Keeb kwm ntawmseries resonance (tseem hu ua AC tiv taus cov khoom siv ntsuas hluav taws xob)yog ib hom nrov series resonant converter nyob rau hauv lub 1960s thiab 1970s, uas muaj peev xwm ua tau zoo soft switching los ntawm tsim nyog lub sij hawm tuag. Niaj hnub nimno CNC tshuab tau ntxiv ntau qhov tseem ceeb rau qhov kev hloov pauv classic no, tsim nyog rau kev xa mus thiab kev tiv thaiv kev sim siab ntawm - muaj peev xwm, siab -voltage capacitive qauv, xws li fais fab cables, GIS keyboards, transformers, thiab lwm yam.
Hauvseries resonanceThaum muaj qhov hluav taws xob siv rau lub inductor thiab lub capacitor, vim qhov luv luv ntawm L thiab C nyob rau hauv series resonance, qhov hluav taws xob qhov hluav taws xob tsis tuaj yeem luv luv Circuit Court, yog li kev tiv thaiv yuav tsum tau nce ntxiv; Thaum tus nqi kuj tseem nyob tas mus li, txiav txim siab lub series resonant tam sim no. Nyob rau hauv cov nqe lus ntawm lub hwj chim, inductors thiab capacitors alternate kis tau tus mob yam tsis xav poob; Thaum lub capacitor tawm, nws them thaum lub inductor nqi.
Nyob rau hauv qhov tsis tu ncua voltage parallel resonant fais fab mov, lub hauv paus txhais tau tias square tam sim no ntawm inductor thiab capacitor yog tsau thiab tsuas yog nyob ntawm qhov loj ntawm inductor thiab capacitor. Tsuas yog thaum qhov chaw tam sim no nyob tas li tuaj yeem ua kom muaj zog ntxiv los hloov cov txiaj ntsig tam sim no ntawm inductor thiab capacitor. Thaum cov xwm txheej tseem tsis tau hloov pauv, lub zog kuj tseem tsis hloov pauv, zoo ib yam li series resonance.
Thaum lub cev muaj zog resonates nyob rau hauv series, vim yog qhov tsis kam ntawm lub cev muaj zog coil, qhov tam sim no ntawm lub cev muaj zog coil ntawm qhov ruaj khov voltage yog theoretically infinite. Yog li ntawd, nws tsis yog infinite, tab sis nws yuav zoo heev tshaj qhov ntsuas tam sim no. Vim yog qhov ruaj khov impedance ntawm lub cev muaj zog kauj, qhov tam sim no nce, qhov hluav taws xob ntawm ob qho kawg ntawm lub kauj nce, lub zog excitation nce, thiab lub zog nce. Txawm li cas los xij, vim muaj qhov siab tam sim no, lub cev muaj zog coil yog nquag hlawv tawm.
Nyob rau hauv parallel resonance ntawm parallel capacitor, vim muaj qhov muaj qhov hluav taws xob thiab qhov hluav taws xob hla lub inductor thiab capacitor, tam sim no ntawm ob qho kawg ntawm inductor yog tas li. Txawm li cas los xij, vim qhov nyiaj them ntawm lub capacitor, theem ntawm qhov hluav taws xob thiab tam sim no yog tib yam, yog li ua kom lub zog, uas yog, theem kaum ntawm p=u * i * cos. Lub hauv paus ntsiab lus ntawm parallel resonance yog qhov tam sim no, uas txawv me ntsis ntawm qhov no. Vim yog qhov tsis tu ncua ntawm qhov tam sim no, thaum qhov tam sim no resonates nyob rau hauv parallel, ob qhov kawg ntawm L thiab C yog qhib heev, thiab qhov kev tiv thaiv ncaj qha dhau los ntawm qhov tam sim no, uas yog, tam sim no ntws los ntawm qhov tam sim no, uas ua rau kom qhov voltage ntawm ob qho tag nrho, nce voltage ntawm ob kawg ntawm L thiab C, thiab thaum kawg ua rau muaj kev nce rau tam sim no.
Cov xwm txheej yooj yim rau series resonance yog:
1. Kev txhais ntawm series resonance: Nyob rau hauv RLC series Circuit Court, thaum lub davhlau ya nyob twg voltage thiab tam sim no ntawm lub Circuit Court nyob rau hauv tib theem, lub Circuit Court yog resistive, thiab lub xeev ntawm lub Circuit Court hu ua series resonance.
2. Cov xwm txheej rau series resonance.
3. Cov txheej txheem rau kev txheeb xyuas circuits kom ua tiav resonance:
(1) Thaum lub zog zaus tsis tu ncua, qhov loj ntawm L lossis C tuaj yeem hloov kho kom ua tiav resonance. (2) Thaum qhov ntsuas tsis tu ncua L thiab C tsis tu ncua, resonance tuaj yeem ua tiav los ntawm kev hloov qhov zaus ntawm cov khoom siv hluav taws xob.
