Ndezvipi zvikamu zve inductance parameters?

1. Quality factor quality factor:

Quality factor Q chinhu chinoshandiswa kuyera hukama pakati pesimba rakachengetwa nemagetsi ekuchengetedza zvinhu (inductors kana capacitors) uye mashandisiro avo emagetsi, ayo anoratidzirwa se: Q = 2π yakanyanya kuchengetwa simba / vhiki kupera simba. Kazhinji kutaura, iyo yakakura kukosha kweQ kweiyo inductance coil, zviri nani, asi zvakakurisa zvichaita kuti kugadzikana kwedunhu rekushanda kuwedzere.

2, iyo Inductance:

Kana iyo yazvino mucoil ichichinja, iyo magineti inoyerera ichipfuura nepakati coil loop pachayo inokonzerwa neiyo yakachinja ikozvino inochinja, zvichiita kuti coil pachayo iite electromotive simba. Self-inductance coefficient ihuwandu hwemuviri hunomiririra kugona kwekuzvipinza kwekoiri. Inonziwo self-inductance kana inductance. Inoratidzwa naL. Kutora Henry (H) sechikamu, chikamu chimwe chete pazviuru zvacho chinonzi millihenh (mH), miriyoni imwe inonzi millihenh (H), uye chikamu chimwe chete pazviuru zvacho chinonzi Nahen (NH).

3. DC Resistance(DCR):

Mukuronga inductance, idiki iyo DC kuramba, zviri nani. Iyo yekuyeresa unit ndeye ohm, iyo inowanzo cherechedzwa nekukosha kwayo kukuru.

4, iyo Self-resonant frequency:

Inductor haisi chinhu chakanyanya inductive, asi zvakare ine huremu hwekugovera capacitance. Iyo resonance pane imwe frequency inokonzerwa neiyo inherent inductance uye kugovera capacitance yeinductor pachayo inonzi self-harmonic frequency, inozivikanwawo seresonance frequency. Inoratidzwa muSRF, iyo unit ndeye megahertz (MHz).

5. Impedance value:

Iyo impedance kukosha kweinductor inoreva kuwanda kwezvese zvipingamupinyi pasi pezvino (nhamba yakaoma), kusanganisira yekutaurirana uye DC zvikamu. Iyo impedance kukosha kweiyo DC chikamu ingori iyo DC kuramba kwemhepo (chaiyo chikamu), uye iyo impedance kukosha kwechikamu chekutaurirana chinosanganisira reactance (yekufungidzira chikamu) cheinductor. Mupfungwa iyi, inductor inogona zvakare kutorwa se "yekutaurirana resistor". 6. Yakatemerwa ikozvino: Iyo inopfuurira DC ikozvino intensity iyo inogona kupfuura kuburikidza ne inductor inobvumirwa. Iyo DC yazvino kusimba kwakavakirwa pahupamhi hwekushisa kusimuka kweinductor mune yakanyanya kuwedzera ambient tembiricha. Iyo yekuwedzera ikozvino ine hukama nekugona kweinductor kudzikisa kurasikirwa kwemhepo nekudzika kweDC kuramba, uye zvakare ine chekuita nekugona kweinductor kubvisa kurasikirwa kwesimba remhepo. Naizvozvo, iyo yekuwedzera ikozvino inogona kuvandudzwa nekudzikisa iyo DC kuramba kana kuwedzera inductance chiyero. Kune low-frequency current waveforms, mudzi wayo unoreva square current value
