High voltage ceramic capacitors inogonawo kushandiswa se decoupling capacitors. Aya ma capacitors akagadzirirwa kushanda pamagetsi epamusoro uye anogona kushandiswa kugadzirisa shanduko yemagetsi ikozvino mudhiraivha yekufambisa kudzivirira kupindirana uye kuderedza kupindira kwepamusoro-frequency kupindira. Nekudaro, mhando dzakasiyana uye mhando dzeyakakwira voltage ceramic capacitors dzinofanirwa kusarudzwa zvichienderana nezvinodiwa zvedunhu uye voltage / ikozvino zviyero zvezvikamu zvinoshandiswa mudunhu. Zvinokurudzirwa kubvunza mugadziri www.hv-caps.com kana mugovera kuona kuti yakasarudzwa yakakwirira voltage ceramic capacitor yakakodzera kushandiswa se decoupling capacitor mune chaiyo application.
heino mimwe mienzaniso yedhiyagiramu yedunhu inoratidza kushandiswa kwe decoupling capacitors:
Mumufananidzo uyu wedunhu, iyo capacitor (C) ndiyo decoupling capacitor yakabatana pakati pesimba rekupa uye pasi. Inobatsira kubvisa iyo yakakwirira-frequency ruzha kubva kune yekuisa chiratidzo inogadzirwa nekuda kwekuchinja uye zvimwe zvinhu.
2. Digital circuit inoshandisa decoupling capacitors
Mumufananidzo uyu wedunhu, maviri decoupling capacitors (C1 neC2) anoshandiswa, imwe pamhiri pemutyairi uye imwe pamutoro. Iwo capacitors anobatsira kubvisa ruzha rwakagadzirwa nekuda kwekuchinja, kuderedza kubatanidza uye kupindira pakati pemutyairi nemutoro.
3. Simba rekushandisa redunhu uchishandisa
Mumufananidzo uyu wedunhu, decoupling capacitor (C2) inoshandiswa kugadzirisa kubuda kwemagetsi emagetsi. Inobatsira kusefa ruzha runogadzirwa mumagetsi emagetsi uye kuderedza kubatanidza uye kukanganisa pakati pedunhu nemidziyo inoshandisa magetsi.
Kutevera ndiko Kunowanzo bvunza mubvunzo nezve "decoupling capacitors"
1) Chii chinonzi decoupling capacitors?
Decoupling capacitors zvinhu zvemagetsi zvinobatsira kusefa kunze kwepamusoro-frequency ruzha uye kushanduka kwemagetsi. Yakabatanidzwa pakati pesimba rekupa njanji uye pasi, ivo vanoita senge yakaderera-impedance nzira kune yakakwira mafrequency kusvika pasi, iyo inoderedza huwandu hweruzha runopinda mudunhu.
2) Ko decoupling capacitors inoshanda sei?
Decoupling capacitors inogadzira simba renguva pfupi rekupa masaini epamusoro-frequency kushandura pakati pesimba uye pasi njanji. Nekuvharira yakakwira-frequency simba pasi, vanogona kuderedza magetsi ekupa ruzha uye kudzikamisa kubatana kwemasaini akasiyana.
3) Ndekupi kunoshandiswa decoupling capacitors?
Decoupling capacitors inowanzoshandiswa mumidziyo yemagetsi senge microprocessors, integrated circuits, amplifiers, uye magetsi emagetsi. Izvo zvinoshandiswawo mu-high-frequency applications uye uko yakaderera chiratidzo-kune-ruzha-ratio yakakosha.
4) Chii chinonzi capacitor shunting?
Capacitor shunting chiitiko chekubatanidza capacitor pakati penodhi mbiri mune yemagetsi dunhu kuderedza ruzha kana chiratidzo chekubatanidza pakati pavo. Inowanzo shandiswa kune decoupling capacitors senzira yekuvandudza simba rekupa simba uye kudzvinyirira EMI.
5) Ko decoupling capacitors inoderedza sei ruzha rwepasi?
Decoupling capacitors inoderedza ruzha rwepasi nekupa yakaderera-impedance nzira yeakakwira-frequency masaini kusvika pasi. Iyo capacitor inoshanda senguva pfupi-simba sosi uye inobatsira kudzikamisa huwandu hwesimba hunogona kufamba nendege yepasi.
Ehe, decoupling capacitors inogona kudzvanya EMI nekudzikisa huwandu hwepamusoro-frequency ruzha runopinda mudunhu. Ivo vanopa yakaderera-impedance nzira yeakakwira-frequency masaini kusvika pasi, achidzikamisa huwandu hweruzha rwakarasika runogona kubatana pane mamwe masaini.
7) Nei decoupling capacitors yakakosha mumaseketi emagetsi?
Decoupling capacitors inoita basa rakakosha mumagetsi edunhu dhizaini nekudzikisa ruzha uye kushanduka kwemagetsi kunogona kukanganisa mashandiro ehurongwa. Ivo vanobatsira kuchengetedza kutendeseka kwechiratidzo, kudzikamisa EMI uye ruzha rwepasi, kudzivirira kubva pakushatisa kwemagetsi emagetsi, uye kunatsiridza kuita kwese dunhu.
8) Ko ruzha rwepamusoro-ruzha uye kubatanidza kwemasaini zvinokanganisa sei maseketi emagetsi?
High-frequency ruzha uye chiratidzo chekubatanidza zvinogona kutungamirira mukuderedza kushanda uye kuvimbika mumasekete emagetsi. Vanogona kukonzera kukanganiswa kwechiratidzo kusingadiwe, kuderedza ruzha, uye kuwedzera njodzi yekutadza kwehurongwa.
9）Unosarudza sei iwo akakodzera decoupling capacitors yechishandiso chako?
Kusarudzwa kwe decoupling capacitors kunoenderana nezvinodiwa zvekushandisa senge frequency renji, voltage rating, uye capacitance kukosha. Izvo zvinoenderanawo nehuwandu hwehuzha huripo muhurongwa uye zvipingamupinyi zvebhajeti.
10）Ndeapi mabhenefiti ekushandisa decoupling capacitors mumudziyo wemagetsi?
Zvakanakira kushandisa decoupling capacitors mumidziyo yemagetsi zvinosanganisira zvirinani chiratidzo chemhando, yakagadziridzwa kugadzikana kwedunhu, kuderedzwa kwemagetsi ekupa ruzha, uye dziviriro kubva kuEMI. Vanogonawo kubatsira kuderedza ruzha rwepasi uye kugadzirisa kuvimbika kwese kwehurongwa.
Iyi ingori mienzaniso mishoma yemadhiyamu edunhu anoshandisa decoupling capacitors. Iyo chaiyo yedunhu uye decoupling capacitor kukosha inoshandiswa ichasiyana zvichienderana nekushandiswa uye zvinodiwa zvedunhu.
