Agaghị eleghara inductance parasitic, eriri inductance, eriri igwe electromagnetic

1. A na-ewebata na inductance parasitic nke a na-apụghị ileghara anya bụ ọkara nke inductance parasitic nke kwesịrị ịtụle na PCB site na nhazi.

N'ime atụmatụ nke sekit dijitalụ dị elu, mmebi nke inductance parasitic nke vias na-ebutekarị karịa nke ike ike parasitic kpatara. Usoro inductance nke parasitic ya ga-ebelata ntinye nke capacitor ngafe na mmetụta nzacha nke sistemu ọkụ eletrik niile.

2. Anyị nwere ike iji usoro na-esonụ gbakọọ ihe dị ka parasitic inductance nke a via:

L=5.08h[Na (4h/d)+1] ebe l na-ezo aka na inductance nke via, h bụ ogologo nke via, na d bụ ​​dayameta nke etiti oghere. Enwere ike ịhụ site na usoro ahụ na dayameta nke site na oghere nwere obere mmetụta na inductance, ma ogologo nke site oghere nwere mmetụta kasịnụ na inductance. N'iji ihe atụ a dị n'elu, enwere ike ịgbakọ inductance nke oghere dị ka: l = 5.08 x 0.050 [na (4x0.050 / 0.010)+1] = 1.015 NH. Ọ bụrụ na oge ịrị elu nke mgbaàmà bụ 1nS, nkwụsị nke nhata bụ XL=TL/T10-90=3.190. Enweghị ike ileghara ụdị mgbochi a ma ọ bụrụ na enwere ugo dị elu. Ọ dị mkpa karịsịa ịmara na onye na-agafe agafe kwesịrị ịgafe site na abụọ vias mgbe ị na-ejikọta ike oyi akwa na stratum, ya mere parasitic inductance nke vias ga-abawanye nke ukwuu.

Ihe na-akpata ikpo ọkụ inductance

Ewebata ma kọwaa ihe kpatara ikpo ọkụ inductance.

1. Waya dị oke mkpa, nke ga-eme ka nguzogide nke inductor buru ibu. N'okpuru ọnọdụ na uru bara uru nke ugbu a bụ ihe doro anya, ọ bụ ihe nkịtị ka osisi ahụ na-ekpo ọkụ.

2, inductance juputara, na ụdị ahụ ọkụ a na-agbasakwa nke ukwuu.

3. Enwere nnukwu voltaji vibration na njedebe abụọ nke inductor, ya mere a na-agbanwe isi ka ọ buru ibu, nke nwere ike ibelata ọnụ ọgụgụ nke ntụgharị ma belata ogologo ahịrị. Ntugharị na-aga n'ihu, obere mgbịrịgba ugbu a, obere mfu magnetik, tumadi okpomọkụ na-eguzogide.
