Ihe nzacha na-agafe agafe, nke a makwaara dị ka LC filter, bụ sekit nzacha mejupụtara ngwakọta nke inductance, ike na nguzogide, nke nwere ike wepụta otu ma ọ bụ karịa harmonics.Kacha nkịtị na mfe iji passive nzacha Ọdịdị bụ jikọọ inductance na capacitance na usoro, nke nwere ike na-etolite a ala impedance uzo maka isi harmonics (3, 5 na 7);Otu nzacha a na-ege ntị, ihe nzacha elele okpukpu abụọ na nzacha ngafe dị elu bụ ihe nzacha na-agafe agafe.
Ihe nzacha na-agafe agafe bụ mmeghachi omume eriri capacitor.
Dị ka harmonic ọnọdụ nke usoro, ihe atụ, e nwere 5th harmonics, na harmonic ugboro bụ 250Hz.
N'oge a, a na-ejikọta capacitance na reactance nke nzacha na-agafe agafe, ha na-emegharị ugboro ugboro nke 250Hz.N'ihi na ngụkọta mgbochi nke abụọ resonates na usoro bụ 0, nke a na-akpọkarị obere impedance loop, n'oge a, niile 5th harmonic ga-asọba n'ime passive nzacha iji nweta nzacha mmetụta.
N'ihi usoro ihe kpatara ya, n'ikwu okwu n'ozuzu, nzacha na-agafe agafe nwere ike nweta ihe dịka 245-250Hz, yana mmetụta nzacha nwere ike iru karịa 80%.
Ọ nwere ezigbo nhọrọ ugboro ugboro na ọrụ nzacha na sekit na sistemu eletrọnịkị dị elu, ma nwee ike ịkwụsị akara na ụzụ na-abaghị uru na mpụga igwe ugboro.
