Magungano kubatana kwakaita capacitors somushonga kusarudzwa capacitance

Condenser - nevakawanda redhiyo zvinoriumba, izvo zvinowanikwa zvose pfungwa. Inoitwa conductors vaviri vakaparadzana neboka dielectric (zvichienderana mhando capacitors vaishandisa mhando yayo siyana), i.e. panyama dunhu iri, asi mhosva inogona vaunganidza munyika dielectric. The chikuru cho chero capacitor kukwanisa kuchengeta mutariri - capacitance uye yavose sezvavakatarirwa voltage pakati magetsi vebasa. The electrolytic capacitors vane polarities, uye vari dzinoratidzwa guru kukwanisa uye zvakasiyana-siyana voltages, bepa kutsungirira kushungurudzika zvikuru, asi duku vanokwanisa. Panewo Namano kusiyanisa vachikwanisa, asi mumwe mhando - kushandiswa kwayo.

Kazhinji hams nezvinoda dambudziko vakasarudzwa capacitors ose capacitance kana voltage. Nyanzvi kuziva: pasina kurudyi, unogona unganidza mubatanidzwa zviridzwa anoverengeka, kusanganisira bhatiri. Muna bhatiri kukabatanidzwa anobvumirwa, yakafanana uye akatevedzana chokuita kuti capacitors.

Unobva mano mu zvakafanana, zvinokwanisika kuti vabudirire kuwedzera kugona. General muna bhatiri ichi chichava akaenzana Verengai capacitances zvose (Ceq. = C1 + C2 + ...), kuti voltage norumwe ichocho chichava vakaenzana. Izvi zvinoreva kuti shoma voltage zviri capacitor, mu mukomboni iri rakaiswa, ndiye chokupedzisira chaanopa yose bhatiri.

Series kubatana kwakaita capacitors kushandiswa mhosva apo zvakakodzera kuwedzera voltage kuti anogona kukunda midziyo kana kuderedza kwairo. In musimboti ichi, zvinhu zviri zvakabatanidzwa sezvinotevera: kutanga chete mugumo mumwe, kuti ndiye "pamwe" kuti "kubvisa" mamwe. Kukwanisa noenderana capacitor muchiitiko ichi rinowanikwa neDare mutoo :. 1 / Ceq = 1 / C1 + 1 / C2 + ... Kubva neizvi, kuti capacitors maviri Ceq = C1 * C2 / (C1 + C2), uye naizvozvo, kuti bhatiri vanokwanisa achava zvishoma pane shoma vachikwanisa, kushandiswa mariri.

Capacitor kubhengi kazhinji inopa zvikabatanidzwa (zvakasiyana)
Batanidza. Kuti ngaaverenge capacitance mumwe mudziyo yakadaro umo Zvakarurama kufanana uye munhevedzano chokuita pamusoro capacitors, redunhu wakaputsika muzvikamu, ipapo successively akaverenga vanokwanisa neimwe. Nokudaro, akaverenga capacitance C12 = C1 + C2, ipapo Ceq = C12 * C3 / (C3 + C12).

Kuburikidza pakagadzwa capacitor nemabhangi vane zvakasiyana configurations uye urongwa
nokwauri, unogona kunhonga chero kukwanisa chero voltage vanofarira. Series chokuita kuti capacitors, uyewo zvabatanidzwa inoshandiswa dzakawanda akagadzirira akagadzirwa mudzidzi matunhu. Muchiitiko ichi anofanira kufunga kuti mumwe capacitor ane nomumwe parameter inokosha chaizvo - the leakage ano, anogona unbalance voltage mune yakafanana kubatana uye capacitance mu dzakatevedzana. Zvakakosha chaizvo kusarudza runodiwa shunt nemishonga.

Kana tichishanda capacitors uye zvemagetsi, usakanganwa pamusoro nemitemo Kuchengeteka uye ngozi yemagetsi kuvhunduka.
