Inductor yamandla e-toroidal eguquguqukayo ephezulu

Incazelo emfushane:

I-toroidal coil inductance iyisimo esihle kakhulu ku-inductance theory. Inomjikelezo kazibuthe ovaliwe kanye nezinkinga ezimbalwa ze-EMI. Isebenzisa ngokugcwele isekethe kazibuthe futhi kulula ukuyibala. It has cishe izinzuzo theory. I-toroidal coil inductance ehlanganisa konke. Nokho, kunenkinga eyodwa enkulu. , Akulula ukunwaya intambo, futhi inqubo iphathwa ngesandla.

Nakuba i-toroidal coil inductance iyisimo esihle ku-inductance, isetshenziswa kakhulu njengendlela yokucubungula isignali ngenxa yezidingo eziphezulu. Kodwa-ke, i-toroidal inductance encane isenkulu kakhulu. , Isetshenziswa kakhulu emikhiqizweni yokuxhumana ephezulu, imvamisa ephezulu.

I-toroidal coil inductor yenziwe nge-iron powder core njengento, exutshwe ne-resin, njll., ukuze igebe lomoya lisatshalaliswe ngokulinganayo ngaphakathi kwe-iron powder core. I-inductor inezinga elithile lokuzwela. Uma sibona igama elithi Air gap, siyazi ukuthi Lisetshenziswa ngamandla, ngakho-ke, i- iron powder core toroidal coil inductor iwuhlobo olusetshenziswa kakhulu lwe-inductor yamandla, kanti i-IDC ingafinyelela ngaphezu kwama-ampere angama-20.

Iyakwazi ukuphatha i-DC bias yamanje ephezulu kakhulu ene-inductance roll encane evaliwe.
Ifaneleka kakhulu Amandla aphezulu, i-AC ephezulu ne-DC Bias ku-High Switching Frequency.

Ngamanje, inductance kanye nemvamisa yokusebenza, singakunikeza imikhiqizo efanelekile kuwe.

Izinzuzo Eziyinhloko:

1. Ukuvikela okuhle kakhulu kwe-electromagnetic ngenxa yedizayini ye-toroidal

2. Amadizayini anezindleko eziphansi anemikhondo efakwe ngaphambili ye-PCB ngokufaka imbobo

3. I-iron powder cores enokulahlekelwa okuncane

4. Inkambu yokuvuza okuphansi kazibuthe

5. Izinga lokushisa lokusebenza: -25 ºC kuya +125 ºC

6. Imiklamo yangokwezifiso uma uyicela

7.Yakha ku-ROHS ethobelayo futhi uhole mahhala

1.Ikakhulu isetshenziselwa ama-voltage transformers kanye nempahla yamandla

2.Isetshenziswa kabanzi kuma-buzzers nezinhlelo ze-alamu, i-motherboard.

3.Iphelele ekuhlungeni iziphazamiso ze-symmetric
