Udindo wa ma capacitor pakupereka magetsi

Ma capacitor angagwiritsidwe ntchito posintha magetsi kuti achepetse phokoso la ripple, kukonza kukhazikika kwa magetsi komanso kuyankha kwakanthawi, koma pali mitundu yambiri ya iwo, tiyeni tiwone pamodzi.

Mtundu wa capacitor

Ma capacitor amatha kugawidwa m'ma chip capacitors ndi ma plug-in capacitors malinga ndi phukusi, ma ceramic capacitors, ma electrolytic capacitors, ma mica capacitors, ndi zina zotero malinga ndi medium, ndi fixed capacitors, semi-fixed capacitors, ndi variable capacitors malinga ndi kapangidwe kake. Mu switching power supply, timagwiritsa ntchito kwambiri ma ceramic capacitors, electrolytic capacitors ndi tantalum capacitors.

Magawo ofunikira a capacitor

Kumvetsetsa magawo a key a capacitor kumatha kusankha mtundu wake mwachangu ndikuugwiritsa ntchito moyenera. Magawo ofunikira a ma capacitor onse ndi ofanana, kuphatikiza mtengo wa capacitance wa capacitor, mtengo wa voltage yopirira ya capacitor, ESR ya capacitor, kulondola kwa mtengo wa capacitor, ndi kutentha kovomerezeka kwa capacitor.

Makhalidwe a capacitor yokha

Ma capacitor a Ceramic ali ndi capacitance yaying'ono, makhalidwe abwino a high-frequency, kutentha kwakukulu kogwirira ntchito, ESR yaying'ono komanso voliyumu yaying'ono kuposa ma capacitor a electrolytic;

Capacitance ya electrolytic capacitor ikhoza kukulitsidwa, koma kutentha kwa ntchito ndi kochepa, ESR ndi yayikulu, ndipo pali polarity;

Ma capacitor a Tantalum ali ndi ESR yaying'ono kwambiri, ndipo mphamvu yawo ndi yayikulu kuposa ma capacitor a ceramic. Ali ndi polarity, chitetezo chochepa, ndipo ndi osavuta kugwira moto.

Mvetsetsani makhalidwe a mitundu itatu ya ma capacitor omwe ali pamwambapa, ndipo mutha kuwagwiritsa ntchito mosavuta.

Chilengedwe

Malo amkati mwa derali akuphatikizapo ma frequency, voltage value, current value, ntchito yayikulu ya capacitor mu derali, ndi zina zotero; mtundu wa capacitor ukhoza kudziwika malinga ndi ma circuit frequency; voltage value ya capacitor yosankhidwa ikhoza kudziwika malinga ndi voltage value; ntchito yayikulu mu derali ingagwiritsidwe ntchito Onani mtengo wa capacitance wa capacitor yosankhidwa; malo akunja ogwiritsira ntchito derali, kuphatikiza kutentha kwa chinthu chomwe chikugwira ntchito, ndi zofunikira zachitetezo, zingagwiritsidwe ntchito ngati chisonyezero chosankha capacitor.
