage.

Makhalidwe obwereza

Mukuzungulira, pomwe code ya diode imagwirizanitsidwa ndi kutha kwamphamvu kwamphamvu, ndipo anode amalumikizidwa kumapeto otsika a voliyumu, diode ili m'malo odulidwa panthawiyi ndipo palibe mayendedwe apano. Pamene diode ikubwerera m'mbuyo, ngati pakadali pano pali mphamvu yofooka yomwe ikudutsa mu diode, uwu ndiye mkhalidwe wotayikira. Mphamvu yamagetsi yotsatizana modutsa wamba ikafika pamtengo winawake, mphamvu zakumbuyo zidzawonjezeka kwambiri.
