Kodi SMD inductor imagwira ntchito yanji mu nyali zopulumutsa mphamvu za LED?

Popeza ma chip inductors amatha kukulitsa moyo wautumiki wazinthu zambiri zamagetsi ogula, kupititsa patsogolo mtundu wazinthu, kusakhala bwino, ndi magwiridwe antchito, agwiritsidwa ntchito ndi opanga ambiri.

Sizikugwiritsidwa ntchito pazida zamagetsi zokha, komanso zida zomvera, zida zomaliza, zida zam'nyumba ndi zinthu zina zamagetsi ndi zamagetsi, kuti maginito amagetsi asasokonezedwe, komanso nthawi yomweyo, samasokoneza ma sign kapena ma radiation a electromagnetic opangidwa ndi zida zina zozungulira. .

Nyali zopulumutsa mphamvu zimagwiritsidwa ntchito kwambiri pamoyo wathu; ndipo nyali zopulumutsa mphamvu za LED zimapangidwa makamaka ndi ma semiconductor kuwala-emitting diode; iwo ndi mtundu wa kuwala komwe kumadya mphamvu zochepa ndipo kumakhala ndi moyo wautali wautumiki.

Dera lamkati la nyali yopulumutsa mphamvu ya LED ndi gawo lapansi lamagetsi, lomwe limaphatikizapo ma electrolytic capacitors, resistors, inductors, ceramic capacitors, etc. .

makamaka kutsekereza AC ndi DC, ndikuletsa ma frequency apamwamba komanso otsika pafupipafupi (sefa). Zachidziwikire, dera lamagetsi limatchinga AC ndi DC. Zitha kuwoneka kuti kukana kwa chip power inductor ku DC kuli pafupifupi ziro.

Pansi pa zomwe zikuchitika kuti dera limalola kudutsa, chip inductance imalepheretsa kupita kwa AC point, imateteza bolodi kuti isawonongeke, ndikuwonjezera kwambiri moyo wautumiki wa LED.
