1. Chii chinonzi inductor:
An inductor chinhu chemagetsi chinochengetedza magineti simba. Inokuvadzwa netambo imwe kana kupfuura yewaya, kazhinji iri muchimiro chekoiri. Kana ikozvino inopfuura nepainductor, inogadzira magnetic field, nokudaro kuchengetedza simba. Hunhu hukuru hweinductor ndiyo inductance yayo, inoyerwa muna Henry (H), asi mamwe mayuniti akajairika millihenry (mH) uye microhenry (μH).
2. Basic components of aninductor:
Coil:Nheyo yeinductor ironda conductive coil, kazhinji yakagadzirwa nemhangura kana aluminium waya. Nhamba yekutendeuka, dhayamita, uye kureba kwecoil inokanganisa zvakananga inductance uye maitiro ekushandisa einductor.
Magnetic musimboti:Iyo musimboti ndeye magineti zvinhu zvinoshandiswa mune inductor kuwedzera simba remagineti. Zvigadzirwa zvepakati zvakajairika zvinosanganisira ferrite, iron powder, nickel-zinc alloy, etc. Nheyo inogona kuwedzera inductance yeinductor uye kubatsira kuderedza kurasikirwa kwesimba.
Transformer Bobbin:Iyo bobbin inhengo yezvimiro inotsigira coil, kazhinji inogadzirwa nezvinhu zvisiri-magineti zvakaita sepurasitiki kana ceramic. Iyo skeleton haingo chengetedza chimiro checoil, asi inoshandawo se insulator kudzivirira mapfupi maseketi pakati pemakoiri.
Kudzivirira:Mamwe ma-inductors epamusoro-soro anogona kushandisa chivharo chekudzivirira kuderedza kukanganiswa kwekunze kwemagetsi uye kudzivirira iyo magineti inogadzirwa neiyo inductor pachayo kubva pakukanganisa nemidziyo yemagetsi yakatenderedza.
Zviteshi:Iyo terminal ndiyo interface inobatanidza inductor kudunhu. Iyo terminal inogona kunge iri muchimiro chepini, mapadhi, nezvimwe, kufambisa kuiswa kweinductor pabhodhi redunhu kana kubatana nezvimwe zvikamu.
Encapsulation:Iyo inductor inogona kuvharirwa mugomba repurasitiki kuti ipe dziviriro yemuviri, kuderedza magetsi emagetsi, uye kuwedzera simba remagetsi.
3. Mamwe akakosha maitiro emainductors:
Inductance:Chinonyanya kukosha hunhu hweinductor inductance yayo, inoratidzwa muna Henry (H), asi kazhinji mumillihenry (mH) uye microhenry (μH). Iko inductance kukosha kunoenderana neiyo geometry yecoil, nhamba yekutendeuka, iyo yakakosha zvinhu, uye kuti inovakwa sei.
DC Resistance (DCR):Iyo waya muinductor ine kumwe kupikisa, kunonzi DC kuramba. Uku kupikisa kunokonzera ikozvino kuburikidza ne inductor kuunza kupisa uye kunokanganisa kushanda kwayo.
Saturation Current:Kana ikozvino kuburikidza ne inductor inosvika kune imwe kukosha, iyo core inogona kuzara, zvichiita kuti inductance value idonhe zvakanyanya. Saturation ikozvino inoreva iyo yakanyanya DC ikozvino iyo inductor inogona kumira isati yazara.
Quality Factor (Q):Chimiro chehutano chiyero chekurasikirwa kwesimba kweinductor pane imwe nguva yakawanda. Iyo yakakwira Q kukosha inoreva kuti inductor ine yakaderera simba kurasikirwa panguva iyoyo uye kazhinji inonyanya kukosha mune yakakwirira-frequency application.
Self-Resonant Frequency (SRF):Iyo self-resonant frequency ndiyo frequency iyo inductance yeinductor inotenderera munhevedzano neyakagoverwa capacitance. Kune yakakwirira-frequency application, iyo self-resonant frequency yakakosha parameter nekuti inodzikamisa inoshanda inoshanda frequency renji yeinductor.
Yakayerwa Yazvino: Iyi ndiyo yakanyanya kukosha ikozvino iyo inductor inogona kutakura ichienderera pasina kukonzeresa kukwira kwekushisa.
Operating Temperature Range:Kushanda tembiricha yemhando yeinductor inoreva tembiricha yemhando umo iyo inductor inogona kushanda zvakajairwa. Mhando dzakasiyana dzema inductors dzinogona kuita zvakasiyana pasi pekuchinja kwekushisa.
Core Material:Iyo yakakosha zvinhu ine simba rakakura pakuita kweinductor. Zvishandiso zvakasiyana zvine magineti permeability akasiyana, kurasikirwa maitiro, uye kugadzikana kwekushisa. Zvakajairwa musimboti zvinhu zvinosanganisira ferrite, iron poda, mweya, nezvimwe.
Kurongedza:Iyo yekurongedza fomu yeinductor inokanganisa kukura kwayo kwemuviri, nzira yekuisa, uye hunhu hwekupisa kupisa. Semuyenzaniso, pamusoro-soro gomo tekinoroji (SMT) inductors akakodzera yakakwirira-density edunhu mabhodhi, nepo kuburikidza-gomba akaiswa inductors akakodzera maapplication anoda akakwira mechini simba.
Kudzivirira:Mamwe ma inductors ane dhizaini yekudzivirira kuderedza kukanganiswa kwe electromagnetic interference (EMI)
